Usage Scenario
Branch Modem and Security Camera Continuity
Centrally monitor the modem, NVR and camera network in multiple branches without opening ports.
- • Ping Watchdog
- • Controlled modem reset
- • Branch-based MQTT
- • Central alarm
Central monitoring without port forwarding
The NetRelay hub at each branch connects outward to the MQTT broker. Modem, NVR or camera IPs can be monitored with Ping Watchdog and outage events can be sent to the center.
Secure reset policy
Consecutive failed checks, waiting period and daily repeat limit should be defined. The effect of a sudden power outage on disk-using devices such as NVR should be evaluated according to the manufacturer's instructions.
