Energizers used for commercial and industrial uses

Electric fences at large properties where a high level of security is required, has to be zoned. In case of an alarm, the armed response have to have some kind of indication of the location of the problem.

Keep in mind that in the event of a short, the whole fence is at risk if only one energizer is used. That is the reason why Tandem Security Systems prefers to rather install one powerful energizer per zone and monitor it remotely.

Stinger electric fencing will have a security solution to suit your needs

We all have the right to our own security, safety and privacy. Unfortunately these days more and more, we have to take active steps in protecting these rights. Whether you are looking to protect your residence or business, electric fencing is a choice growing fast in popularity. Fencing technology has improved in leaps and bounds over the past few years, and Stinger electric fencing, available through Tandem Security, has stayed at the forefront of these developments. So why would you need electric fencing and what will it do for you?

The main purpose of electric fencing is to keep intruders out. It secures the residents inside the perimeter and protects your property and valuables. To ensure true peace of mind, however, you need to be sure that the fence is installed by professionals and that it is of good quality. The supporting structure needs to be strong enough and the voltage needs to be as high as possible within the legal requirements. The point is to give a powerful jolt to the intruder, causing them to react in pain and move away from the fence.

Another very important factor is that the energiser, which supplies power to the fence wires, has a siren that will go off when the wire is tampered with or cut. An electric fence is of no use if it cannot warn you of an intrusion. Many of these can even be linked to armed response, making it an all-round security feature that you can rely on with ease.

Safety requirements differ, depending on what type of property it is and what the dangers are being faced. In this way, government property, commercial and industrial zones and normal residences will have different needs and consideration to be taken into account.
