Direct answer
Some functions can continue if they are designed for the particular failure. A local recorder and wired cameras can keep recording through an internet outage while the local network and power remain available. Cloud-only recording, remote viewing, push alerts, and app control may stop. A security panel with cellular backup may still transmit eligible alarm signals when its backup service is active.
Power loss affects cameras, routers, switches, recorders, controllers, and displays. A panel battery may run alarm functions for a limited period, while video requires a correctly sized UPS or generator-backed circuit. Test internet loss, AC loss, low battery, switch failure, and restoration. “Battery backup” should never be assumed to cover every component or an unlimited period.
