An electric fence is a security system that uses short electric shocks to prevent intruders from entering a property. It is commonly used in homes, estates, farms, and schools for protection.
It works by sending electric pulses through wires; anyone who touches it receives a brief shock that discourages entry. The system includes an energizer, wires, posts, and a grounding unit, and can be combined with alarms or CCTV.
Electric fences are widely used in places like Lagos for added security against theft and trespassing.
