Power is described as USB-C or 8–24 V wiring, while the specifications also state that batteries are required and give 3.6 Volts. Check the selected listing and intended setup for these details.

## Customer feedback

The supplied evidence contains aggregate ratings but no written customer feedback, so it does not establish what buyers praised or criticised. The overall rating is favourable, though a small lower-star share means experiences are not uniformly positive. Ratings alone cannot indicate how the camera, storage or power arrangement performed for individual buyers.
