According to me One of the Best Solutions for in Home Theft of Car I came up, Might You Buddies like it:
1.Also INSTALL an ALARM Switch which turns on when the BONNET is Opened, Why? Mostly the First step of thief is to Cut off the Power wires of the Battery, to diffuse Alarm & the Movement Sensors(Like When some one Hits your Car Body Hardly,it turns on, Atleast in my car). Im pretty much sure that the alarm should turn on when the Back Window was Smashed or when the door is opened, why it didn't worked? Battery Power Diffused.
2.Try to purchase a different sounded Loud Horn, & attach it with Security System. Because whenever we hear the Typical Sounded Security Alarm we can thought its some one else's car not ours.
Otherwise it totally depends on your Luck! May ALLAH ALMIGHTY save us all!! AAMEEN
