Why should I use encrypted sensors? Encrypted sensors send status details to their system in a coded form, readable only by the alarm panel they are paired to. This ensures that only the alarm panel can access the content of the message, keeping your sensor activity data safe and significantly reducing the system’s exposure to spoofing attacks.

The IQ Flood-S detects the presence of water and allows you to know when potential flooding occurs before extensive damage is done. Great for installing at the base of water heaters, washing machines, sinks, and more. Includes a 6’ wire with water contact sensor and encryption technology.
