Only ever used autowatch. Used microwave sensors instead of ultrasonic sensors. Helps with the false alarms. Changed the external siren to a different one so i could tell the difference. also made it a bit quiter so if i did have a false alarm i would just have a glance if nearby. Also got 2 house screamers hooked up in boot and in cabin. These things stopped ne body sitting in my car. Most ppl could only stand up to 20 seconds in the cabin. Only extra sensor i got was a tilt sensor. Shock sensor will still read a glass break. As for the keypad it is more jsut to stop some1 who has found your key. Or if it was stolen. Anti Hijack is a good feature. Has override switch which is different from the brant. U cna just press the button and its all good. Overall the autowatch is a good alarm. Has alot of nifty features. Just make sure you service your alarm every 6 months or it will end up useless. No1 ever services there alarm that i know of.
