What is CCD rearview car camera system

What is CCD rearview car camera system?

Firstly, I think if you want to know about the CCD rearview car camera system, you should understand what CCD is and what CCD rearview car camera is, then you will realize more about CCD rearview car camera system.

What is the CCD?  CCD ( Charge-coupled Device) is a semiconductor device, which can convert optical image into digital signals. The tiny photosensitive material on the CCD is called pixel, and more pixels on the CCD means higher resolution of picture. There are many arranged photodiode on the CCD, which can sense light and transform light signals into the electric signals, then CCD convert electric signals into digital picture signals though enlarging the external sample and analog data.

What is the CCD camera?  The CCD camera focuses the image of the object on the CCD chip through the lens, then CCD accumulates corresponding proportion of charges according to light intensity, these charges will covert into video signal under the control of video sequence, thus you can watch the video when the video signal is connected with monitor or TV.

The principle and composition of CCD rearview car camera system

The principle of CCD rearview car camera system : CCD rearview car camera system is an improvement from original reversing radar. The car camera mounted on the rear end of the car,  take the picture and send the video signal into car display near the driver’s position though transmission line, which can make the driver see the environmental obstacle on time around the rear end of the car and expanding the view of driver, also increase the safety efficiency and make sure driver have a safe reversing action.

The composition of CCD rearview car camera system: car display, reversing camera and transmission line.

Generally speaking, the CCD rearview car camera exist for drivers could having a good view behind of the car so that they can have a safe reversing and avoid to injury passerby .

What is AHD camera and its advantages

What is AHD camera and its advantages ?

AHD is short for Analog High Definition, so AHD camera is analog high-definition camera, transmission signal is the high-definition analog signal. Talking about high definition, in short, we usually call the video high definition with the physical resolution more than 720p, referred to as HD.

AHD technology can achieve the reliable transmission of ultra long distance (500 meters) high-definition video signal on the existing analog transmission line. It adopts advanced Y/C signal separation and simulation filtering technology, which can effectively reduce the color noise in high frequency area, image reducibility is better. Compared with the traditional high definition products, AHD camera image quality has a qualitative leap and upgrade, the highest clarity can be equivalent to the full network HD 1080 level.

AHD camera features and advantages:

  • more clear: advanced bright color separation, signal filtering, 3D noise reduction technology, image clarity higher, better image reducibility ;
  • transmission distance: use coaxial transmission, ordinary 75-5 line can transit up to 500 meters;
  • zero delay: captured data transmitted to the monitor without encoded, real-time and high fidelity;
  • compatible: compatible with ordinary D1/960H, compatible with analog peripherals (including the distributor, matrix, etc.);
  • easy to operate: support OSD menu design, set as you like;
  • inexpensive: ordinary simulation price for high definition quality product;
  • high integration: AHD front-end chip price for high-definition quality products;
  • open standards: open standards to third party, compatible with other manufacturers’ AHD products, accelerate the market development.

AHD camera follows the method of simulating standard definition transmission, which can reduce the complexity of construction and deployment, reduce the cost of auxiliary materials and maintain complexity as well as technical requirements of construction personnel. It is extremely suitable for upgrading the old system, you can easily upgrade from standard definition to high definition without change the original system . In addition, high definition quality with standard defintion price, make the AHD camera has a very large development space both in the civilian and industrial market ( such as AHD car camera ).

How to choose suitable car reverse camera

How to choose suitable car reverse camera ?

There are two types of reverse car camera: wired reverse camera and wireless reverse camera, wired reverse camera is simple and reliable, but need wiring inside the car or other vehicle; wireless  reverse camera does not need wiring along the interior of car or vehicle,  so it is easy to install, but you need additional wireless receiver . However, current wireless receiver receiving effect is still not very ideal, so most reversing cameras in the market are still wired reverse camera. You can choose wired reverse camera from the following aspects :

Camera Chip

Camera chip is the most important part in reversing camera , they can be divided into CCD and CMOS two kinds. CMOS is mainly used in low image quality products,  its advantages are manufacturing costs and power consumption is lower than the CCD, the disadvantage is the CMOS camera has high requirements for the light source;  CCD chip is mainly used in photography, camera , some high-end technical components also comes with a video capture card.  CCD and CMOS in the technical and performance gap is large, in general, CCD effect is better, but the price is more expensive.

Resolution

Resolution is one of the important indicators when choosing reverse cameras. In general, high-definition reverse camera, its image quality will be better, reverse camera resolution above 420 line has become a mainstream in reversing camera products,  380 lines reverse camera, if debugging properly, can still be a good choice. However, according to different camera chip level, different components, including different technicians’ debugging level , the same chip or the same level reverse camera product output quality may be different; on the contrary, high-definition reverse camera products night vision effect will be reduced.

Night vision

Night vision effect related with reverse camera resolution, higher resolution car reversing camera night vision effect will not be very good, this is because the chip itself, but good quality reverse cameras should have night vision function, and will not affect the image output effect; although the color may be worse, but clearly should not a problem. Car reverse camera with built in infrared light night vision effect will be more clearly visible.

Waterproof

Reversing camera products are basically equipped with waterproof function.
Summary: choose the right reverse camera from the camera aspects per your requirements, the most important thing is to check and  compare the actual image affect.

Is buying and using dashboard camera legal in Germany

Is buying and using dashboard camera legal in Germany ?

We may have heard of a story before: a driver was taken to court for using a dashcam – Basically, he’d been driving around with his dashcam switched on, and anytime he saw anybody breaking the law, he would report them to the police. The authorities wanted him to stop, why? Because the court felt that it basically amounted to vigilantism , Also, there was an issue of privacy: German privacy laws mean that normally, you can’t just film people without their knowledge.

So many people feel that buying and using dashboard camera is illegal in Germany , actually it is not. Germany government never ban the dashboard camera at all, however , dashboard camera is regarded as surveillance camera, you should use it without against privacy law, which means:

You have to unmask / blur a person if he asks you for it and the person is not a public person ( like popular star, big CEO etc ) .

You can take pictures of public events and publish them, but if you focus on a person you have to ask for permission to publish the picture. They just can protest and you just have to react, but that not illegal.

You can using dashboard camera to protect your own safety, properties when pedestrians, cyclists and other drivers do stupid things.

So actually in current years, every car owner should install a dashboard camera in his own vehicle, we hope these captured video won’t have to submitted to court for responsibility identification. But once needed, they can protect us.

Is it legal to use car dashboard camera in United States

Is it legal to use car dashboard camera in United States ?

It is 100% legal to install a dashboard camera for your car, truck and other kind of vehicles, and legal to capture videos around the vehicles.

But sharing those captured videos (which have human faces, other people’s car license plates etc ) to friend or social network such as Youtube, facebook still haven’t got a confident answer on the legality, since these videos may violate other people’s privacy. So we strongly recommend to use the dashboard camera as a backup usage,  so it can be helpful for Police and Insurance company to identify responsibilities in a traffic accident. And if you want to share the beauty captured during your trip with your friends, better add some mask on the human faces and others’ car license plate.

How to hide the dash camera wires inside the car or other vehicles

How to hide the dash camera wires inside the car or other vehicles ?

Today, we are glad to writing a post on how to hide the dash camera wires into the nooks and crannies around the perimeter of the vehicle inner space, now there’s a lot of spots that you can hide a wire in, and we’re going to jump into some of them to organize your wires easily ,ideally you will have to use some wire clips, usually they’re included in your dash camera kits, the wire clip has an adhesive on one side and on the back there is a hook, you can actually buy these wire clips online, they’re pretty cheap as well, otherwise you can also use some tapes. I am going to use wire clips in the visible areas but underneath the dashboard, i will use the tapes instead.

dashboard camera wiring diagram

Take your cord up into the headliner and start tucking away until you reach the side, now run your wire until you’re under the dash, go towards the center dashboard and stash away your excess cables on the side, then plug in, any extra slack wires should be neatly tucked away beside your console, you can easily run the wire upwards into the headliner on the new vehicles, however you have to check if there’s a cover you can hide the cable behind on older vehicles, you can tape your wiring to the mirrors, check if it’s closed otherwise keep it straight, there’s no need to attach it to the window, the headliner can be gently pulled down and the wire pushed in to start stuffing, I recommend going towards the passenger side, as a fallen cable won’t interfere driving, but it’s really up to you, once you reach the end, i found running the cabling inside the weather sealing or side trim is easier and hides more of the cabling, start by examining your door frame for areas where the cable is securely held and won’t share the cable when the door is closed, the alternative is to run it alongside the windshield, you might have to use tape or a wire guide as the trim can be difficult to press int.

Once you reach the end, you will have to bring it back out and drop it alongside your board, again look for any areas you can place your cabling, if nothing exists make sure the cable stays straight either from pulling it underneath your dashboard or by using a wire guide, this ensures it won’t be caught inside your door, whatever method you choose the goal is to reach underneath your dashboard, once you look for any sort of hooks or areas you can wedge your cable into, you can go nuts with cable ties or tape here as it won’t be seen, if you’re lazy you can place your floor mat over the cable, making sure any passengers won’t get caught up on the wiring. I’ve used this method before a couple months with no damage and no problems, once the cable is beside your dashboard, shove all the loose wiring beside your seat and plug the end in, so now you’re done, congratulations.

Tutorial on how to DIY installation of rearview car camera and lcd monitor

Tutorial on how to DIY installation of rearview car camera and lcd monitor

I was always considering to write a tutorial on how to install the rearview backup camera and lcd display together to user’s own car, as i have seen many consumers prefer to buy rear view backup camera and lcd monitor themselves directly from manufacturer instead of buy from a reseller or an agent,  and then DIY installation themselves, as this will ensure them adopting the best quality cameras and monitors with the lowest budget, at the same time, the satisfaction is a ultimate proud.  However, when i sourcing resources on the internet, i found a DIY video published by Dr. Fuss really perfect, so i decide to share this video to Luview rearview car camera and lcd monitor users ;I have also reorganize the words, so it is more readable for those who have limited access to Youtube. Below is the video and articles, i hope it could helps our user or buyer.

It is dr. fuss here and in this video,I will be replacing the rear view camera which I installed about maybe six seven years ago it’s a wireless one and it really didn’t work that well, a lot of interference, so I’m going to be removing this old one here and replacing it with a wired one so I went on eBay and picked up this 4.3 inch LCD display here and also this rear view camera, let me show you what’s inside, so anyways this is the 4.3 inch LCD with a cabling inside, also here is the serial camera comes with a long wire so you can run it from the back to the front of the car power cable, this is the camera itself very small very compact, so before I installed this new camera in the LCD screen I ran a quick test, basically a wired both the camera and LCD to my 12 volt power supply here and the quick test powers up LCD screen looks good, camera looks good too.

so who’s on this side you don’t have to remove the whole thing, using the association good access to the wire then for the rubber seal basically just pull on the rubber seal, I remove this go around painting all the remove the whole thing the side you need to work, pull the rest here, now over here you got these plastic strap hooks here carefully, yeah you don’t know loosen that right off and uh there’s another one down below here over here with this bottom piece.

Basically there are Clips behind it and Clips underneath here so pull it up this way first on the side panel, basically just pull it back release the clips, you also need to follow this tooth, here is rubber – and then you put access feetthe wire from the back hatch into the car, so the first thing I’m going to do is take the long RCA cable and feed it through this rubber tube here and into the back pouch here, now I do have the old wiring here so I might use that to help me guide that through, but if not basically use a screwdriver or coat hanger and feed it through, I mean the length of this not very long so it’s not that difficult, so we’re going up this end, we want to next is basically put the camera where you want it then once it’s lined up, mark the hole and then we’ll go ahead and mount camera, but the two screws up came the account so that’s what the camera looks like, is it mounted now, we’re going to pass this RCA into the car, so there’s really no easy way about it on this vehicle, some other vehicles you might be able to find a bigger hole but I’m going to have to use a step up, you need it and put a hole right in the middle here, and then feet this wire through, I’m gonna slip a piece of tape in here just to give it a little bit of smoother edge, so when a wire there’s not gonna keep rubbing on it, the close up that hole I got some ducting aluminum tape, and get these at all home people, I cut a piece off and I’m gonna cover the hole with this too, now one thing I just realizes this cable I brought from the inside of the car to the hatch here is is an RCA cable, I have this cable which inside has two conductors, one is going to be for your reverse 12-volt and the other ones in background, and we run this in parallel with this cable here, now that you have the water spread and go ahead and close something from it that goes to the proper holes here, then we’ll carefully feed the wire so go ahead and route the wires along here and use some tie wraps to talk to the existing wires.

Now I want to point out the 20-foot RCA cable also has this red lead now on both sides, there is this red wire and you can use it to carry your reverse 12’o, and that’s why i’m going to use it for, but I’m going to bring in my home power which I ran the wire for the video and then also ran a power cable, so this power cables that go back into the car and connect to the reverse 12-volt, so what I’m going to do is that this wire that goes back into the car and connect to that reverse 12-volt it’s going to power, I’m going to connect to the red here except power the camera and also I’m not tap this wire from the RCA cable onto the 12-volt, also here and this wire that run all the way to the front of the car is going to get the reverse 12-volt to the LCD screen, so that’s how I’m gonna power everything using the reverse light here.

Okay now that everything is connected, go ahead and select the power to the power connector on the camera and using Tyra secure the wire here, so at this point the camera installation is done, we just gotta put the cover back on now, also the hatches put back together, go ahead route the wires along the side here into the car.

Okay let me talk about what am i do here now, because I had a previous reverse camera, I already tapped the reverse light on the back of this car and that’s what this blue wire is, and all I did last time was to basically pull this light out, you have the wiring harness and you’ll need a voltmeter, okay you’re going to need a voltmeter, and probe the wire that goes to the reverse light, you need to basically probe it, so one is going to be on the wire and one is going to be on ground, and that’s that’s how you read the 12-volt, have someone help you put the car in reverse and then once it’s in reverse then you’ll see that there is 12 volt on the wire, so I brought this far in and it goes straight to that wire on the reverse, okay now what I’ll do here is at the ground I’m going to basically tap a ring terminal like you see here and then screw it on to the side of the car, that will give me the ground and again the red wire is going to be the reverse 12v, oh that connects to the backup reverse lights and wiring, okay so here you see the part where the ground is tapped into the chassis of the car, and I tapped a reverse cameras power 12 volt into the reverse wire a dipole, so the next thing you need to do is the other end of the RCA cable is to run this cable, along the inside of the car and all the way to the front of the vehicle.

Now to get the wire from here all the way over behind the third row, you can use like a co hanger like I’m doing here, and this just put the coat hanger all the way down to the bottom here, and pull it through and that’s what I’ve done here, so here’s the RCA, at this point you can go ahead and close everything up at the back now, here I’m at the side door and with most cars these sidesteps you basically pull up, they’re clips on it, I can just remove it.

Now when you get the wire to the b-pillar, that’s a pillow right behind the driver’s seat, this panel typically is quite difficult to take out, because the seatbelts also anchor to here, so what I typically do is tuck it underneath, stick your finger underneath and tuck the wire underneath, so that’s out of the way just run this all the way to the front door and then put the panel back on, when you’re done just feed the wire follow the bundle of wire that is already there now on the a-pillar, basically what you want to do is pull on the weather stripping here all the way up and then over here again there’ll be clips, just want to give a hand in there and put to release the clips as you can see with its RCA cable is too short, I’m sure if it was installed in a sedan then this cable is probably long enough but I have to bring this all the way up on the a-pillar, all the way up here and the LCD wire is not very long so so what I have here is an extension cable basically is one RCA cable with an adapter in the middle, which will allow me to connect this end to that end and extend this video output cable all the way up to the LCD monitor, the other thing I’ll need to extend is going to be the reverse 12-volt red wire that was hooked up at the back and I’m going to extend that up to the a pillar also underneath it – I’m going to find a ground, usually we’ll find a bolt of some sort or you can tap your own ground underneath the dash, and that’ll be my ground so that will complete the connection. I have the video which is the yellow RCA, the red cable is my reverse 12-volt and on my ground, that’s all that’s needed to complete the wiring so I ran the water up through this groove make sure tuck it in, so it doesn’t get pinched all the way up here and I also ran the extension power cable, I have the ground and the reverse 12-volt up here is the extension for the video RCA, so I’ve decided to mount the LCD display above the rear view mirror, so the back here on the base there is a double sided tape, just peel the backing off and stick it on so right now I’m just tucking all the wires up top on the headliner and then close this off and that’s it.

So let me test it out, it’s pretty late outside, so it’s dark outside and this test will give you an idea how well the camera works, so I’ll put it in reverse and illuminates probably good, 15 feet there, and the camera came on pretty quickly, put in the park turns off and we put it back in reverse again, so it comes down pretty quickly, now let me give you another look of the camera at the back, very low profile it looked like it’s a factory camera, and one thing I didn’t mention earlier is about the camera and the LCD that I bought is from eBay, but different sellers, I bought it like that because I wanted to get the lowest price, the camera I paid about twelve dollars, and the LCD display I paid twenty dollars, if you buy as a kit, usually it will be a little more expensive, so just be aware of that and if you have any questions, then leave me us a comment.

Why CMOS sensor rearview car camera

Why CMOS sensor rearview car camera ?

Since the rearview car camera is became more and more important in modern life,espeically for the new driver, and do you know its technology and craftwork requirements? For automotive applications, car camera and mobile phone camera use the same camera sensor, CMOS instead of CCD sensor, the main three reasons as below:

First of all, the sensor used in rearview car camera should have the primary feature is: fast. Especially at high speed driving occasion, the rear view car camera must be able to record critical driving conditions.In fact, CMOS is a faster image acquisition technology – the unit in the MCOS sensor is usually controlled and read out by three transistors, which significantly accelerates the image acquisition process. At present, CMOS based high performance cameras can achieve a level of about 5,000 frames per second.

Secondly, CMOS sensors also have the advantage of digital image processing. CCD sensors typically provide analog TSC / PAL signals, which may have to be converted using an additional AD converter, or the CCD sensor should work with a progressive scan method display for digital image output. In either case, using CCD cameras to provide digital video signals significantly increase the complexity of the system; and CMOS sensor can provide LVDS or digital output signal, lcd display can be directly, without delay to deal with these signals.

Thirdly, CMOS sensor cost is bit lower than ccd sensor . And, when there is a strong light into the CMOS sensor, CMOS sensor will not produce Smear noise as CCD sensor. This will reduce the adjustment time due to operational errors.

Can the car rearview mirror be replaced with cameras

Can the car rearview mirror be replaced with cameras ?

Of course, and this is the future trend.

Nissan in 2010 at the Geneva Motor Show released its intelligent rearview mirror. This intelligent rearview mirror was built in the LCD monitor board, when necessary, the rear 1.3 million pixel camera can send the rear images to the rearview mirror display panel, showing details behind the car on the screen.

On 2014 Hannover International Commercial Vehicle Show, Mercedes-Benz use a rearview camera instead of the rearview mirror in its concept truck.

Tesla Model X, also canceled the rearview mirror in the first appearance, use micro-camera instead (but this has violate the relevant US regulations, they had to back to the traditional rearview mirror on the final version).

With the development of camera technology and manufacturing costs have been reduced, I believe that more and more car manufacturer will try this technology. So what is the advantage of using cameras instead of rearview mirrors ?

1. Give the driver a wider view. Using four to five wide angle cameras arranged on the front, side, back of the vehicle, providing 360 degree aerial view of the vehicle without dead points. Curved mirror due to the optical observation of the angle and the impact of optical distortion, imaging range and quality are subject to certain restrictions. In addition, through the visual
sensor, you can achieve automatic headlamp control, when the vehicle close to the oncoming car or overtaking, automatically detecting the lights and self-regulating the far and near light, to ensure that the driver has a good vision. Furthermore, use low-sensitivity sensors and anti-glare design, can ensure the driver full of vision space for safe driving and better protection.

2. Reduce the drag coefficient and reduce fuel consumption. Researchers through two car model: one with outer mirrors and door handles, the other without a rearview mirror and door handle; and then through the CFD simulation software to analyze the drag coefficient, and finally get the following results:
If cancel the rearview mirror and door handle,vehicle upwind area reduced by 2.56%, the car driving wind resistance decreased by 12.56%. From the above results we can seen the effect is more significant if remove the rearview mirrors.

3. More possibilities for styling. We all know that the earliest car is without rearview mirror, driver need to look back when reversing, the emergence of rearview mirror is a great leap for the safety of the car, but the car’s shape is also limited, because it is regulatory requirements. Cancel the rearview mirror, it is certainly helpful for the designers. I believe that with the leap in electronic technology, the camera can be smaller and smaller, until we can arrange it in a very small space.

However, traditional rearview mirror has not really been replaced. First because of regulatory factors, but the cameras still have a lot of key technology is not completely resolved. Such as high reliability, after all, electronic components, relative to a glass, the reliability is lower, once broken, driver really had go back to the old car years.

These technical problems, cost problem, will be resolved one by one with the technology development, twenty years ago, many cars did not have reverse carmeras, reversing sensor, now you can see these things are standard equipment for cars.So let’s wait and see the years of car rearview mirror totally replaced by car cameras.

What is the difference between home cameras and car cameras

What is the difference between home cameras and car cameras ?

In daily life, we have been used a lot of mobile phone camera and computer camera , can these cameras be used as car cameras ? What is the difference ? Shenzhen Luview Co., Ltd will tell you how to distinguish between car cameras and home cameras:

Car camera has certain requirements for installation , it requires a small and light installation size so that the passenger’s driving environment won’t be affected and the cameras needed to be fixed firmly to avoid affect monitoring effect, there is a certain degree for anti shock performance, the most important is that the car camera need to have a built in infrared light, so it can easy easy to monitor surroundings even when the lightness is not good, such as in the dark night.

Home camera is mostly used in interior design, unlike the car reversing camera mainly for outdoor usage, the production process, waterproof level, anti aging performance, anti shock performance etc are not in the same industrial technology level, which is why the market price of the car camera usually several times more expensive than home or computer cameras.

In addition, the car camera has been improved in night vision effect, high definition and wide view angle,the car camera use the industrial level camera chip.

Again, the car camera pixels usually much lower than the mobile phone camera pixels, the newly released iPhone 8 mobile phone camera pixels have reached 20 million pixels, while the high-end car rearview camera pixels is only 100 million, and general car camera pixels only about 300,000.
