Not on its own. The cameras, the DVR or NVR and the router all need power. During a cut they keep working only if they are connected to a UPS, an inverter or a solar system with batteries. Without that, recording stops when the supply goes and starts again when it comes back, leaving a gap in the footage.

A UPS switches over almost instantly, but a typical unit runs for minutes rather than hours. A house inverter with large batteries runs much longer and is what most village homes rely on for long cuts. Many people connect the CCTV to the inverter and, if the recorder restarts when the inverter takes over, add a small UPS for the recorder and router.

It depends on the battery capacity, its age and condition, how many cameras you have and what else is on the inverter. A few cameras, a recorder and a router usually draw much less than a cooler or several fans, so the CCTV adds a modest load. At the survey we list that load so you can judge it against your inverter.

Yes, in two ways. If the house has rooftop solar with batteries, the CCTV can be put on its backed-up output. For a spot with no supply at all, such as a field gate or tubewell room, a camera with its own solar panel and battery that sends video over a 4G SIM is an option, though it needs a sunny mounting spot and a mobile signal there.

Footage already written to the hard disk normally stays, but a sudden cut interrupts recording, and repeated hard shutdowns are not good for the disk over time. Putting the recorder on a UPS or inverter avoids sudden shutdowns, which is one reason we plan the backup with the cameras.

Only if the router, and the internet connection's own equipment, are also on backup. If they are, live view keeps working; if not, the recorder may keep recording locally but your phone shows the cameras as offline until power returns. If the house needs internet, ask about our WiFi broadband in Khudan.
