IP WatchDog2 Lite

In a user-defined period, the IP WatchDog2 Lite detects the status of internet connection and LAN connected devices. IP WatchDog2 Lite monitors the availability of up to 10 devices and can reset one or two physical devices (two output channels).

In case the internet connection or any monitored device stops responding the IP WatchDog2 Lite can restart up to two connected devices via its AC 50V/0,5A (DC 30V/1A) relay DO.

A restart of each output channel can be realized also manually from the main page (under password).

A built-in web server is used for configuring.

4 methods of device failure detection:

  • Ping Out: IP WatchDog2 periodically sends PING requests
  • Ping In: IP WatchDog2 waits for a PING from the monitored device
  • Web client: IP WatchDog2 monitors the accessibility of a web page
  • Web server: IP WatchDog2 waits for a request for its internal WEB page
  • 10x Monitoring Channel on LAN
  • 2x Relay Output AC 50V/0,5A (DC 30V/1A)

  • A change of monitored device status sends an alert by e-mail, SMS, SNMP Trap, or activates DO relay and a sound alarm.
