What brand of dual stage shock sensors are the most sensitive and adjustable? Do you use any single stage sensors? If so what brand? How many shock sensors do you need for an SUV or truck? Do you use a glass breakage sensor? If so what brand? Do you use microwave sensors? If so what brand is the most sensitive and adjustable. What brand of sensor do you just plain out despise? Don't be shy. This seems to be the most unresolved part of an alarm install on this site.

on viper alarms you can only use dei products so that takes care of that. on my wifes car i have a k-9 6 atv,by omega research. i have a microwave sensor by omega that is very sensitive, installed right in the middle of the car just under the parking lever, 1992 civic. under by the drivers kick panel i have a dual zone clifford shock sensor also sensitive, and another one under the trunk. also a glass breakage sensor by omega research that is sensitive enough to trigger the alarm when you tap the glass with an object.eg. key. try to avoid cheap sensors on ebay ive tried them just for kicks and they dont work as good. remember its how you mount them and where you mount them that makes them work their best so mess around with location until your content with the performance of a specific sensor.

Don't worry guys, I'm not letting this post die yet.. Just got in my DEI Shock and Glass sensors to install. Installed the shock in the same position as my Scytek shock to compare. Since it's late at night I only did a couple of knock tests with the alarm in test mode. Initial testing shows no difference in response. Price is comparable. Fit and finish on the DEI is very nice. Believe it is only the warn stage that is adjustable. Has one adjustment but is dual stage versus the Scytek dual adjustments. Will put the glass sensor in tommorow and do further testing. Fit and finish is very good on the DEI glass break sensor. Basicaly the Scytek Microwave sensor I have is useless to me as is. They offered to adjust it if I send them $5 shipping and handling. Probably will take them up on it. So far I'm thinking I'm going to need 4 shock sensors to properly protect my car the way I want it.

The glass sensor works fine. Rattling keys on the glass as advertised will set off the alarm. Had another problem with the system that requires the brain be returned. Will let you know how the microwave turns out. Will also do some more shock sensor comparisons. One thing I don't like about the DEI is that is only has one adjustment. Not sure if it's for the warn or alarm. I just max it anyways.

the adjustment is for the warn away. try placing the sensor in different locations until you are satisfied with its performace. i have mine straped to a thick wire bundle under the dash, but still out of the way to where you cant see it. even if i tap on the rear tires or bumper it triggers the warn away.

1. DEI are fully adjustable, as are most. dual zone would be shock/radar.
2. Single stage would be like a glass brake sensor, adjustable, tilt/motion sensor, adjustable, button type switches, magnetic switches, and mercury switches.
3. I would recommend 2 shocks for suv/truck. One under the dash and one in the rear.
4. I have DEI, but got it at cost, My most recommended sensor.
5. Microwave/radar is annoying, false too much, and I don't use them.
6. Cheapest type sensors. The other thing you need to worry about is integrating into other systems. Some manufacturers use a wire for warn and another for full, while dei uses multiplex timed triggers.

Thanks! The 504D DEI shock I have has a warn and a alarm wire coming out of it. Maybe it multiplexes for DEI alarms but also works with other alarms? Also it only has one adjustment on it. Believe it is the warn adjustment?

the way the 504d shock sensor works is that the green is the warn and the blue is the full trigger. the way it works with d.e.i. is 0.5 seconds of vibration from the 504d = pre-warn and 0.8 seconds of vibration from the 504d = full trigger. ( this is how they multiplex the circiut) the adjustment is for both when used with d.e.i. alarms. if you're using the 504d with an alarm other than d.e.i. product, then the adjustment is for one or the other, pre-warn(green) or full trigger(blue). ------------- do it right the first time....less warranty work=more money!:)
