Patent ID: 8032110

Claim:
A mobile security device comprising: a microprocessor-based main unit having an image capturing member, a heat-sensing motion detection member, and a control circuit electrically and signally connected to said image capturing member and said heat-sensing motion detection member, said control unit having a microprocessor, a memory and a radio transceiver member, said radio transceiver member being capable of conducting two-way, real-time and message-based communications via a mobile communication network, said radio transceiver member having a SIM card and having a mobile number assigned to said SIM card; an infrared camera signally connected to said control circuit of said main unit and capable of sending captured images to said control circuit; a smoke detector signally connected to said control circuit, said smoke detector triggering said control circuit when sensing smokes; and a heat-sensing motion detector signally connected to said control circuit, said heat-sensing motion detector triggering said control circuit when sensing presence of a warm object; a remote controller capable of interacting with said control circuit; wherein when said smoke detector senses smokes, said heat-sensing motion detection member or said heat-sensing motion detector detects body heat of an intruder, said image capturing member or said infrared camera which detects object moving by comparing captured images will double confirm whether there is smokes or an intruder, then said control circuit is triggered to make phone calls by automatically dialing repeatedly a present number stored in said control circuit via said radio transceiver member and a mobile communication network, and when said phone calls are answered, said control circuit will play a pre-recorded voice message stored in said control circuit to an answered party to report detected abnormality; if called party is answered with a cellular phone with video playing capability, said control circuit will send captured images or video clips by said image capturing member of said infrared camera to said cellular phone for display in real-time so that the called party can see what has happened in monitored environment, and the captured image will be simultaneously sent to a preset email box which email address is stored in said control circuit; wherein when a user makes a call by dialing said mobile number or, or send a SMS or MMS message to said mobile number, said control circuit will verify to see if calling number matches a preset authorization number stored in said control circuit; if said user is authenticated, said control circuit will hang up said call and send captured images or video clips to designated destination thereby reporting current situation of said monitored environment.
