Digia ImageSpy for Nokia 7650 and 3650
Digia ImageSpy is an innovative application for camera and MMS enabled Nokia 7650/3650 devices. Now the camera can be set to monitor its neighbourhood and raise an alarm when motion is detected. The alarm can be silent, when picture is taken, message (MMS/SMS) is sent or call initiated to predefined address. The alarm can also be set to play user selected sound files. Repeated alarms and delays before and after alarm are supported, so the application can survey its target by recording and reporting any new motion detected for longer period.
FUN
Surprise your friends or colleagues; make your 7650/3650 to play your favourite sound file whenever they enter to your room. Take a snapshot of Santa Claus when he steps out from the chimney. Have a peek of stranger, who has borrowed the stuff from the refrigerator or wine cellar recently. Now you can see how late it really was when your partner arrived from last night's party. Play hide and seek -children and pets just love this application.
PROTECTION
Sleep well and tight all night long. Have your main entrance, backyard or vehicle guarded and get informed when something unexceptional occurs. By using application specific code you can deactivate alarm before the alarm is raised, similar way as provided by ordinary security systems.
SURVEILLANCE
