The CATrak (models I and II) from CATrak Technologies is a catalytic converter theft deterrent that provides two lines of defense, one physical, and one digital. The product includes one CATrak module, one cut detecting device (CDT), and one siren. The CATrak module and siren can be installed inside the engine on the catalytic converter with a clamping strip, then, if the CATrak harness is cut or experiences vibration, the siren activates and the owner receives a notification via the CATrak app. As well as this, the CATrak module uses GPS to track the position of the catalytic converter once it is taken with an internal battery with a lifespan of 3 hours.
