The bottom line: it is best for offices, small rooms, and utility spaces where reliable line-voltage motion control and a wide 360 detection pattern matter most. The reviewer found the unit simple to install in standard ceiling grids or junction boxes, effective at picking up walking motion within its advertised range, and a practical choice when you want one self-contained relay to automate lighting without extra power packs.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e360 PIR coverage:\u003c\/strong\u003e The passive infrared sensor gives complete conical detection so a single unit can monitor a small room or private office without blind spots.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLarge motion optimization:\u003c\/strong\u003e Tuned for walking detection out to about a 24 ft radial range when mounted at 9 ft height, which suits corridors and open workspaces.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLine voltage relay:\u003c\/strong\u003e Self-contained relay operates lighting directly on line voltage so no external power pack is required for basic on\/off control.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEasy ceiling installation:\u003c\/strong\u003e Mounts to ceiling tiles, metallic grids, 3.5 in octagon boxes, or single gang boxes with included hardware for fast setup.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProgrammable time delay:\u003c\/strong\u003e Time-out is adjustable from 30 seconds to 20 minutes, allowing customization for occupancy patterns.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLong battery life and indicator:\u003c\/strong\u003e Push-button pairing with a green LED and long battery life under default settings reduces maintenance visits.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe CMR sensor is ideal for facility managers, electricians, and building owners who need reliable automated lighting in offices, small conference rooms, corridors, break rooms, and garages where line-voltage control is preferred.
