Dash Cams
Dash cams, also called dashboard cameras or dashboard cams, are cameras that record video in a vehicle. Footage can be taken incar while driving or when the car is parked and stationary. They are a type of incar CCTV. They are typically mounted inside the car pointing out of the front windscreen. Some models can be used as a rear-facing camera for a rear-view of the road.
Why do I need a dash cam?
Dash cams can be used to record scenery, but most dash cams are installed incar as a digital eye witness to be used as evidence in the event of an accident, crash or collision. Dash cams can sometimes be used to help with insurance claims. Dash cams encourage some drivers to drive more carefully which may help to improve their safety and the safety of other road users.
Do I need a memory card?
It can vary by model, but most dash cams will have no integrated memory or a very limited built-in memory. Use of an external memory card (usually an SD card) will allow you to record for longer.
What is loop recording?
Many dash cams use loop recording. Footage is recorded in segments that are between 1 and 5 minutes long. When space runs out on the memory card, older video clips are overwritten with the latest footage. Loop recording ensures that you never run out of memory.
Loop recording can make it easier to download and share footage as it is already segmented. Many dash cams have an integrated system to detect collisions, such as G-force sensors. In the event of a collision, the dash cam will save the video file so that it is not overwritten.
What should I consider when choosing the right dash cam?
Set up: Most dash cams are installed in the vehicle with a suction cup that can easily be removed for use across multiple vehicles. Some models are affixed with more permanent measures such as double-sided tape.
Power: Dash cams are typically powered by a 12 V cigarette lighter socket, but some cameras can be hardwired to your in-car electronics.
Resolution: The video resolution varies by model. Full HD 1080p footage will capture more detail and record a sharper video than a 720p HD version.
Lens: Wide angled lenses will capture a wider view of the road.
Light conditions: Some dash cams have night vision which is suitable for night driving and low light conditions.
