The disconnects could very well be the times I've had to reboot the firewall since I'm reconfiguring it. Not sure about the static. This has happened in the past and cleared itself. I have adjusted squelch and that didn't help. I've moved the unit closer to the window with no help. I've removed and cleaned the antenna connection, no help. So.... don't know what it is. Since the first report, I've hoped I would run across a deputy to ask if there are any issues. My luck is that I haven't seen a single one.
There will be disconnects from system reboots from time to time since I do keep the system up to date. Same with the firewall. The PC providing the feed is on a DMZ behind the firewall keeping it from accessing the LAN.
There are devices you can put on/in the car that will monitor where the teenager goes. You can remove it when he comes home and download the information that will include his path and speed. Also, if you have a smartphone and he does, you can install Google Latitude that will allow you to check his location at any time.
