Since the traffic fraud is more common now, dash cam ( also being called dashboard camera, dashcam, dash camera,dashboard cam;they are actually the same thing ) has become a must buy equipment for car. In addition to retaining evidence and protect drivers themselves, dash cam can also record the funny moments and along landscape during car running.

But there are so many dash cam on the market, the price ranging from a few bucks to several hundreds, and the high price dash cam usually come with many functions, but after use you may found these functions not so useful as the purchasing guide said.How can we avoid buying traps, not waste money? let’s take a look at below.

Trap one: camera lens pixels the higher the better

Some purchasing guide will recommend relatively high pixel dash cam, current dash cam pixels in the market ranging from several millions to 10 million pixels, naturally, the higher pixels the more expensive. But in general, 2 million pixels 1080P dash cam is powerful enough to capture clear driving videos. Higher pixel sensors will not only reduce the recording time, but also greatly increase the number of memory card rewrite times,which will lead to shorter memory card life.

Trap two: the more function the better

Some purchasing guide will recommend consumer to purchase a all-in-one dash cam, with additional electronic dog, reversing camera, GPS navigation function or something besides the basic driving video recording function, and the price will naturally rising. In fact, because multiple functions share the same CPU, all-in-one dash cam performance will be significantly reduced,and the effect can’t up to the effect as it said,besides,the service life will be shorter than the single function dash cam too.

Trap three: dash cam performance with Ambarella chip will be better

Most salesman will tell you that his dash cam is adopt the Ambarella A7 chip, but they just will not tell you the exact A7 chip number.The A7 series Ambarella chip is divided into high,middle,low three different classes, respectively is LA70, LA50 / LA55, LA30, low grade chip A7 chip performance naturally not as good as high end Ambarella A7 chip.

Trap four: view angle the wider the better

Some purchasing guide will recommend super wide angle dash cam, with wide view angle its blind area will be less. In fact,although wide angle can reduce the blind area, but it will distort the screen too, the wider view angle the more serious distortion, video effects will be affected too. In general, 120-150 degrees view angle dash cam can meet most driver’s requirements. Before you buy a 170 degrees or even 200 degrees view angle dash cam,consider it carefully .

Trap five: dash cam can be 24 hour monitoring while parking

Some high end car owners will think about a 24 hour parking monitoring dash cam, because their exposed car used to be damaged while parking.However, on the one hand the cam built-in battery and memory card can only support video of 8-16 hours, it is difficult to achieve 24-hour monitoring; on the other hand the dash cam monitoring angle is limited, certainly can’t achieve all-round monitoring. So you want to have a 24 hours monitoring dash cam for your car is not realistic, if the purchasing guide recommend this feature to you, then he must be lying .

Although is it a bit complex to choose a dash cam driving recorder,as long as you avoid these traps, being cheat choice may greatly reduced.

Most driver driving a car in less than 90 minutes per day, while the 32 G SD card can record 320 minutes full 1080p HD video, recorded video can be saved for more than three days, for most people,it is enough.If you want to record video around your car the whole day, you must adopt a 64 G sd card.So we recommend 32 G SD card for Luview dashboard car camera user.

Besides,SD card reliability and service life is very important,at least class 10 is required, otherwise it can not keep up with high definition video read and write speed. We recommend Sandisk high durable series 32 GB SD card,it can record more than 5000 hours under temperature of -25ºC to 85ºC,which means it can work almost in all areas and conditions.Although it is a bit more expensive than those bad quality ones,but it is more reliable.

Currently there are a lot of dashboard car camera brand and models on the market with different technical specifications.For common consumer,we may focus more on the camera pixels.Currently 1080p or 1296p dashboard camera is very common on the market,1440p dashboard camera is still not very common as they are mainly used on high end car.Is it the truth that 1296p dashboard camera is better than 1080p dashboard camera ? This should be discussed.

For anti road fraud purpose dashboard camera, 1080p definition is clear enough, too high definition will greatly reduce the sd card life as well as reducing the recording time. In addition, due to each pixel lighting lux reduced for 1296p dashboard camera,the night vision effect can be worse, it is not worth to do that.

We may experience this: when we watch 720p video or film on the computer from internet, ,720p video has been very clear, even up to 1080p source, definition is not obvious improved,but your surfing speed will be affected a lot. That is because of 1080p video size is two times compared with 720p video, and 1296p video size is around 1.4 times of 1080p video.That is,for a same SD card,storage the 1290p video not only the video recording time reduced by 30%, but also greatly increase repeated reading and writing times,which would definitely reduce the SD card life span.

Similarly, 24 fps of the video has been very clear and smooth,increasing 30 fps to 60 fps , will also cause reducing of video record time, and shorter SD card life span.

Consumers should focus on practicability and durability of dashboard camera, not the higher technical parameters the better.
