Great explanation, thank you! That reminds me of how I tried to make colleagues understand why the alarm system didn't go off when a piece of ceiling cladding in a room at work came loose one night and fell down. "We have got motion sensors, it must set off an alarm", but they just didn't understand that something that has the same temperature as the rest of the room and therefore does not emit more infrared than everything else around it is invisible to PIR detectors. They just didn't understand it and thought our building's alarm system is just fake. Now I just need a video like yours in German, maybe they'd understand. However, when you mentioned the microwave detectors going through walls, I had to laugh, because that's what happened to me. I installed a hallway light with microwave motion sensor close to my flat's entrance door, and I noticed that the light already turns on when I walk up the stairs leading to my door. Fortunately this flat is the only on on the top floor of the house, therefore there isn't any foot traffic passing by making the light go on and off when there is no need for it. But on the positive side, if ans burglar things nobody is home because the lights are off, and sneaks up the stairs, they'll be greeted by a light that comes on when they are approaching, making them wonder if there is anyone in there. :-) So their capability of seeing through walls can be an advantage under certain circumstances.

I cringe when people wave their arms around in front of them to activate detectors that are far enough away, then they say "look it isn't very sensitive". Sigh! Yes, about the heat issue, that's why (unless they're really close) trees and bushes swaying doesn't activate external PIRs. I use Visonic Duo 360 PIRs (actually they are dualtecs) in our house - really small! The living room unit, the microwave part is always activating when someone is in the bedroom above - obvious that's fine. In PartSet, if the PIR doesn't detect anything then all is good! Thanks for the comment :)

Some PIRs motion detectors have an oddly shaped field of view though. The one controlling the light aboce the entrance to this building often times triggers when I am still parking my car quite a bit away from the door, but as I am standing in front of the door getting my keys out of the pocket it fails to detect me, no matter how much I move around. Having an alarm system inside someone's flat is really uncommon here, even for houseowners it's not that common to have an alarm system. Some do, but it's rare. Most alarm systems here are installed in business environments, where nobody is around at night - and also often nobody is in the neighborhood as well. Around poeple's homes here in Germany, motion sensors of all kind are usually a convenience thing to turn lights on when needed. Or like in my hallway the only way to turn a light on, the hallway of my flat seems to have been extended at some point, relocating the entrance to the bedroom - but the hallway extension didn't have any lights. Not wanting to make a big mess installing a light switch, I just routed a wire across the attic, coming down through the ceiling in the right place for a light - but the only option to turn it on was a motion sensor... Fortunately it doesn't detect motion close to the floor, as my cat (when I still had her) was able to walk underneath the light without triggering it. Greetings from Germany from somewone who has been following your videos for a really long time - probably not too long after you started this channel. :-)

Came across this informative video while trying to hack and adjust a wall-mounted solar-rechargeable driveway PIR sensor light I have. At first I thought the rechargeable battery was no good as the unit would stop lighting up early in the evening. Then I realised it was because the sensor was pointing not just at the driveway, but into the street where every car which passed would trigger it, hence running out of charge so quickly! Since this was a cheap model which did not allow for adjustment of the sensor direction, I experimented by placing a sticker over the top half of the hemispherical lens. That seemed to work well - it would not trigger if a car drove past, but it would if I walked onto my driveway. To try to make the hack more permanent, I coloured in half the sensor lens with several coats of a black marker. But that didn't seem to work and the sensor continued to trigger when a vehicle drove past, until I covered it again with a sticker. I'm wondering if it could be because the black marker ink doesn't block the heat radiation?
@mrmattandmrchay Жыл бұрын
Would be better to angle the PIR down to avoid it being aimed at the road. The upper zones of the lens are probably the most sensitive, as those are designed for 'distance'. The middle and lower set, the segments are smaller and are designed as look down zones. Ah - but I've just read that you cannot adjust the angle!! ...therefore the only way is to mask the lens. Colouring in the lens won't work, the ink thins out and doesn't apply evenly - if the PIR can see through the plastic lens, ink won't really do anything. Best way I found is silicon sealant to mask it. But PVC tape works just as well, cut it with scissors to make it look good (rather than tearing it).

Very interesting demonstration, I always wondered what the pulse count setting was for. I’ll have to try shining an led into some of mine and seeing that pulse pattern, would be interesting if manufacturers included an led in there for the purpose of aligning the sensor better. Perhaps in the addressable detectors even make it so you could enable said led from the panel itself. Great quality video as always, I really enjoyed it!
@mrmattandmrchay3 жыл бұрын
Glad you liked it! There were a couple of detectors which did have the 'lens zone finder' LED. One of which is featured in an up-and-coming video. Another of which was the Visionic SuperRed PIR, but essentially it was an LED that 'covered' the pyro electric detector, just so that you could see the zones. You had to remove the LED afterwards. But any LED that shows the zones would have to be placed in 'exactly' the same position as the pyro, therefore it couldn't remain there for normal functionality. Addressable PIRs (unless wireless which is totally different) are never a good idea, having data travelling up and down cables introduces a whole host of problems, with compatibility with panels, to data-issues on the cable. Thanks for the comment.

@mrmattandmrchay3 жыл бұрын
If you move slowly enough then it's possible, but I'd like to see a burglar break into a house and steal the widescreen TV moving that slowly! :D It also depends what part of the PIR lens is detecting you. If it's the main/upper set, then very difficult. The lower segments of the lense you'll notice on some PIRs are slightly larger, but less of them - it's to do with the angle of the lense compared to where the pyro is mounted on the PCB - the lens has to be enlargened to compensate.

It's a very simple way of joining two devices together so they can talk to each other using inputs and outputs. Only recently, a customer wanted a system to do something that wasn't achievable within the programming of the systems. But I added a few relays, a couple of timers, linked some outputs from system A, to inputs on system B, and managed to do exactly what the customer wanted. It was a little more complicated than that, but you get the idea? Never would have been able to achieve it without relays, even in 2021!! Good thing is, you can see exactly what's happening without software (i.e. is the relay on or off).
