Dash cam buying guide: features that matter
A dash cam should capture useful footage reliably, not just advertise a high resolution number.
Prioritize readable footage
Look for sample recordings in daylight and at night. Resolution, lens quality, exposure control and compression all affect whether license plates and road details remain legible.
Decide on front-only or front-and-rear coverage
A front camera covers what happens ahead. A rear camera adds context for rear-end incidents and parking situations, but requires extra wiring and storage.
Plan for heat and power
Cars can get extremely hot. Check the manufacturer’s operating-temperature specification and whether the camera uses a capacitor or battery. Parking-mode recording may require a compatible hardwire kit and low-voltage cutoff.
Budget for storage
Use the endurance-rated memory card recommended by the camera maker. Loop recording continuously rewrites footage, so card endurance and supported capacity matter.
Consider the everyday experience
Look at app stability, file retrieval, clear event-locking behavior, mounting position and whether the camera obstructs your view. Confirm local rules before installation.
