12V Wired PIR Motion Detector Alarm Infrared Sensor 360 Degree Detection Ceilling Mounted Installation Relay NO.NC Optional

[Music] hi in this video i'm going to demonstrate how to set up a motion detecting passive infrared sensor this is what it looks like i've got three different sensors all doing the same thing and i'm going to install one of these so that when you walk in the room it will activate the light to turn on and you can set how long it stays on for and then it can automatically turn the lights off i'll just show you these three prrs i'll then show you the principle of how you connect it and then i'll do the installation right the first thing you may notice is these have different wattages as you can see this one says 500 watts it's a small one this says 1.2 kilowatts or 1200 watts and this is 1200 watts you can also see that the size of them is also different so i'll show you them quickly right so over here is a small one and as you can see you'll have to drill into your ceiling here is the saw
