We saw a phone similar to this not too long ago that monitored audio to detect home intrusion. The SecuPhone takes a slightly different approach by monitoring movement via a built-in motion detector. If it detects an intruder’s presence the phone dials a preprogrammed number that allows the user to listen in. Don’t want that burglar sticking around to burglarize your goods? Then just hit ‘1’ on the keypad and the device will emit a siren, or hit ‘*’ to activate the voice warning.
