Wirefree Intruder Alarms

Wirefree Intruder Alarms

Our current preferred wirefree system is from the Orisec range. We can install audible systems (bells only), self monitored or professionally monitored systems with connection to a central station with or without police response, and systems connected via your home internet which can be controlled by a smartphone with alerts in the event of an activation.These systems can be connected to external detectors and cameras to provide alerts and video verification, click here for details.

Every installation is different, so we do free site surveys for any new customer or site. We will discuss with you what our systems can do and design a system that can do exactly what you need.

We are accredited to the SSAIB and every new installation is carried out to the highest standards and an installation certificate is issued. (Any system which requires police response has to be maintaned by an SSAIB or NSI accredited installer. Insurance companies will often insist alarms are annually maintained by an accredited installer if they are declared on your policy).

The standard wirefree installation kit comes with the Enforcer control panel, external sounder, 2 movement detectors, 1 door contact and 2 setting fobs. Additional items can be added, including external detectors and cameras, all of which can send notifications to phones as well as the ability to remotely set and unset the alarm.
