We are listing here the essential features of a Car Dash Camera. There are several Optional features like Car Dash Camera Battery type, display type you don’t want to worry much. Be careful, don’t Waste Money for these Dash Camera Optional Features unless it is required for you.

In this Dash Camera buying guide, we are describing the essential features and least required hardware that should carry a decent Car Dash Camera. This Buying guide will help you to invest on right Dash Cam Model and avoid spending money for any unwanted features.

1. Dash Cam Auto Start and Stop

Auto Start and Stop is an essential feature for 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 into 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 dash camera, which is already connected to car’s power socket. 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 has 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. The other (not recommended) choice is to leave Dash Cam there and the Cam will turn off when internal battery run out of juice.

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 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 every time when 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 Cameras currently in the market are supporting up to 128 GB Micro SDHC (Rexing V1 2.4 supports up to 128GB memory card). You may see TF Card in the specification of Car Dash camera. 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.

You can buy a SanDisk Ultra 16 GB MicroSDHC Class 10 Memory Card for less than $9.00 from Amazon. If you are looking for more recording time or high-resolution video, then go for 32 GB, Samsung EVO 32GB Class 10 Micro SDHC Card with Adapter is coming for a price less than $11.00 from Amazon. If you can afford, and your dash cam support, then go for a Class 10, 64GB Micro SD Card and this Samsung Evo Plus 64 GB Micro SDXC card cost around $23.00 from Amazon with 10000 Mating Cycles.

A Dash Camera which is recording 1080p video at 30 frames/sec into AVI format needs at least 400MB of storage space for a 3 minutes length 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. 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 support 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, those are offering 150 degrees and up recording angle.dash cam view angle Featured & Image credit: TaoTronics Amazon Store

Advanced cameras have a wider view, offering 160 to 180 degrees of recording angle. For example, Rexing V1 Dash Cam is offering 170 degrees with 6-layers glass lens capable of catching almost every minute details on the road.

  1. I have own/owned 4 different brands of dash cams. They all work, but just get better with the image clarity. My CHALLENGE is that regardless of what dash cam brand, when I have to do a hard braking (accident) the dash cam records great right up to that hard break/accident segment. The dash cams are designed to lock these segments so that they are not erased or recorded over. My Challenge Issue is How To Open These Locked Segments and be able to do a Playback on the Locked Segments.

  2. I have had no luck with dash cams I cant get them to stay on could someone please advise me re what I should set camera on when I start car camera starts but shortly after it turns itself off

    • @Neville
      Did you check your power supply? Please try a phone charger and ake sure it is continuously working. If you think the charger is good, then check with the dash cam, try to format the memory card from dashcam itself. Also, please make sure your dashcam is not over-heating. These would be the first step in rectifying the issue.

  3. Recently I’ve purchased by recommendations – VIOFO A119. It is good car dashboard camera with GPS and CPL filter. It records wide view angle (170 degrees) and has high HD quality.

  4. Allways wanted to have dash cam to record my driving. I have gotten tickies, had now way to prove to the court, what happen. I can now show the court that the police is lieing.

  5. Do NOT NOT NOT use San Disc Ultra – Many say very unreliable in dash cam; even San Disc say NO use their “high endurance” otherwise not guaranteed.
