If you have selected a reliable brand to buy a registratore di guida, you need to focus on analyzing some product parameter before you purchasing a driving recorder, it seems like shooting angle, resolution of picture, compressed format, caching, and we also need to know whether the video can be closed manually; whether it can record a video normally at emergent situation; whether no jamming to other electric products and whether purchasing with card etc.

Shooting angle

The shooting angle is 100 degree for ordinary driving recorder, which is basically  enough to make sure shooting the two lane side of vehicle. Of course, bigger angle is better, and the expense is more too.

Resolution of picture

Generally video resolution  is 1280 * 720, which can promise take a clear picture for license plate in ahead, and license plate of side lane will be a little vague in the driving recorder. In addition, the photosensitive ability of SMOS chip in driving recorder and the quality of lens’ glass is connected with the shooting effect at night.

Compressed format

Most of driving recorder use compressed format H.264 .  Without a good compressed format but not losing frame, which require bigger storage capacity and higher reading speed of memory card. The size of 1 minute fragment of 720p resolution H.264 compression is about 60MB. In terms of drivers, it is helpful to choose a reasonable recording interval and volume for providing accident evidence in time, and 1 minutes as a interval time is appropriate.

Cache

A bigger volume of cache can bring smoother video and better memory card compatibility.

Emergency video

If there is a important video you want to leave, and the driving recorder also need to shoot video next,  which cause the important video will be deleted at the next time, for solving this situation, it occurs a emergency video design for keeping a special video,  so that if you just press a key manually, you will force the video to be saved without being automatically deleted when the card is full. Automatic emergency recoding video is the use of gravity sensor. It will automatically protect this video without being automatically covered and deleted during monitoring  a violent vibration on car, this function will be useful for vehicle collides.

Shielding measures

In order to decrease the cost o products, the copycat products always do not take any shielding measures and without strict test for their products, which will cause this products disturb some electronic products, such as GPS navigation  , remote control, audio, tire pressure meter, and driving computer, etc.

Whether purchasing with card

Driving recorder video with high definition picture,  always has a big volume up to hundreds MB per minute, so that there will be a strict request for reading speed of memory card, and  I advise driver purchase a superior card, because the slow speed card driving recorder is easy to be out of order.

AHD è l'acronimo di Analog High Definition, quindi una telecamera AHD è una telecamera analogica ad alta definizione, il segnale di trasmissione è il segnale analogico ad alta definizione. Parlando di alta definizione, in breve, di solito chiamiamo alta definizione i video con una risoluzione fisica superiore a 720p, indicati con l'acronimo HD.

La tecnologia AHD consente la trasmissione affidabile di segnali video ad alta definizione su lunghe distanze (500 metri) sulla linea di trasmissione analogica esistente. Adotta una tecnologia avanzata di separazione del segnale Y/C e di filtraggio simulato, in grado di ridurre efficacemente il rumore cromatico nell'area ad alta frequenza, con una migliore riducibilità dell'immagine. Rispetto ai tradizionali prodotti ad alta definizione, la qualità delle immagini delle telecamere AHD ha fatto un salto di qualità e un aggiornamento, con la massima nitidezza equivalente al livello HD 1080 full network.

Telecamera AHD caratteristiche e vantaggi:

• più nitida: separazione avanzata dei colori brillanti, filtraggio del segnale, tecnologia di riduzione del rumore 3D, maggiore nitidezza dell'immagine, migliore riducibilità dell'immagine; ;
• distanza di trasmissione: utilizzare una trasmissione coassiale, una linea ordinaria 75-5 può trasmettere fino a 500 metri;
• zero delay: dati acquisiti trasmessi al monitor senza codifica, in tempo reale e con alta fedeltà;
• compatibile: compatibile con D1/960H standard, compatibile con periferiche analogiche (inclusi distributore, matrice, ecc.);
• facile da usare: supporta la progettazione del menu OSD, impostabile a piacere;
• economico: prezzo normale per un prodotto di alta qualità;
• alta integrazione: prezzo del chip front-end AHD per prodotti di alta qualità;
• standard aperti: standard aperti a terzi, compatibili con i prodotti AHD di altri produttori, accelerano lo sviluppo del mercato.

La telecamera AHD segue il metodo di simulazione della trasmissione a definizione standard, che può ridurre la complessità di costruzione e implementazione, ridurre il costo dei materiali ausiliari e mantenere la complessità e i requisiti tecnici del personale addetto alla costruzione. È estremamente adatta per l'aggiornamento del vecchio sistema, è possibile passare facilmente dalla definizione standard all'alta definizione senza modificare il sistema originale. Inoltre, la qualità dell'alta definizione con il prezzo della definizione standard, rende la telecamera AHD molto versatile sia nel mercato civile che in quello industriale (come le telecamere AHD per auto).

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.

Risoluzione

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.

Impermeabile

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.

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.

Luview is willing to provide high quality customized dashboard camera for Mercedes Benz, BMW, Audi, GM, Ford, Cadillac and other vehicles. If you are looking for a reliable dashboard camera supplier /factory in China with competitive price, then you are come to the right place.
