Quick Sense(Qs-07):360 Degree PIR Motion Sensor Switch with Light Sensor, Energy Saving Motion Detector Switch, LUX Adjustment, Time adjustments 220V(2 PCS Pack)(Ceiling Mounted)

I bought 2 sensors. 1 has been working but has a poor sensitivity. It does not detects motion at times and even if it does its only from one direction. Other is not working at all. It detects motion as I can hear click sound but there is no output. Have submitted claim but no reply from seller. Went to office mentioned on their website and guess no signs of quick sense there. So, its a ghost company.Don't fall into trap. They claim that there is a warranty but when you claim even during warranty period they will charge 30% + shipping charges. So in reality there is no warranty. Its cheap Chinese product they are selling which even they don't trust.

Poor motion detection. Trouble started after 20 days. I bought 2 of such PIR sensors and feel cheated. You have to literally dance to detect motion. Better spend more and buy from reputed brand.Also it’s not 360 as claimed by the seller.” I would say you have to dance within 120 degree and within 1 mtr height to detect your motion. “ Seller may have to mention this in the product description

Good quality sensor with a good value for money. It worked well for me, I did multiple tests with detection range and the angle, it meets my expectations and need.Multiple benefits with single sensor.1. Energy saving - switches off the load (light) when not needed.2. Could be used for safety, some one enters the detection range, light is switched on.3. Could be helpful for elderly people during night time, they don't need to search for the switch, once they wake-up from bed light will be lit.Use case could be even more.I would recommend this product. Good value for money.. go for it.Thanks QuickSense for such a useful product.

I had asked this question (since we get the units in pairs) whether both can be installed in parallel to trigger the same lamp.. I did not get any response... HOWEVER, I have successfully installed these and both sensors work okay, both connected to the same lamp (at rear of my house) sensing approach from either side of the house.

I installed 5 of these PIR in our staircase which is usually dark with varying degrees of daylight at different times of day. So I had to set luminescent setting (sun and moon in the device) to work properly. Will it detect all motions during all the time? No, it works only if the settings in PIR match the device 100% of time, during other times it might be either slow to react or not work at all.So it works best for locations with same of of light all the time like dark room to control light.I find the sensor works well even in odd spaces like staircase and my settings are at darker side, so the sensor works well at night and not so well at daytime as some ambient light does fall in staircase depending on the floor.Also I found this roof mount works well only on the roof, if you mount on wall it's range is limited.I don't know how it works on high ceilings and how far it can detect, as my usecase is only for staircase.
