Door Sensor
For front doors, service doors and side entrances where installers need clean opening detection without wiring through finished interiors.
- Battery-free opening trigger
- Wireless signal to alarm hub
- Ideal for villas, homes and apartments
Protect the real entry points
Most break-ins still begin with a door or window opening.
Perimeter detection is powerful, but everyday security still depends on knowing when a door, window, balcony door or sliding entry is opened. Apeiron Guard adds a maintenance-free opening detection layer to these final access points.
When the protected entry point opens, the sensor instantly sends a wireless signal to the alarm hub. The system can trigger a local siren to deter the intruder and send a real-time mobile notification.
We detect opening events the moment an entry point moves.
Movement-powered detection turns doors and windows into active security points without routine battery service.
One sensor principle · multiple entry points
Cover the doors and windows that matter most.
The Door & Window Sensor is built for the everyday access points installers protect again and again: main doors, windows, balcony doors and sliding entries.
Window Sensor
For windows and smaller frames where a compact wireless sensor can detect opening while preserving a clean residential appearance.
- Low-profile frame installation
- No sensor battery replacement
- Useful for retrofit security upgrades
Battery-free signal architecture
The opening action becomes the power source for the alert.
No routine battery replacement. No signal wiring across finished frames. The entry movement itself powers the wireless transmission.
01
Entry point opens
A protected door, window, balcony door or sliding entry begins to open.
02
Energy is harvested
The sensor converts the mechanical opening action into the electrical pulse needed for transmission.
03
Wireless signal is sent
The alarm hub receives the alert without frame wiring or a replaceable sensor battery.
04
Siren and app alert
The system can trigger immediate local deterrence and send a real-time notification to the mobile app.
For installers · faster project delivery
Install more opening detection with less labour, less wiring and fewer return visits.
Apeiron Guard helps security installers and smart home integrators protect doors and windows faster: mount the sensor pair, pair it wirelessly with the alarm hub, and move to the next entry point.
Save installation timeNo signal wiring through finished frames and no battery compartment planning.
Reduce site disruptionSurface-mount on doors and windows instead of opening walls or pulling cables.
Complete more projectsA faster retrofit workflow helps crews cover more homes, apartments and entry-point upgrades in less time.
Three practical advantages
Built for real homes, daily use and real security.
Apeiron Guard combines easy installation, reliable opening detection and real-time app visibility, so installers can protect entry points cleanly while users know the current door and window status.
Easy Installation
Installers can mount and pair the sensor cleanly on common doors, windows, balcony doors and sliding entries without wiring or disruptive renovation work.
Reliable Opening Detection
Mechanical activation is tied to real door and window movement, helping installers avoid the maintenance and uncertainty of battery-powered contact sensors.
Real-time Open / Closed Status
The sensor and app let users confirm in real time whether each protected door or window is currently open or closed.
From opening event to real-time response
An opened door or window becomes a wireless security event in seconds.
The Door & Window Sensor is designed as the entry-point layer of the Apeiron Guard ecosystem, connecting physical movement at the frame to alarm hub response and mobile app awareness.
01Door/ Window Safety
Protected entry point detects opening movement.
02Wireless Transmission
Mechanical opening movement generates the energy pulse for transmission.
03Alarm Hub + Alert
Wireless signal is received by the local security system.
04App Alert
Immediate deterrence and real-time notification support fast response.
Mini alarm hub + app
Know when a protected door or window opens, wherever you are.
The Mini Alarm Hub receives wireless events from Door & Window Sensors, sounds an immediate local alarm and sends the entry-point alert into the Apeiron Guard app workflow.

Why battery-free matters
Traditional door and window sensors create maintenance. Apeiron Guard removes the recurring weak point.
Typical battery contact sensor
- Battery replacement schedule
- Many small service points
- Risk of dead battery blind spots
- Harder to scale across every entry point
Apeiron Guard opening detection
- Battery-free wireless triggering
- Opening-powered signal event
- Cleaner installation with less wiring
- Designed for whole-home entry protection
FAQ
Clear answers for door and window sensor projects.
Use these answers to understand where the sensor fits, how the battery-free trigger works, and why opening detection helps protect the access points intruders commonly target.
What is a battery-free Door & Window Sensor?
It is an opening detection sensor installed on doors, windows or sliding entries to detect movement without routine sensor battery replacement.
How does the battery-free sensor work?
When the protected entry point opens, the sensor harvests enough energy from that mechanical action to transmit a wireless security signal to the alarm hub.
Where can the Door & Window Sensor be installed?
It can be used on main doors, windows, balcony doors, patio doors, sliding doors and other framed openings that need clean intrusion detection.
Does it require wiring or battery replacement?
The sensor is designed for wireless, battery-free operation, reducing frame wiring and routine battery replacement compared with traditional contact sensors.
What alert does the system send?
The sensor sends a wireless signal to the alarm hub. The system can activate a local siren and send a real-time door or window notification to the mobile app.
Is this the same as a camera or motion detector?
No. The Door & Window Sensor is not a camera and does not rely on video recognition. It is designed to detect physical opening movement at the protected entry point.
Why use battery-free door and window sensors?
Door and window sensors are often installed in large numbers. Battery-free operation removes a recurring maintenance point from every protected opening.
Can this page act as a landing page for door and window sensor searches?
Yes. The page is structured around search intent for door sensor, window sensor, battery-free door sensor, wireless contact sensor, smart home security and opening detection queries.
