Directed Electronics 506T I.T. Audio Sensor

I installed this sensor's mic on the middle upside of the rear glass of my Corolla with the supplied 2 sided tape. The receiver at the trunk so it could be visible when it's opened and therefore easier to calibrate. The microphone picks sounds of highwave frequencies and triggers (-) into the blue wire (you can try hitting a glass bottle with some metal). it's simple, all the work I've to do was running a blue cable from the dash to the trunk. I just installed at back because thieves tend to break the rear door little triangle glass, instead of the larger door glasses, this works for them in many cases without triggering the full alarm, because shock sensor don't always pick 'shocks' from the back of the car when pressed toward using force on the door. Don't spec to see a big glass to be broken!! that will make a lot of noise and vibration to the car, so alarm with be on!!! only desperate theft fall in this category. I recommend this item, it offers more security to your car and all your valued items inside.

This is a great little sensor. If you're going to bother installing an alarm you might as well add this audio glass break sensor for a few bucks more. It is super simple to install and also very easy to adjust. the sensitivity with just the twist of a knob/screw. It works perfect with DEI alarms like the Viper or Clifford line. I picked one up for my Viper and for a few dollars I have a bit more security. If someone breaks your window, pops the hood, and cuts your power or siren wire then you're out of luck. It's just too easy to do. Shock sensors may or may not pick up the window breaking depending on how its done so this is a little extra insurance. It can zip tie to about anything during installation as it is very small and light weight.

I bought this audio sensor as an added layer of protection for my car. I wasn't sure if it would really live up to its description but I was willing to give it a try. I am glad that I did as it really does add another layer of security. What's great is that you can adjust the sensitivity of the microphone to suit your needs. I live in a highly populated city, so it took some time to find the right balance. Now it works perfectly and it will even give warning chirps if I accidentally tap my keys against the window but not go off when someone drive by with their speakers at max volume. Strongly recommend, especially if you have items you want to protect from 'smash and grab' break-ins.

You can find the installation manual online. And for anyone curious because I had a very hard time finding this information, it draws 1ma of power, so in other words extremely low power draw. My main complaint is that it's not quite as sensitive as I'd thought it would be. I found myself with the highest setting tapping on my rear windshield with a key and still not setting it off. But a rasping the rear passengers with a set of keys definitely did set it off. Also I did try to place the microphone in as open of an area as I could. It's by the steering wheel facing forward. Definitely would be great for a small car but with a large SUV with lots of space in the back I'd say make sure you have this mounted high or center and don't expect it to easily pick up the rear window. Another tip is to make sure you give it a good 45seconds to arm before you go testing it. I thought it was broken for a minute because it wasn't going off but that's because I just armed the vehicle then immediately started tapping the windows. All in all a worthy investment for the price I'd say, now knowing that you have yet another way to set off my alarm.

Works great! have to fine tune it still, i live next to a fire station and a hospital within 2 blocks so the sirens set the alarm off, had it set to max settings and rain triggered it so it does leave you with peace of mind that your car is safe. plug in and play with Viper 5706V, comes with one harness that you can also connect your shock sensor to. Put it on my dash next to left A pillar. Mic needs to be out in the open to pic up sounds. the tap of a key can set it off, also if you arm the car while youre inside and make ANY noise it goes off. Found out the hard way.

My truck was boken into 3 times. The first time, I had no alarm, but the cops caught the guys! The second time I had the alarm on, but was set too low and they got into my bed-mounted tool box (put a pad lock on it after that). The third time I was in bed awake watching tv. As soon as they poped the glass ( I heard it) the alarm sounded and they took off. This sound sensor did its job! After this third break in I added the Radar motion detector and had the dash security light changed from red to the much brighter blue. If you are thinking about putting an alarm on your truck / car, I recommend getting the addon sensors! Like me, you may whish you did.

I installed this together with an Avital 3100L. The only feasible place to put the microphone was up high on the A pillar. I turned the sensitivity up to the maximum, and no matter how much I rattle my keys against the glass, literally inches away from the microphone, windows rolled up, I can't get this to go off. However, if I shout, it goes off. So, how is this supposed to detect glass breaking, exactly???

For DEI alarms, this sensor is plug-n-play. The sensor comes with 2 major components, the audio sensor microphone and the sensor electronics box. The sensor adjustment is done via rotary knob on the electronics box, and there is a red LED for feedback during adjustment. For DEI alarms, the sensor port accepts the harness that is provided in this kit, along with instructions. To test, I would recommend having all windows rolled-up and using a set of car keys to jingle against the exterior of the window. The microphone can be mounted in two different ways. You can drill a 1/2" hole and push the sensor microphone through. Or you can use the provided bracket with 3M 2-way tape. I chose this sensor over the 508D (Field Disturbance) because I am afraid of the large amounts of Hilo rain that we get here (that may cause false trips of the alarm). ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ October 8, 2015 Update I finally got around to installing this sensor (along with the 507M Tilt Sensor). I spliced the two sensor harnesses together, with diode isolation. Both of these sensors (506 and 507M) go into the Sensor 2 port. I tested each sensor individually, and they both work and trigger the Sensor 2 on my alarm. The only dilemma is not sure what to call Sensor 2 on my remote (if this zone is triggered, you can have the 2-way remote say Glass Breakage or Tilt). I drilled a 1/2" hole, which may be a tad bit too big for this sensor (I didn't like the cheesy microphone mount that comes with this). Maybe if you can find a 15/32" drill bit?

Very sensitive. Picks up well and works well. Will recommend to others customers

This sensor ties into your existing car's security sensor system. It is unlikely that you will know how to connect this unit to your existing car's system properly. You will need to have your local car garage or dealer do it if you want it done properly. Simple fact. It might well be a good device - I don't know yet because I need to do the above.

Very nice and great price

Medio bien porque no es muy sensible
