Car DVRs and Dash Cams: Choosing a Camera and Accessories
Car DVRs (dash cams) record video while you drive and can provide important evidence in accidents, insurance claims and disputes. They also record incidents while parked if configured for parking mode. This category covers car DVRs and accessories such as mounts, power cables and memory cards.
Key features
- Video resolution: 1080p is the minimum for readable details; 2K and 4K improve number plate clarity.
- Night performance: sensors such as Sony STARVIS and wide apertures improve low-light recording.
- Field of view: 140 to 170 degrees covers multiple lanes without excessive distortion.
- Front and rear cameras: dual-channel systems record behind the car as well.
- G-sensor: detects collisions and locks the recording so it is not overwritten.
- Parking mode: records when motion or impact is detected while parked.
- GPS: records speed and location.
- Wi-Fi and app: allow viewing and downloading clips on a phone.
Power and parking mode
Most dash cams plug into the 12 V socket. For parking mode, a hardwire kit connects the camera to the car's fuse box and includes low-voltage protection to prevent battery drain. Professional installation is recommended if you are not familiar with car electrics.
Memory cards
Dash cams record continuously and overwrite old footage. Use high-endurance microSD cards designed for constant writing, and format them regularly. Ordinary cards can fail quickly.
Mounting
Mount the camera behind the rear-view mirror so it does not obstruct your view. Adhesive mounts are more stable than suction cups. Check local laws on windscreen mounting.
Legal considerations
Laws on dash cams and recording vary. In some countries, recording audio requires consent, and footage use may be restricted. Check local regulations.
Accessories
Accessories include hardwire kits, replacement mounts, extension cables for rear cameras, polarising filters to reduce windscreen reflections and memory cards.
Practical tips
- Check footage regularly to make sure the camera is recording.
- Use a CPL filter to reduce glare.
- Keep the windscreen clean.
- Update firmware for improved performance.
A reliable dash cam gives peace of mind and protection in the event of an accident.
