Home Security Kit

Add-on Window / Door Sensor




SKU: AK41TK Category:
Window / Door Sensor

Take your security beyond video monitoring with a Window / Door Sensor Set
from Lorex. Small, but incredibly crucial, this sensor will notify you the
moment a window or door has been opened. Simply stick the sensors on any
door or window frame in your home. Then, the moment that their close
connection is broken you will be notified through the Lorex Home App.
Connect a total of 10 sensors to the Lorex Sensor Hub or up to 32 the Lorex
Home Center to ensure you always know of any suspicious openings of any
windows or door openings.

Video-Free Security
Sensors provide indoor security without using indoor video cameras.
Easy Setup
Connected using the Lorex Sensor Hub or the Lorex Home Center.
Real-Time Alerts
Receive mobile notifications the moment a sensor is activated.
Link Cameras
Automatically start the recording on a compatible Lorex security camera

Do I Need A Starter Kit to Use Add-On Sensors?


If using standalone or with an NVR or DVR system.
Add-on Sensors connect to The Lorex Sensor Hub, which connects to the Lorex Home App.


If using with the Lorex Home Center
Add-on Sensors are connected directly to the Lorex Home Center without a Lorex Sensor Hub.

Link Sensors To Lorex Security Cameras

Automatically start the recording on a compatible Lorex security camera the moment an add-on sensor is activated. This means that the linked camera will already be recording before it is able to detect the motion itself, which can give you valuable pre-event video to provide more context.

Sensor Linking with Wireless Cameras

The Lorex Sensor Hub is able to link connected Add-On Sensors to other Lorex wireless product connected to the Lorex Home App, such as Indoor and outdoor Wi-Fi Cameras*, Wi-Fi Video Doorbells, and Wi-Fi Video Floodlights.

Sensor Linking with Wired Cameras

The Lorex Sensor Hub is able to link Add-On Sensors to wired cameras through select recorders. Please see the compatibility chart to see which NVRs and DVRs can use this feature.

Arm/Disarm with ease

Manage your sensors with the Lorex Home™ app. Using this app, you can arm or disarm all, or specific, sensors from wherever you are.

Small But Essential

The Window/Door Add-On Sensor is very small (22mm × 36mm), allowing you to place many around your house unobtrusively (up to 10 on a Lorex Sensor Hub or up to 32 on the Lorex Home Center).

Compatible With Lorex Home Center

This device can be added to the Lorex Home Center along with other indoor and outdoor Wi-Fi cameras, video doorbells, floodlight cameras, and alarm sensors.
*The Lorex 2K QHD Video doorbell is not currently compatible with the Lorex Home Center.
