Don't worry about leaving your pet in an office or vehicle when it's broiling or freezing outside. Heat Guardian provides absolute peace of mind.
A History of Success
Our first Heat Guardian shipped 7 years ago. Each revision of the circuit is more power efficient, longer range, and smaller. The firmware is based on open-source industry-standard operating systems and languages.
Our systems keep pets safe and secure - in the US, Canada, Britain and the EU.
