Tips for Choosing Car Dash Camera

There are several basic features of a vehicle recorder: take photos, delay power off, motiondetection, and G-sensor. Car Dash camera is not only a video recorder but also a camera. Mainstream products have the shooting feature of 10MP camera. Normally, the higher the pixel is, theclearer the details are. A higher pixel cam will take the license plate and colliding parts clearer. Itnow can realize the recording of automatic. You can set it turning on while started and off whilestop. However, we may get encounter into some sudden accidents while stop the car, so we needthe function of delay power off. Several seconds or minutes will be enough.

Compared with the previous two, the motion detection is not as necessary, yet sometimes it hasspecial purpose. The principle is not complicated: when we parking in the lot or other places, therecorder will get into the status of standby for the reason of image static. If the scene is changing,the cam will start to record. This function is aiming to avoid the vandalism. There are two fataldisadvantages: not suitable for crowd places and power supply. Recommend to turn off thisfunction.

G-sensor is important to avoid the content loss of accidents. If there are crashed or otherweightlessness conditions, the recorded video will be locked. Even if you don’t check the data fora long time, the locked video will not be covered.

High pixel is not all feature of a cam. For instance, the data of iPhone 5S is only 8MP, but itobvious that all dash cams can’t get the effect of iPhone. The biggest parameter that related to theimage quality is the sensor. There are two types in the current market: CCD and CMOS. CCD isbetter but also more expensive and power consumption. In fact, CMOS dash cams are enough forthe majority conditions.

Voice recording is useless but may also harm to your privacy. Even you purchase one car DVRwith G-sensor and voice recording. I’d like to recommend you to turn it off.
