It requires no power or data cables to set up and works for up to 40 days on a full charge to provide reliable protection even in the event of a power outage (EZVIZ Lab test result data in standard conditions, based on the use of 5 minutes per day).
2.4Ghz Wifi & Easy Installation: This surveillance camera only supports 2.4Ghz Wifi. The CB1 is a camera that leaves no cords to organize or drill holes to repair. Place it on a flat surface, clamp it to any metal surface in your garage or living room, or mount it to the ceiling for optimal coverage.
