Product details
Wireless window and door sensors with antenna are components of security systems that detect the opening or closing of windows and doors and communicate wirelessly with a control panel or hub. The addition of an antenna improves their wireless communication range and reliability.
How They Work:
1. Sensor Pair: Typically includes two parts:
A magnetic sensor (attached to the frame)
A magnet (attached to the window/door itself)
2. Magnetic Trigger: When the window or door opens, the magnet moves away from the sensor, breaking the magnetic field and triggering an alert.
3. Wireless Signal: The sensor sends a signal to the control panel using RF (radio frequency). This can be 433 MHz, 868 MHz, Zigbee, Z-Wave, Wi-Fi, or other protocols.
4. Antenna: Enhances signal strength and range. Some sensors have:
Built-in antennas (internal, not visible)
External antennas (visible, sometimes adjustable) for longer-range or more robust signal
Common Features:
Battery-powered (no wiring needed)
Tamper protection
LED indicators
Low-battery alerts
Long-range transmission
