My County recently switched to the VIPER system making all other scanners obselete. Several people on Facebook recommend I get the HomePatrol 1, which I did. I've had it a week and only hear activity after 8pm. It's way too quite the rest of the time. Why? My other concern is the batteries. If I keep it plugged up while at home, will the batteries overcharge? I've been asked by a local organization to monitor our county''s activity and report it on Facebook for the general public. If I don't hear anything, I can't report it. Others with the organization says there's activity around the clock. What should I do?
