Surveillance system with surveillance terminals and surveillance center
View Patent ↗A surveillance system having surveillance terminals and a surveillance center is configured to perform effective hazard alert signaling, depending on the hazard type. The surveillance system comprises a plurality of surveillance terminals, which are connected to the surveillance center by a network, carries out hazard and alert signaling. One surveillance terminal detects a hazard and sends a hazard information signal reporting what hazard has just been detected to the surveillance center. The surveillance center receives the hazard information signal, identifies what type of hazard source and the surveillance terminal that sent the hazard information signal, selects surveillance terminals to be alerted to the hazard from among the plurality of surveillance terminals, depending on the identified type of the hazard source and its locality, and sends a hazard alert signal to the selected surveillance terminals.
1. A surveillance system comprising a plurality of surveillance terminals and a surveillance center, the plurality of surveillance terminals being connected to the surveillance center by a network,
wherein one of said surveillance terminals detects a hazard and sends a hazard information signal reporting what hazard has just been detected to said surveillance center,
said surveillance center receives said hazard information signal, identifies a type of the hazard source and the surveillance terminal that sent the hazard information signal, and selects one surveillance mode that depends on the identified type of hazard source and its locality, and wherein said selected surveillance mode is to be sent to each surveillance terminal, and said selected surveillance mode is selected from among surveillance modes whereby a surveillance terminal sends video data of a view captured by its surveillance camera to the surveillance center,
said surveillance center sends a command indicating the one surveillance mode selected to the each surveillance terminal, and
wherein said surveillance center sends said hazard information signal to the selected ones of said plurality of surveillance terminals and a plurality of mobile terminals related to the selected surveillance terminals to alert over said network.
2. A surveillance system comprising a plurality of surveillance terminals and a surveillance center, the plurality of surveillance terminals located in a plurality of areas being connected to the surveillance center by a network,
wherein one of said surveillance terminals detects a hazard and sends a hazard information signal reporting what hazard has just been detected to said surveillance center,
said surveillance center receives said hazard information signal, identifies a type of hazard source and the surveillance terminal that sent the hazard information signal, selects areas to be alerted to the hazard from among a plurality of areas where said plurality of surveillance terminals are located, depending on the identified type of hazard source and its locality, sends a hazard alert signal to the surveillance terminals that are located in the selected areas, selects one surveillance mode that depends on the identified type of the hazard source and its locality, and wherein said selected surveillance mode is to be sent to each surveillance terminal, and said selected surveillance mode is selected from among surveillance modes whereby a surveillance terminal sends video data of a view captured by its surveillance camera to the surveillance center,
said surveillance center sends a command indicating the one surveillance mode selected to the each surveillance terminal according to the area in which the surveillance terminal falls is located, and
wherein said surveillance center sends said hazard information signal to the selected ones of said plurality of surveillance terminals and a plurality of mobile terminals related to the selected surveillance terminals to alert over said network.
3. A hazard and alert signaling method for use in a surveillance system where a plurality of surveillance terminals are connected to a surveillance center by a network,
said hazard and alert signaling method comprising a first process to be performed at one of said surveillance terminals and a second process to be performed at said surveillance center,
said first process comprising the steps of:
detecting a hazard; and
sending a hazard information signal to said surveillance center,
said second process comprising the steps of:
receiving said hazard information signal;
identifying a type of hazard source and the surveillance terminal that sent the hazard information signal;
selecting one surveillance mode that depends on the identified type of hazard source and its locality, and wherein said selected surveillance mode is to be sent to each surveillance terminal, and said selected surveillance mode is selected from among surveillance modes whereby a surveillance terminal sends video data of a view captured by its surveillance camera to the surveillance center; and
sending a command from said surveillance center indicating the one surveillance mode selected to the each surveillance terminal
wherein said surveillance center sends said hazard information signal to the selected ones of said plurality of surveillance terminals and a plurality of mobile terminals related to the selected surveillance terminals to alert over said network.
