I am feeling your pain! I was gutted when mine was broken into, i cant begin to think what it must be like for them to be taken!!
My house is covered both front and back by CCTV, however this is no deterrent anymore...
I am now after some internal IP cameras, just not sure what to get... would like something with PTZ Features...
On the tracker front guys, i use my Road Angel as one... They do one which is connected via a sim card which costs £10 a month...
I just leave the device switched on in my glove box locked up..
In my old car it used to stay in the boot, however when my last car was broken into the idiots stole it!! Thank fully the police managed to track it down based on my tracking reports!
Heavily into tracking anyway and tried a few other methods out in my old card... it is what i used to do at my old company.
The company i am with now used to do the same thing until they sold that part of the business off just after i joined them.
Researching into a better solution now anyway, as my main problem is 5min updates... or even 1min updates are just not quick enough in a real life environment.
The police really struggled with me 2min updates and suggested that for them under 30 seconds, or even less would be much better!
I did trial a system that i had setup using a java app on a mobile.. worked ok, but you were reliant on the mobile not crashing etc etc.
One site i have used is
www.locatea.net as you can join up cheap tracking units and use their interface to monitor it...
Cheers
