How To Choose A Professional Car Camera
Car Cameras, an emerging product of car accessories industry since 2009, sometimes they are called Dash Camera, Car DVR, Carcam, Vehicle Video Recorder and Vehicle Black Box, etc. It is the device which airplane blackbox technology used on vehicles. Most car cameras record both the video and audio to a Micro SD card which is similar to what we used for a digital camera. Usually car cameras are mounted on the windshield or behind the rear view mirror if the car camera is small enough.
Just because of the importance and benefits of a car camera, many governments insist on installing a professional car camera for all vehicles like taxis private cars, school buses, and official vehicles, etc. In some countries, the popularizing rate reaches up to 80%, Russia for example. The US and EU governments have also requested all vehicles to be equipped with a car dash camera since 2010.
Surveying the global markets, car cameras are primarily from China and Korea, and the Chinese brand occupied 75% of the global markets. S.WILL is a well-known manufacturer of car camera. There are thousands of car camera suppliers on the market right now, the quality and service varies greatly. How to choose a quality car camera is often difficult for those who are not familiar with this industry. Here is what you should look for:
For a video camera, no doubt we care the video quality mostly, car camera is no exception. Currently the HD720P and HD1080P are the mainstreams on the market; however, there is also a cheaper one of VGA resolution. However, if you pay less to get a non-HD car camera, you’ll likely to be disappointed on the video quality; some sellers are not honest about this.
Currently all the car camera manufacturers primarily adopts MPEG-4 and H.264 compression method, of course H.264 compression is very advanced, the car camera might perform differently if different resolutions are adopted. While choosing your own car camera, be certain to get full real-time without frame leakage.
Choose a wide viewing angle one, some manufacturers greatly exaggerated their viewing angle. Currently the widest viewing angle we see in the market is 140 degrees.
Loop recording function is also very important as we know that generally all car cameras store the video/audio footage in MicroSD card or SDHC cards which has very limited storage space. Generally, a 32G SD card can record about 8 hours in HD720P format, even shorter if in HD1080P, for this reason, supporting loop recording is particularly important.
Some car cameras come with infrared LEDs which was supposed to fill flash when in low light surrounding, however, LEDs are not powerful enough to improve the night recording. Many vendors treat it as a good selling point – just disregard it.
Besides the above mentioned, we should also take attention to some other features such as Continuously G Force Sensor, GPS navigation, Power Protection, Auto ON/OFF etc.
