Car Dash Cameras are supposed to capture live videos while you drive. Dash Cam recorded visuals might be a piece of crucial legal evidence to protect you in an unfortunate accident or from insurance fraud. Sometimes you will be lucky enough to capture rare footage on your cam that can be viral on YouTube and other social media.

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.

Must Read: Don’t Waste Money on these Dash Camera Optional Features unless it is required for you.

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 the dash camera, 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 a 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 that 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 is coming for a car dash camera, that cut off the dash camera power before your car battery drains out. The hardware kit pin type and voltage mary vary camera by camera, always buy the hardware kit compatible with your dash camera.

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 lets the camera 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 that 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 the computer if you want to save those for the future before the Dash Cam overwrites on it. The loop recording interval can be set to 1min, 2 min, 3min, 5min depends on the camera model.

Memory Card (TF Card for Dashcam)

The dashcam 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. The Dash Cameras in the market is supporting up to 128 GB Micro SDHC.

The Rexing V1 2.4s supports up to 128 GB memory card. You may see the TF Card in the specification of Car Dash Camera. Technically, both Micro SD Card and Trans Flash (TF) Cards are the same. So what would be the ideal storage size? It depends on how long you are traveling per day and the video recording resolution.

SanDisk High Endurance cards are developed for high endurance applications and ideal for dashcams and home video monitoring cameras. This card also tested in harsh conditions and temperature-proof and shock-proof for dashcam use. Transcend High Endurance is the next choice, and costlier than Sandisk.

This SD Card specially developed for high endurance applications, that support long hours of video recordings and playbacks. Lexar High-Performance (Amazon link) is the highly durable solution for dash cam owners. This SD card makes sure up to 95MB/s (633x) transfer speed, and stores more than 36 hours of HD video. This SD card is verified compatible with GoPro cameras (32GB-256GB).

If you don’t care much about loss video footage, then there are some budget solution SD cards. You can buy a SanDisk Ultra 16 GB MicroSDHC Class 10 Memory Card for less than $11.00 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 dashcam support, then go for a Class 10, 64GB Micro SD Card and this Samsung Evo Select 64GB Micro SDXC card cost around $23.00 from Amazon with Class 10 UHS 3 speed and high-performance for up to 4K UHD video recording. For those who want more memory card selection for Dash Cams, please visit Memory Card Buying Guide-Choose Right Memory Card for Camera&Gadgets.

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.

Dashcam Recording 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 a dash camera, go for 1080p because there is not much difference in price between 720p and 1080p Dash Cameras.

Recording Angle

The recording angle is coming 120 degrees by default for 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.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.

In Russia, Dash Cams are very common, and you may see some amazing footage captured by the Russian drivers while they were driving. You can capture the entire pleasure trip of the next vacation ride with a decent dash camera with a 32GB or 64GB size memory card.

Remember, you can’t compare these dash cams with your professional video camera or smartphone camera. These cameras are built to capture the video while you drive your car at any speed without any distortion. We are listing here the essential features of a Car Dash Camera.

Dash cams are coming at an affordable price that varies from $20 to $300 range based on the hardware and software features. These dash cams can automatically record live videos as long as you are on the road. It is crucial to select the right camera with the right specification and features based on your requirements and budget.

This Buying Guide will help you to invest in the right Dash Cam Model and avoid spending money on any unwanted features.


  1. Great info but math seems wrong on the recording time. Considering 3 minutes of 1080p video takes up 400MB, 8GB memory card will hold about 60 minutes of footage, not 20 minutes. Also 16GB memory card will hold about 4 hours of footage, not 80 minutes.
