It might be the best investment you ever make

Intrusion detection gets all the attention when it comes to security alarms but a flood can be more painful and expensive than a burglary. If you already have a security system then adding water detection is low cost and helps protect you from big, sometimes priceless, property loss.

Use it where water might leak

Put an IQ Flood where water might leak. In addition to the basement by the sump pump, it’s great for installing at the base of water heaters, washing machines, sinks, and more.

Detect intrusions with Surety

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

Why should I use encrypted sensors?

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.

Surety is your connection to the award winning ecosystem, allowing you to use hundreds of best-in-class security and home automation devices from a single app that runs on almost anything. All that and the industry’s best customer service are why Surety is your home’s best friend.
