- Does it really record three views at once?
- Yes. It records the road ahead, the cabin and the rear at the same time, so one unit covers what a single- or dual-channel cam misses.
- What resolution do the rear and cabin cameras record?
- The front camera reaches 4K. The cabin and rear channels record at lower resolution, which is normal for three-channel cams and still enough to read faces and plates up close.
- How is it installed?
- The main unit mounts on the windshield and plugs into power. The rear camera needs a cable routed to the back of the car, which is the slowest part of the job.
- Does it work with a phone?
- Yes. Built-in Wi-Fi connects to a phone app for live view and downloading clips, so you do not have to remove the card.
- What size memory card does it need?
- Use a high-endurance microSD card. Recording three channels at high resolution fills cards quickly, so choose a large one and reformat it regularly.
- Is it good at night?
- Night shot helps, and the front camera performs best. Cabin and rear footage is grainier in very dark conditions.
- Where is the 3 Channel Dash Cam 3.2" 2K/DUAL 4K cheapest?
- At Newegg, for $171.99, as of our latest check.
