Wired door and window sensors use a magnetic contact system to detect when a door or window is opened. Typically, one part of the sensor is mounted on the frame and the other on the moving part. When the door or window is closed, the magnet keeps the circuit closed. If it's opened, the circuit breaks, triggering an alert in your security system. Wired sensors connect directly to your alarm panel, which can offer reliable performance since they aren't dependent on batteries or wireless signals.

Many wired door and window sensors are designed for DIY installation, but the process can involve running wires through walls or along baseboards.

• Check the installation instructions included with your sensor.
• Basic tools like a drill, screwdriver, and wire strippers may be needed.
• If you're not comfortable with electrical work or want a cleaner look, consider hiring a professional installer.

When picking a wired door or window sensor, consider these factors:

• Compatibility: Make sure the sensor works with your existing alarm system.
• Size and design: Choose a sensor that fits your door or window frame.
• Mounting style: Some sensors are surface-mounted, while others are concealed for a more discreet look.
• Durability: Look for sensors with sturdy construction for long-term use.

Keeping your wired sensors in good shape is simple:

• Periodically check that the sensors and magnets are securely attached and aligned.
• Gently clean the sensor surfaces with a dry cloth to remove dust or debris.
• Inspect the wiring for any signs of wear or damage.

Wired and wireless sensors each have their own advantages.

• Wired sensors are known for consistent performance since they aren't affected by battery life or wireless interference.
• Wireless sensors are easier to install and can be moved or expanded more easily.
