A surveillance device includes: an electrical power supply system configured to be connected directly to an electrical mains system, a communication system configured to communicate with an operating center and/or with user devices, occupancy sensors configured to detect an intrusion in a surveillance area where the surveillance system is installed, cameras configured to record images in the surveillance area, an alarm configured to generate an acoustic and/or luminous alarm; and a control unit connected to the electrical power supply system, communication system, occupancy sensors, cameras and alarm.

Doorbell camera systems are provided that can include a doorbell camera subsystem and a chime subsystem. The doorbell camera subsystem may include, among other features, a camera module and a doorbell button. The chime subsystem may include, among other features, a battery and electronics that interface with a chime such as existing doorbell chime or a speaker. The battery is co-located with the chime subsystem and away from the doorbell camera subsystem. Co-locating the battery with the chime subsystem removes the battery from potentially harsh environmental conditions it would otherwise be subjected to if it was co-located with the doorbell camera subsystem.

A meter socket with a tamper detection assembly is disclosed. The tamper detection assembly may include a light sensor that enables the detection of tampering caused by an energy thief removing the cover of the meter socket enclosure and/or removing the meter from the meter socket in an effort to access the power supply connectors and steal electricity. The tamper detection assembly may also include an acoustic sensor that enables the detection of tampering caused by an energy thief drilling, cutting, hammering, bending or otherwise attempting to violate the integrity of the meter socket enclosure in an effort to access the power supply connectors and steal electricity. The tamper detection assembly is preferably mounted within a mounting block of the meter socket so as to provide a secure source of power and communications for the assembly.

To provide an auxiliary unit capable of reducing the number of signal lines for outputting warning information. A multi-output unit is connected to a plurality of sensor units via individual output lines 262a to 262h through which the plurality of sensor units output a detection result of each of the plurality of sensor units and a data line 261a for communicating with the plurality of sensor units. The communication control unit 104 communicates with each of the plurality of sensor units via the data line 261a and receives warning information transmitted by at least one of the plurality of sensor units. When receiving the warning information from at least one of the plurality of sensor units via the data line 261a, the common signal line 154 outputs a common output signal indicating the warning information to an external device.

The disclosure describes a system for monitoring and mitigating damage to electrical utility structures and the surrounding environment. In some embodiments, the system includes fire boxes, arc sensors, angle switches, and disconnect switches configured to generate alert signals when a hazard is detected. In some embodiments, the system includes cameras configured to detect a hazard such as a fire or moving object. In some embodiments, the system includes light transmitters and light receivers positioned at a predetermined location away from power lines to detect objects that interrupt a line of site. In some embodiments, the system can electrically isolate a power line before a detected hazard impacts a power line.
