Where can I download the Lorex app?

Download the Lorex app from the App Store or Google Play Store.


Why is the camera not connecting to the Lorex app?

The 4K Dual-Lens Wi-Fi Security Camera can be onboarded on a 2.4GHz or 5GHz Wi-Fi network.

  • 5GHz networks will have limitations in Canada due to Industry Canada (IC) regulations; 3 of the 4 bands need to be disabled, as a result you may experience connectivity issues on the 5GHz frequency.

Where do I place the camera?

  • Place the camera in a wide, open space, and avoid placing it near any obstructions.
  • Place the camera at the central point of the area you wish to monitor.
  • Point the camera where there is the least amount of obstructions (i.e. tree branches).
  • Install the camera in a location that is difficult for thieves and vandals to reach.
  • Secure cabling so that it is not exposed or easily cut.

Other recommendations:

  • Place the camera close to your Wi-Fi router as possible.
  • Reduce the number of obstructive materials between the camera and the router or access point.

How should I position the camera?

When mounting the camera on a wall, make sure of the following:

  • Location: Place your camera in a wide, open space, and avoid placing it near any obstructions.
    • Height: Install your camera at a height of 10 feet (3 meters) above the ground.
  • Angle: Angle your camera to face outwards between 15-30°.
    • Distance: Position your camera 22-65 feet (7-20 meters) within points of interest.

Accuracy of motion detection will be influenced by multiple factors, such as the object’s distance from the camera, the height of the object, and the height and angle of the camera. Night vision will also impact the accuracy and distance of detection.
