Dash camera buying: channels, power, storage and privacy
Choose a dash camera around coverage and installation constraints rather than resolution alone.
Decide which views matter before comparing headline resolution. A single-channel camera such as VIOFO VS1 Mini focuses on the forward view; BlackVue ELITE 10-2CH is a two-channel listing. Extra channels add cameras, cables, mounting positions and storage demand. Check what is included because bundles and regional versions can differ.
Review memory-card requirements, recording modes, app compatibility and file access. Estimate how quickly the chosen settings overwrite footage. If you need parking recording, confirm the required power accessory and the vehicle’s battery-management constraints. Route cables outside airbag paths and keep all hardware beyond the driver’s critical view.
Recording laws vary. Passengers, employees and people outside the vehicle may have privacy or audio-recording rights. Learn the rules where the camera will be used, secure account access and erase footage you no longer need. A camera can preserve a file; it cannot establish the complete context of an event by itself.
