Problem Solution
No picture / signal • Ensure the camera is connected to a compatible DVR. For full camera compatibility, 
visit lorextechnology.com/compatibility.
• Ensure the wireless receiver is properly connected to the DVR.
• Ensure the power pack is properly inserted into the camera base.
• Connect the power adapter to your power pack to ensure the power pack is 
charged. The LED indicator on the power pack glows green for full charge, red for 
less than full charge.
• Remove obstructions between the receiver and camera. Materials such as brick, 
concrete and wood can significantly impact the wireless signal strength.
• Try repositioning the camera, receiver, or both to improve the reception. The 
receiver can be window or wall mounted using the included double-sided tape or 
mounting screws.
Battery life is too short • Ensure the camera is not pointing at a high-traffic area. Position the camera so it 
only captures areas of interest with no high-traffic areas (e.g., a busy sidewalk or 
roadway) visible in the image.
• Live video is being viewed too frequently. Viewing live video often will impact 
battery performance.
• Battery life will vary based on temperature, settings and number of events.
Picture is dropping • Move the camera closer to the receiver.
• Try repositioning the camera, receiver, or both to improve the reception.
Picture is or has 
become choppy
• The picture may become choppy when experiencing a lower frame rate (e.g., 6 
frames per second vs. a higher 15 frames per second). This may be related to signal 
strength or the camera’s resolution.
• Ensure the camera resolution is set to 720p using the Lorex Secure app or the 
DVR.
• Try moving the camera closer to the receiver.
• Remove obstructions between the receiver and camera.
Camera is not detecting 
motion
• Your camera may be too far away from the area of interest. Try to keep the camera 
within 20ft (6m) of the area you want to monitor.
• Review the “Installation Tips” section to ensure your camera is installed in an 
optimal location.
Picture is too bright • Ensure your camera isn’t pointed directly at a source of light (e.g., sun or spot 
light).
• Move your camera to a different location.
Night vision is not 
working
• The night vision activates when light levels drop. The area may have too much light.
Picture is not clear • Check the camera lens for dirt, dust, spiderwebs. Clean the lens with a soft, clean 
cloth.
Bright spot in video 
when viewing at night
• Night vision reflects when pointing a camera through a window. Move the camera 
to a different location.

To install your cameras:
1.  Set the mounting bracket in the desired mounting position. 
Mark holes through the mounting bracket (shown as orange 
X’s on the right). 
2.  Drill holes where marked for the mounting screws. 
 
3.  Insert the included mounting screws (×3) into 
the 3 holes closest to the top of the mounting 
bracket. Make sure all screws  
are fastened tightly. 
 
NOTES: 
• Insert the included drywall anchors if you are  
mounting the camera onto drywall.
• The hole at the bottom of the mounting bracket  
will be used in step 5, once the camera is attached  
to the mounting plate. 
4.  Lower the camera base onto the mounting 
bracket so the tab in the mounting bracket  
locks into the slot in the camera base. 
ATTENTION: 
This camera includes an Auto Mechanical IR Cut Filter. When the camera changes between Day/Night viewing 
modes, an audible clicking noise may be heard from the camera. This clicking is normal, and indicates that the 
camera filter is working.
STEP 4: Installing the Cameras
Follow the instructions below to secure the cameras. It is recommended that 
you refer to the “Installation Tips” section to help you select good mounting 
locations.

Installation Tips
• See images to the right for ideal setup. It is 
recommended to place your camera at least 6ft (2m) 
above the ground and angle it slightly downward toward 
the monitoring area, excluding any busy areas  
(e.g., sidewalks or roadways). 
• Ensure the camera image is free of obstructions (i.e., tree 
branches).
• Position the camera no more than 20ft (6m) away from 
the area you wish to monitor.
• For best performance, position the camera so that 
objects of interest will move from side-to-side across the 
camera image, rather than moving towards or away from 
the camera.
• Install the camera within range of the wireless receiver 
(noted in the camera’s specifications).
• This camera is weather resistant for outdoor use 
(IP65 rated). Installation in a sheltered location is 
recommended.
• Battery life will vary based on temperature, settings and 
number of events.
The wire-free cameras use a Passive InfraRed (PIR) sensor to ensure video is only 
recorded when motion is detected. Follow the tips below for more accurate motion 
detection and to optimize battery life:
Your cameras should be paired to the receiver and ready to use out of the package. 
If a camera becomes unpaired from the receiver, or if you have purchased a wire-
free add-on camera (max. 6 cameras per system), follow the steps below.
1.  From the live viewing screen, right-click to open 
the Quick Menu. Click Main Menu. If prompted, 
enter the username (default: admin) and your new, 
secure password.
To pair cameras with the receiver:
2.  Click one of the six blue buttons 
next to Pair to select the channel 
you want to pair the camera to.
3.  A timer appears on screen. Press the pair button (P) 
on the back of the camera within 30 seconds.  
7.  OPTIONAL: Lift up the rubber seal on the 
right-side release button. Tighten the locking 
screw using the included Allen key to secure 
the power pack in place.
8.  Twist the adjustment ring near the camera base 
toward the unlocked position ( ) to loosen and 
reposition the camera. Hold the camera in the 
desired angle while tightening the adjustment ring 
to secure the camera in place.
IMPORTANT: In order to pair cameras to the system, you must complete the full 
setup process outlined in “STEP 2: Setting Up the DVR”, including the steps in 
OPTIONAL: Full DVR Setup.
NOTE: A “pairing successful” message should 
appear on screen. If you do not see this message, 
repeat the steps above.
Charging the Power Pack
Use the included power adapter to charge the power 
pack. Connect the power adapter to the micro USB 
port on the power pack. The LED indicator on the
