Each opening and closing action powers RF event transmission. No recurring sensor battery costs.
PATENTED KINETIC ENERGY-HARVESTING TECHNOLOGY
Battery-Free Wireless Door & Window Security Sensors
Kinetic Energy Harvesting · 100% Battery-Free · Zero Sensor Wiring. Engineered for commercial offices, retail facilities and residential properties to eliminate recurring sensor battery replacements.
Protect the real entry points
More protected openings. No recurring sensor battery replacements.
Commercial offices, retail chains and property managers may protect dozens or hundreds of doors. Battery-powered contacts create repeated replacement rounds and potential blind spots when batteries run out. Battery life varies by product and usage.
Apeiron Guard harvests mechanical energy on opening and closing to transmit a wireless event. Protect compatible doors and windows without sensor cabling through finished frames. Routine inspection, alignment checks and functional testing are still required.
One sensor principle · multiple entry points
Battery-free protection across commercial and residential openings.
Choose the Door Sensor or Window Sensor to suit the opening geometry, then plan receiver coverage and zone allocation for each project. Keep the same discreet retrofit approach from a single apartment to a multi-site rollout.
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

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
Commercial Offices & Co-Working Spaces
Protect meeting rooms, server rooms and office entrances without battery replacement rounds. Larger deployments require planned receiver coverage and multiple hubs where needed.
Retail Chains & Showrooms
Monitor compatible entrance doors, inventory backrooms and display openings after hours. Opening detection complements CCTV; a separate tamper function is not assumed.
Luxury Homes & Balcony Sliding Doors
Protect compatible timber doors, sliding entries and aluminium window frames without sensor wiring. Use the Door Sensor where sliding-window geometry is unsuitable for the Window Sensor.
ELV & BMS System Integration
Use the compatible Wireless I/O Module and project-designed dry-contact interfaces to link supported alarm, CCTV or building-management inputs. Confirm electrical compatibility and commissioning requirements.
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.
Entry point opens
A protected door, window, balcony door or sliding entry begins to open.
Energy is harvested
The sensor converts the mechanical opening action into the electrical pulse needed for transmission.
Wireless signal is sent
The alarm hub receives the alert without frame wiring or a replaceable sensor battery.
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
Retrofit more doors and windows without pulling sensor cables.
Use the approved adhesive mounting system on clean, dry and suitable surfaces. Plan alignment, receiver pairing and repeated testing before handover; avoid unapproved screw brackets or direct mounting of the Window Sensor on glass.
Three practical advantages
Built for commercial properties, homes and everyday use.
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.
Protected entry point detects opening movement.
Mechanical opening movement generates the energy pulse for transmission.
Wireless signal is received by the local security system.
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
Replace battery service rounds with battery-free opening detection.
Typical battery contact sensor
- Battery replacement intervals vary by model and use
- Repeated labour and consumable costs across many openings
- Depleted batteries can leave protection gaps
- Wired alternatives require their own cable-routing plan
Apeiron Guard opening detection
- Opening and closing power the RF event
- No sensor battery purchases or replacements
- Approved adhesive retrofit with no sensor signal cables
- Regular inspection and functional testing still apply
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 the system support commercial offices and retail chains?
Yes, with project-specific receiver coverage and zone planning. The Mini Alarm Hub supports up to 30 sensors; larger sites may need multiple hubs or a compatible Wireless I/O Module integration. Confirm the design and test every protected opening.
