Physical security systems for protected facilities can be intended to: [2] [3] [4] deter potential intruders (e.g. warning signs, security lighting); detect intrusions, and identify, monitor and record intruders (e.g. security alarms, access control and CCTV systems);
The system is operated and aimed with a joystick and aiming screen. The device can be used for targets over 250 metres (820 ft) away, [14] and the beam has a power of 30 kilowatts. [55] The Los Angeles County Jail installed the smaller-sized unit, under the name Assault Intervention Device, on the ceiling of the Pitchess Detention Center in ...
Warning label for an electrostatic sensitive device, denoting the devices susceptibility to damage. A similar symbol without the bar and with a black "dome" denotes ESD-safe equipment. The human-body model (HBM) is the most commonly used model for characterizing the susceptibility of an electronic device to damage from electrostatic discharge ...
The Joint Land Attack Cruise Missile Defense Elevated Netted Sensor System, or JLENS (colloquially, Spy Balloon), [1] was a tethered aerial detection system designed to track boats, ground vehicles, [2] cruise missiles, manned and unmanned aircraft (airborne early warning and control), and other threats [specify].
Alerting devices indicate an alarm condition. Most commonly, these are bells, sirens, also and or flashing lights. Alerting devices serve the dual purpose of warning occupants of intrusion and potentially scaring off burglars. Keypads: Keypads are devices that function as the human-machine interface to the system. In addition to buttons ...
An electronic countermeasure (ECM) is an electrical or electronic device designed to trick or deceive radar, sonar, or other detection systems, like infrared (IR) or lasers. It may be used both offensively and defensively to deny targeting information to an enemy.
A fence-mounted perimeter intrusion detection system installed on a chain link fence. A perimeter intrusion detection system ( PIDS ) is a device or sensor that detects the presence of an intruder attempting to breach the physical perimeter of a property, building, or other secured area.
Equipped with a number of sensors, the vehicle is ideally suited for mine-clearing operations including detection, identification and destruction of improvised explosive devices (IED), landmines and other explosive materials. Development of the Husky 2G was prompted by the need to conduct longer missions and employ multiple detection systems.
