This Buying Guide will help you to invest on right Dash Cam Model and avoid spending money on any unwanted features. In this Dash Camera buying guide, we are explaining the essential features and least required hardware that must carry on a decent Car Dash Camera.
1. Dash Cam Auto Start and Stop
Auto Start and Stop is an essential feature of the Car Dash Camera. This feature is separating your cash dash camera from your smartphone or professional video shoot camera. Your Dash camera is coming with a power cable to connect to your car’s 12V cigarette lighter power source. This 12V socket will get power when you turn on your car ignition, and that will trigger dashcamera, which is already connected to the car’s power outlet. The Dash Camera will shut down when you turn off your ignition by sensing the power loss in cigarette lighter socket.
Few of these Dash Camera models have an internal backup battery that can offer some extra delay from one minute to five minutes to shut down your car dash camera after you turn off car ignition.
Note: There are car models with permanently powered Cigarette Lighter Sockets those may not support auto ON / OFF. In this case, the choices are, turn off Dash Cam manually every time or rewire an additional socket. There is a low battery protector (Sample Product with low voltage protection: Dash Cam Hardwire Kit, vary depends on dash camera model ) is coming for car dash camera, that cut off the dash camera power before your car battery drains out.
2. Dash Cam Loop Recording
This is another cool feature that you should aware of. Usually, the camera will record video on the memory card, and it will stop recording when the memory card is full. But, If your camera has the Loop Recording feature, then this feature let the camera to overwrite on the memory card on top of previously recorded videos. The advantage is, you don’t want to manually delete or format the memory card whenever it gets full.
This is an essential feature makes sure your camera will record each and every instant while you are on the road even the memory card reaches full capacity. The downside of this feature is that you have to move videos from your memory card to computer if you want to save those for the future before the Dash Cam overwrites on it.
3. Dash Cam Memory Card
The dash cam memory cards wear out faster than any other camera. Dashcams are constantly writing on the memory card, all the time while you driving. When you select the max memory, refer dashcam spec for the max size support.

Technically, both Micro SD Card and Trans Flash (TF) Cards are same. So what would be the ideal storage size? It depends on how long you are traveling per day and the video recording resolution.

A Dash Camera which is recording 1080p video at 30 frames/sec into AVI format needs at least 400MB of storage space for 3 minutes long video. 8 GB memory card can hold 20 minutes video with 1080p in AVI format. We recommend 16GB SDHC and set your recording resolution to 720p.
You can get 80 minutes of video footage with your 16GB memory card if you select a 720p resolution. The 720p resolution offers a decent clarity video, good enough to record road signs, name boards, and car number plates. When you buy SDHC cards to record videos, go for at least class 6 and above, better to have class 10 SDHC card to make sure the card supports the read / write speed for the Dash Cam.
4. Car Dash Cam Resolution
HD recording is very common in video shooting cameras. Most of the Dash Cameras are coming with an ability to record video up to 1080p HD, 30 frames per second. A Car Dash Camera with 1080p resolution can carry more than enough details that can capture car number plate, street lights, and road symbols in detail.
I set my dash camera in 720p resolution, and it is good enough to read the street names and number plates from my video footage. When you buy dash camera, go for 1080p because there is not much difference in price between 720p and 1080p Dash Cameras.
5. Car Dash Cam Recording Angle
Recording angle is coming 120 degrees by default for the most of the dash cameras. Wide angle recording camera means that can cover more street area on both sides while you drive. There are dash cameras available like TaoTronics Dash Camera, and those are offering 150 degrees and AUKEY Dash Cam (Amazon $69.99) is built with 170 degrees wide angle lens.
