In a user-defined period, the IP WatchDog2 Lite detects the status of internet connection and LAN-connected devices. The IP WatchDog2 Lite can monitor up to ten 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.

When the status of any of the monitored channels changes, the IP WatchDog2 Lite can send a notification directly as SNMP Trap as well as Email to two addresses or indirectly through the HWg-SMS-GW3 gateway in the same LAN as an SMS or a Ring to one phone number.

A built-in web server is used for configuration. The device can be monitored remotely over the internet using the free SensDesk portal in combination with the SensDesk Mobile application for iOS and Android. It works with HWg-PDMS and HWg-Trigger.

The IP WatchDog2 Lite uses the following four methods of status 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)
  • 1x SNMP Trap; 2x E-mail; 1x “SMS+Ring” (via external GSM gateway)
  • A change of monitored device status sends an alert by e-mail, SMS, SNMP Trap, or activates DO relay and a sound alarm.
  • Connected via LAN. Configuration via the built-in web server.
  • For Ring or SMS alarms, use the HWg-SMS-GW3 gateway in the same LAN.
  • Data logger for up to 200 records. With the HWg-PDMS software logged data can be exported to MS Excel.
  • Compatible with a range of third-party SWs (SCADA, etc.). Examples for programmers using the product are available in the HWg-SDK (Borland C++, MS Visual, VB, C#, PHP, Java, and more).
