Collection of household anti-theft alarms

Anti-theft host function and working mode

The host is the core of the system. It is used to receive the alarm signal from the detector and provide timely feedback; after receiving the alarm signal, the host will generate a high-decibel siren, and will dial out multiple sets of alarms set by the owner himself through the telecommunications network. phone.


Alarm receiving and processing host

The alarm receiving and processing host is also called anti-theft host. It is the hub of the alarm probe. It is responsible for receiving the alarm signal, controlling the delay time, and driving the alarm output. It combines all the anti-theft and anti-intrusion sensors in a certain area to form an anti-theft tube area. Once an alarm occurs, the area can be clearly reflected on the anti-theft host. The anti-theft host is currently dominated by multi-circuit partition protection. Depending on the size of the system, the maximum number of defense zones is 2 to 100 circuits. The superior system can also show which alarm sensor and location of the alarm source in the area to facilitate Corresponding police response countermeasures. Modern anti-theft hosts are controlled by microprocessors, with read-only memory and digital display devices, which are generally programmable and have high intelligence. The main performances are:

1. The alarm is displayed by sound and light, and the alarm can be released manually or by delay.

2. The connected anti-theft and anti-intrusion sensors can be set to the armed state or the disarmed state according to the need, and the control method and the defense loop performance can also be programmed.

3. Multiple groups of password keyboards can be connected, and multiple support passwords can be set for confidentiality and anti-theft.

4. In the event of an alarm, the alarm signal can be forwarded to a higher-level department or security company via a communication line in an automatic or manual intervention to quickly communicate information or network.

5. The alarm linkage action can be set by program, that is, when there is an alarm, the programming output end of the anti-theft host can execute the corresponding action through the relay contact closure.

6. The telephone dialer is the same as the siren and the alarm light. It is an alarm output device. The difference is that the alarm light and the siren output sound and light. The telephone dialer transmits the pre-recorded sound information to a person or A unit.

The high-end anti-theft host has a linkage device with CCTV surveillance cameras. Once an alarm occurs in the system, the camera image of the alarm area will be immediately displayed in the central control room, and the alarm time, alarm image, camera Information such as numbers is recorded in real time. If it is a system connected to a computer, it can be stored in the form of an alarm information database to facilitate quick and easy retrieval and analysis.
