Turn your legacy alarm system into a modern connected home

There’s nothing wrong with your existing alarm system. Instead of completely replacing it, use the sensors and siren with your moden IQ Panel.

Trigger home automation

Your wired sensors can be used for home automation. Automatically turn on the lights when a door opens. Or record a video clip. Adjust the thermostat when a door or window was left open.

Detect intrusions and fire with Surety

If you’re going to use a wireless security alarm, choose professional grade hardware with secure wireless communication so you can be confident it will do it’s job.

Why should I use encrypted wireless communication?

The majority of security systems are not as secure as they could be. With technology advancing rapidly, it’s becoming more and more likely that someone who wants to compromise your security system can do so without much effort or expense.

IQ encrypted sensors send signals in a coded form that can only be understood by the alarm system they are connected to. This ensures that only your system can access the content of the message, keeping your sensor activity data safe and practically eliminating your system’s exposure to spoofing and replay attacks.
