CYPER Posted June 30, 2019 Share Posted June 30, 2019 I live in a block of flats on the 4th floor and want to install a LED floodlight triggered by a narrow angle movement sensor. There is a parking lot in front of the block and the installation height is around 10m. Can you recommend a movement sensor to detect people walking downstairs but not across the entire parking lot. Also what floodlight wattage would be sufficient for 10m height? There are 100,200,400,500,800,1000W on Amazon. Thank you. Quote Link to comment Share on other sites More sharing options...
sixwheeledbeast Posted June 30, 2019 Share Posted June 30, 2019 I doubt you will find and all in one unit that would do something that. Before you even consider anything I would contact the landlord and explain that you feel the need for better lighting in the area. It's not your responsibility to be adjusting the electrics in a flat Quote Link to comment Share on other sites More sharing options...

If we vusually rotate the block of flats 90 degrees then its face will be the ground and so installation will be at ground level. And the parking lot will be like the opposite wall 10m away. If I adjust the mounting angle of the sensor would it work? Most cheap sensors have a max distance of 12m. Quote Link to comment Share on other sites More sharing options...
sixwheeledbeast Posted June 30, 2019 Share Posted June 30, 2019 I still think the comment stands UK or not. If I where the landlord I wouldn't want someone modifying the electrics, especially in a HMO It sounds like it needs a separate PIR unit wired to the light location, depending on the setup you may need a few PIR locations and a 2way or intermediate. Hard to recommend something without understanding the full picture and also would be designed for UK wiring regs which maybe irrelevant. Light output should also measured in Lux which will give you a better indication than Wattage Quote Link to comment Share on other sites More sharing options...

james.wilson Posted June 30, 2019 Share Posted June 30, 2019 You could use a 4010 redwall.
