Motion Sensor Manufacturer — PIR Motion Detector OEM/ODM
深圳星廖智能科技有限公司
深圳星廖智能科技有限公司
A motion sensor, most commonly a PIR sensor, detects movement by sensing infrared changes across its field of view, and is used to trigger lighting, alarms or cameras. Xingliao, founded in 2014 in Shenzhen with 110 staff, manufactures PIR motion sensors in Zigbee, Wi-Fi and Matter versions for OEM security lines.
A motion sensor is the cheapest way to make a building feel intelligent, and the easiest way to make it feel broken. A sensor that triggers every time a cat walks past gets switched off within a week. A sensor that misses someone walking into a room at night gets uninstalled. Everything we do on this product is aimed at the narrow band between those two failures.
XingLiao manufactures PIR, microwave and dual-technology motion sensors in Shenzhen for brands, distributors and project contractors. We build on proven platforms with 7 to 15 day sampling, in Zigbee 3.0, Wi-Fi and Matter over Thread variants.
| Type | How it works | Best for | Weakness |
|---|---|---|---|
| PIR (passive infrared) | Detects a change in infrared energy across zones | Battery-powered sensors, lighting automation, most homes | Needs line of sight; misses slow or stationary presence |
| Microwave / 5.8 GHz Doppler | Bounces radio energy and detects movement in the return | Warehouses, corridors, places where mounting is awkward | Sees through thin walls and glass — triggers on the wrong side |
| Millimetre-wave (60 GHz) | Detects micro-movement including breathing | Presence detection for offices, care facilities | Higher cost, higher power draw |
| Dual technology (PIR + microwave) | Both must agree before reporting | Security applications where a false alarm has a cost | Requires mains or frequent battery changes |
The honest summary: buy PIR for battery-powered home products, buy millimetre-wave when you need true presence detection — someone sitting still at a desk — and buy dual technology only when a false alarm triggers a real-world response such as a siren or a call-out.
In markets with high pet ownership, a sensor that alarms at a 20 kg dog is a returned product. True pet immunity is achieved through lens design and detection-zone shaping, not through a "sensitivity" slider that simply makes the sensor deaf. We specify an immunity threshold in kilograms and test against it, rather than quoting a marketing phrase.
There is a trade-off worth understanding: aggressive pet immunity reduces effective range for a human walking normally. If your product is sold as security, that matters. If it is sold as lighting automation — turn the hallway light on when someone walks through — it does not, and pet immunity is clearly the better choice.
Battery-powered motion sensors are specified in triggers per day, not in months, because the duty cycle depends entirely on traffic. A hallway sensor in a family home may trigger 200 times a day; one in a holiday apartment may trigger twice a week. Publishing "two-year battery life" without stating the trigger assumption guarantees bad reviews from the first customer with a busy hallway.
We size the cell against a defined daily trigger count, we publish that assumption, and we include a low-battery report to the app so the customer replaces the cell before the device silently stops reporting. Silent battery death is the specific failure that makes customers distrust a whole system.
Standard housings with your logo, colour and packaging start at 500 pieces per colour. Firmware behaviour — trigger logic, reporting cadence, LED behaviour, app branding — starts around 3,000 to 5,000 pieces, and new enclosure tooling runs 25 to 40 days.
Sensors are almost always developed alongside door and window sensors, a hub, and either smart switches or curtain motors for the scene logic.
Motion sensors carrying radio modules need radio and EMC approval for the destination market: CE and RoHS for Europe, UKCA for Great Britain, FCC for the United States, PSE for Japan. Battery variants need UN38.3 transport documentation. Millimetre-wave variants face additional spectrum rules depending on the country — confirm the target market at enquiry, because a 60 GHz module approved in one region is not automatically legal in another.
PIR for battery-powered home products, microwave for awkward mounting or wide industrial coverage, dual technology when a false alarm has a real cost.
Yes, to a defined weight threshold. Ask for the tested figure rather than a marketing claim, and understand that higher immunity slightly reduces human detection range.
We quote against a defined daily trigger count. A busy hallway is not the same duty cycle as a holiday let, and any figure given without that assumption is not meaningful.
Yes. PIR detects infrared energy, not visible light. It works in complete darkness, which is why it is used for lighting automation at night.
Standard PIR cannot — it needs movement. For presence detection you need a millimetre-wave sensor.
500 pieces per colour on an existing platform. Custom firmware or tooling from about 3,000 to 5,000 pieces, 25 to 40 days for tooling.
Local scenes run on the hub, so a sensor can still switch a light during an internet outage. Remote notifications obviously need a connection.
Yes — light, camera recording, and notification can all run from one trigger, defined in the app's scene editor.
