I. The necessity of installing an Electronic Fence in a prison:
As a highly dangerous and highly serious place, and because the inmates under its internal supervision are special, their potential threat to society must absolutely not be ignored. Therefore, the security system used in prisons is more specialized than in other fields.
II. Common drawbacks of prisons without Electronic Fences:
1. Violent offenders are increasing, and the factors threatening the safety of officers are growing. In a society in transition, violent cases such as robberies, gang crimes and organized crime are on the rise, and violent offenders in prisons remain high, increasing the factors threatening officers' personal safety.
2. Insufficient or aging prison protection equipment. If visual monitoring equipment is installed comprehensively, the inmates' every move is under the officers' monitoring; then, once an attack on officers occurs, officers can be dispatched en masse to control the situation. In this way, officers would not lose their lives at the hands of a single inmate!
3. Officers are complacent and not alert enough. Prison officers live with inmates year-round and can easily become complacent, especially relaxing their vigilance toward those criminals who pretend to be cooperative. If the on-duty officers are highly alert and assign officers to track key inmates, vicious incidents may be avoided.
4. Other uncertain factors.
III. Advantages of installing an Electronic Fence in a prison:
The Electronic Fence has a deterrent function: the high-voltage fence and warning signs exert a strong psychological deterrent on intruders, preventing them from committing crimes;
The Electronic Fence offers strong active protection: when an intruder breaks in, they receive an effective electric shock that stops their unlawful behavior;
The Electronic Fence provides comprehensive protection with no blind spots: the installation of the front-end fence is unaffected by the length, size or terrain of the perimeter, and it is easy to install without dead corners. It can also be installed on the ground for full protection and to eliminate blind spots;
The Electronic Fence has a low false-alarm rate and works around the clock: its intelligent alarm delay function greatly reduces false alarms. It can still operate normally in the presence of small animals, tree branches and severe weather, with a low false-alarm rate, greatly reducing unnecessary patrol dispatches;
The Electronic Fence can be networked with security and IT systems: through RS485 cabling it can easily link with other security products and be quickly networked, greatly improving the security and intelligence of the security system;
The Electronic Fence allows remote operation: the host can be controlled via a keypad, software or LAN, conveniently and quickly.
