Hello everyone. I have an asianwolf alarm system that has a shock sensor installed and a tilt sensor. The shock sensor I have installed so it only gives pre warning chirps. I want to install a motion sensor (or whatever its called). I want my alarm to chirp when someone walks right by my car, or looks in my windows. If I have my windows down, as soon as someone puts their arm or head in, the alarm will sound OR if they smash in the window, the alarm will go off as soon as they climb in. I am looking for a sensor that will be the easiest to adjust. Any ideas?

As I understand it you want more than one sensor. a glass break sensor and a proximity sensor. You can piggy back as many sensors as you like. One of the four wires will be the input, as long as your sensor gives it the required polarity, the alarm will either chirp or go off.
I have only one experience with proximity sensors and I hated it. A guy from Miami was at class with us. If a bird, cat or rat came with in 6 feet of his car, it would chirp, needless to say in Florida and spring/summer, there were plenty of birds, rats and cats about.

One thing you have to keep in mind with proximity sensors.  The sensitivity will vary.  If you have your windows tinted then it will change between having the windows up or down.  You can piggy back the sensors so you get the warn away as well as the full alarm.

Well how exactly do proximity sensors work? As far as I know (and correct me if I am wrong) is that they send out a invisible band when alarm is armed. When something gets inside the range of the band, the alarm is sounded or chirped. But the you said that windows being tinted will change all that, and I agree. And I have also heard that there sensors dont penetrate metal. I have already walked right behind a car, and it would chirp (or is that because of the shock sensor?) Basically how I want it is that I want something that will chirp when someone walks by my car, and my alarm to sound if someone smashes in my window and leans into the car. The way my alarm is set up is that I have the shock sensor set to only give warn away chirps. I have had no luck adjusting the sensor from not falsing so I simply cut the full alarm wire. The only way my alarm will sound is if the domelight turns on which is caused when any door is opened. If my hood or trunk is opened, my alarm will also sound. I have not had any luck with glass break sensors. I just want a sensor that will sense when someone has gotten into the car via the window.

well you goal is exactly what a field disturbance sensor is all about.  It is designed for convertible cabs but I install them in standard cab vehicles all the time.  With the DEI module that I use, you can adjust the sensitivity of both fields.  Setting the sensitivity is a little tricky, especially if you have tinted windows.  If you do have tinted windows, then the type of film used will also have an effect.  You can adjust the sensitivity so that if someone walks close to the car then it will give you the warn away chirps.  However, the field eminates in all directions equally.  So if you set the warn-away field for the side of the cars, then you might not get the same effect from directly in front of rear of the vehicle.  Then if you adjust the sensor to pick up people from directly in front or behind the car, then your sides might be a little bit too sensitive and you'll get a warn away if you're parked in a parking lot and someone parks next to you.

I set the sensitivity so that if someone is peeking in the window it will give the warn away.  If the car has tinted windows I will set it with the windows up.  In this scenario, if you leave the windows down, then it will increase the range of the field.  Since most of my customers don't leave the windows down while the car is armed, this isn't an issue.

One thing that you should be looking at is the falsing of the shock sensor.  If you hard mounted the shock sensor, that will give you more problems adjusting the shock sensor properly.  Make sure that your shock sensor is zip-tied to a large harness in the vehicle.  I usually mount the shock sensor to a harness that is accessible with the dash completely assembled so that I can adjust it easily, and that makes sure that when I put the panels back on, it isn't pinned against another surface, further increasing it's sensitivity.  If your shock sensor is integrated to the brain, again, make sure you didn't hard mount the unit to any surface.

My shock sensor is zip tied to the bracket that holds the brake light switch. In order to slip the sensor off the bracket, I need to remove a screw and remove the cover for the brake switch. I think the reason my shock sensor is so hard to adjust is because it is a single adjustment that does the warn away and full alarm. So its either I have it adjusted to low to where i can hit the car as hard as I want, or its too high to where rain will cause it to sound the alarm. It was a pain so therefore I went and cut that wire. Anyways, so you think it would be best for me to get the DEI module which you use? I do have window tint so it would affect the exterior strength. I just want a sensor that will be easy for me to install, and adjust. I have had problems testing these things to where the LED's wont light till I actually hit the sensor itself.

If you sensor is being that difficult, I'd try a different location and possibly mounting solution. My zip tied sensor doesn't seem as sensitive as my glued on one was.
Where you mount the field disturbance sensor will also effect how it picks up. Sheet metal and metal flake tinted glass will certainly reduce the range of the signal. Also, if you mount it in the dash the field will radiated from that position, which means that there will be less field towards the back. If possible it should be centrally mounted, say in a center console or near the dome light.

Ok, so what sensor brand would be best, along with model number if possible? When I test my sensors prior to actually putting them in the car, I touch the positive and negative to the battery and then walk to the car to see when the LED's light up. That way I know they are working properly. Is there is better way to test them?
