 How do I choose an ALARM system
I have a 2004 E150 Cargo van. I unload the tools each night so they don't get stolen ( I had 2 ladders stolen while the Van was in my driveway). I am thinking about getting an alarm system. I have never had an alarm system before, so.
1. What should I look for in a system?
2. What should I look out for (avoid) in a system?
3. Any particular manufacturer and or system model reccomended?
4. For install Is it better to go through the dealer, my mechanic or someone that specializes in alarms? |
