The popularity of Electric Fencing has led to an increase in thefts of expensive energizers. By the very nature that a battery driven electric fence energizer is left in remote rural areas invariably on the edge of fields means that they are easy targets and liable to be stolen by thieves. It is very hard to disguise their presence as the fence itself is highly visible and possibly several miles long so a thief has to simply follow the fence to find the energizer and purloin it leaving valuable property or removing the necessary protection leaving people and property at risk. SelData with our Partners in the UK, India, China, and United states Has developed a range of energizers with active electronics that are able to register that the energizer has been tampered with. As the energizer is moved or removed from the input power source the electronics register this change and stimulate a text message to be sent to a preset mobile number. This function will remove the fear that a fence will be compromised and ineffective for an unknown period whilst predators invade, or your valuable property stolen.
