What is video verification of an alarm and why is it needed?

When a sensor is triggered, the concentrator requests an image from the nearest PIR camera or IPC, and the operator sees the real picture — whether it is an intruder or an accidental trigger.

Does the system work when the internet goes down?

Yes, the concentrator supports two communication channels — 4G and Wi-Fi, and automatically switches to the other if one fails.

Can the system be controlled remotely via a smartphone?

Yes, Dahua provides a mobile application for remote control, viewing status and receiving push notifications about alarms.
