Smart Security Sensor Installation in Leicester
We install multi-function PoE sensors that go beyond basic intrusion detection. Motion, temperature, humidity, water leaks, and ambient light - all monitored by a single hardwired device with no batteries, no wireless signal, and no cloud dependency. These are commercial-grade sensors installed on the same PoE network as your cameras and sirens, feeding real-time data into one management interface.

What you get
Sensor type and placement specification
We assess your property and recommend which sensor functions you need and where each device should be mounted for maximum coverage. Every position is chosen for a reason.
PoE-powered hardwired installation
Each sensor is wired back to your PoE switch over Cat5e or Cat6. One cable delivers power and data. No batteries, no wireless hub, no signal repeaters.
Threshold and alert configuration
Temperature limits, humidity ranges, water detection sensitivity, motion zones, and light thresholds configured to your property. Alerts fire only when something needs attention.
Integration with CCTV and sirens
Sensor events can trigger camera recordings, siren activation, or push notifications. Motion detected in a hallway at night can start recording and sound the alarm simultaneously.
How it works
Assess
We survey your property, identify areas that need monitoring - motion zones, rooms at risk of leaks, spaces where temperature matters - and specify the sensor count and positions.
Install
Sensors mounted on walls or ceilings, cabled back to the PoE switch, and powered up. Cable routes run through lofts, cavities, and conduit for a clean finish.
Configure
Detection zones drawn, thresholds set, alert rules configured, and integration with cameras and sirens tested. Full walkthrough so you understand every reading and alert.
All-in-one sensors: what they measure
The all-in-one sensors we install combine multiple detection functions in a single PoE-powered housing. A typical unit includes a passive infrared motion detector, a temperature sensor, a humidity sensor, and an ambient light sensor. One device, one cable, four data streams. This is not a consumer gadget that needs a Wi-Fi hub and a cloud subscription - it is a commercial-grade sensor that feeds data directly into your local system over a hardwired connection.
Motion detection uses passive infrared to identify body heat moving through the sensor field. Temperature and humidity readings track environmental conditions in real time, which matters for server rooms, wine stores, lofts with water tanks, and commercial spaces with insurance-mandated climate requirements. The ambient light sensor detects changes in lighting conditions that might indicate a door being opened, a light being switched on, or a window being covered - data points that add context to other sensor events.
Environmental monitoring: water leaks, temperature, and humidity
Water damage is one of the most expensive domestic insurance claims. A leak under a boiler, a burst pipe in the loft, or a failed washing machine hose can cause thousands of pounds of damage before anyone notices. The environmental sensors we install detect water at floor level and alert you within seconds. Place one under the boiler, one by the washing machine, and one in the loft near the tank header, and you have early warning that can save you a complete ceiling replacement.
Temperature and humidity monitoring serves different purposes depending on the property. In a home, it can alert you if the heating fails while you are on holiday - a frozen pipe is worse than a high gas bill. In a commercial setting, it can monitor server room temperatures, cold storage compliance, or warehouse conditions where humidity affects stock. We set alert thresholds during installation so you only hear from the sensor when a reading falls outside the range you have defined.
Motion detection vs PIR alarm sensors
The motion detection built into these sensors uses the same passive infrared technology as traditional alarm PIR sensors, but with better discrimination. The sensor can distinguish between a person walking through a room and a draught moving a curtain, because it analyses the size, speed, and heat signature of the moving object. This significantly reduces false triggers compared to older PIR sensors that fire on any change in infrared energy.
Motion events are logged with timestamps and can be linked to camera recordings. If motion is detected in your hallway at 3am, the system can simultaneously start recording on the hallway camera, activate a siren, and send you a push notification. During the day, the same motion event might just log quietly. The response is configurable per sensor, per time window, which means the system behaves differently when you are home versus away.
Pairing smart sensors with a PoE siren
Smart sensors detect events. A siren makes sure those events get a response. When a motion sensor detects movement in your hallway at night, or an environmental sensor detects water pooling under the boiler, pairing that detection with an audible alert ensures you wake up and deal with it. The siren sits on the same PoE network and activates within seconds of the sensor trigger - no cloud processing, no gateway delay.
The combination of detection and response is what turns individual sensors into a security system. If you are considering adding audible deterrence alongside your smart sensors, our PoE siren installation covers how the siren integrates with motion and environmental alerts for instant audible response.

Why Doberman
Multi-function in one device
Motion, temperature, humidity, water detection, and ambient light in a single PoE-powered sensor. One cable, one device, multiple data streams.
Commercial-grade hardware
These are not consumer smart home gadgets. They are commercial sensors designed for continuous operation on a hardwired PoE network - no Wi-Fi hub, no cloud subscription.
Configurable alert thresholds
Temperature limits, humidity ranges, and motion sensitivity set during installation. You get alerts when something needs attention - not constant status updates.
Local processing, no cloud
All sensor data is processed and stored on your local network. No third-party cloud service sees your data, and the system works without internet.

Frequently asked questions
- What does the all-in-one sensor actually detect?
- Motion via passive infrared, ambient temperature, relative humidity, ambient light level, and water presence at floor level. All five readings are reported over a single PoE connection and visible in the management interface.
- Do I need one sensor per room?
- It depends on what you are monitoring. For motion detection, one sensor per room or zone is typical. For water leak detection, you need a sensor at each risk point - under the boiler, by the washing machine, in the loft. We specify the count during the survey based on your actual requirements.
- Can the sensors trigger my cameras?
- Yes. A motion event or environmental alert can trigger the nearest camera to start recording, switch to a higher frame rate, or tag the event for easy playback. This gives you visual context for every sensor event.
- Are these the same as smart home sensors like Hive or Ring?
- No. Consumer smart home sensors are wireless, battery-powered, and depend on a cloud service to function. The sensors we install are hardwired via PoE, process data locally, and do not require internet connectivity or a subscription to operate.
- Can I set different alert rules for day and night?
- Yes. Alert rules can be time-based so the system behaves differently depending on the time of day or whether you are home or away. Motion in the hallway at 3am triggers a siren and notification; the same motion at 3pm just logs quietly.
- What happens if a sensor detects a water leak?
- The system logs the event, sends a push notification to your phone identifying which sensor triggered, and can activate a siren if configured. Early detection of a leak can save thousands in water damage repairs.
