Are there other types of WatchDogs?

One is a six digital input WatchDog. . . it is particularly useful for building security systems. Up to six inputs (door switches, motion detectors, fire alarms, etc.) can be connected to this single WatchDog, and of course these devices show up on the computer screen that is running the KENTROL ALARM software via the LAN. The second is a WatchDog that is used to check the sanity of the host computer.
