Car dashcam is a kind of camera that you install in your car for many reasons. It can be mounted inside your car, usually on the front windshield.
It will be a silent witness for you in incidents that you will be able to save footages of what really happened in a certain scenario whatever you're in while you're driving or while your car is parked. Car dashcams have saved people a lot of money and have also helped in lowering insurance premiums.
All dashcams have pros and cons, and it's hard to say whether one is better than another because it depends on what you need. Here are the most important considerations to make.
At minimum, you'll want HD 720p recording(most of dashcams on sport-cameras.com higher than 720p). This ensures that footage is sharp enough to make out license plates, car makes and models, and faces. HD 1080p and 4K resolution dashcams are available too, but higher resolution video means larger video files.
At minimum, aim for 64GB of storage. The higher the dashcam's resolution, the more storage capacity you'll need to record the same amount of footage. An hour of 720p footage might be 1 to 2GB whereas an hour of 1080p footage might be upwards of 6GB.
Night vision is crucial because you never know when an accident might occur. Headlights, city lights, and street lights can sometimes provide enough illumination that night vision isn't necessary — but those lights won't always be there. Don't risk it.
Some dashcams have the ability to turn on with the car engine and turn off when the car engine shuts off. It's a must-have feature because dashcams are only useful when they're on — and according to Murphy's Law, the one time you forget to turn it on will be the day you have an accident. Don't risk it.
All view obstructions are dangerous when driving a car, so avoid large dashcams that may block line of sight. This is critical if you already have other potential obstructions, like a dangling air freshener. In general, smaller is safer.
When a dashcam's storage fills up, two things can happen: it stops recording, or it loops back and records over the oldest footage. The former prevents you from overriding crucial footage that you forgot to transfer out, but can leave you vulnerable if it stops recording in the middle of a long drive. Loop recording is less risky.
Some dashcams detect accidents, then automatically save footage starting from several minutes before impact. Some can also automatically turn on when an impact is detected, even if the dashcam was off, which comes in handy when parked.
Front and Back Camera
If you want full coverage, a front-facing dashcam won't be enough. What happens if you get rear-ended? A front-facing dashcam can provide some evidence, but won't capture the whole incident. Some dashcams come in pairs, the second one mounting to the rear windshield.
While most dashcam models come with mount accessories, a few don't. These are most likely designed to place on your dashboard or on the windshield, but if the idea of that doesn't sit well with you, you can always grab a universal dashcam mount separately.
