I am impressed that the "CopperWatcher" is straightforward to install and appears to cover all the bases regarding vandalism to AC condenser units. Should the electric service, or refrigerant system, or the sensing / control / reporting wires be attacked, then the security can be set to IMMEDIATELY trigger a loud (120 db) siren and call the police. This can be done on a security system whether that security system is armed at the time or not --- provides great security coverage without a more expensive fence (which can be breached) being in the way. THANK you, CopperWatcher!
