- NOTE: If you run the power cable through the mounting surface, connect power before attaching the camera to the wall.
- NOTE: If you run the power cable along the mounting surface, the cable must go through the cable notch on the camera base. This will keep the camera base flush to the mounting surface
- NOTE: Power cables are only weatherproof when fully inserted at the connection point. Power cables may not be submerged in water.

- • Make sure that the camera is plugged into a power outlet and that the power adapter is plugged in properly.
- • Make sure receiver is plugged into a power outlet.
- • Move the camera closer to the receiver.
- • Make sure video output cables are connected to your DVR.
- • Move the camera closer to the receiver.
- • Try repositioning the camera, receiver, or both to improve the reception.
- • The picture may become choppy when experiencing a lower frame rate (e.g. 6 frames per second vs. a higher 20 frames per second).
- • Try moving the camera closer to the receiver.
- • Remove obstructions between the receiver and camera.
- • "Washout" or "white wash" can occur when a strong light source is pointed at the camera lens. The camera lens is not harmed during a white wash.
- • Do not point your camera towards a bright light source.
- • If using during the day, the camera may not be getting enough light. Reconsider the position of your camera.
- • If using during the day, the camera may be getting too much light. Reconsider the position of your camera.
- • Night vision activates when light levels drop. The area may have too much light.
- • Night vision reflects when pointing a camera at a window. Move the camera to a different location.

Appendix B: Frequently Asked Questions
8. Appendix B: Frequently Asked Questions
8.1 Wired vs. Wireless Cameras
A wired camera has a video cable that transmits the video signal from the camera to a
recording or viewing device.
A wireless camera does not use a video cable. Instead, it wirelessly transmits the video
signal to a wireless receiver that is connected to your DVR. Wireless cameras do not
require video cabling to be run between the camera and the DVR, which reduces
installation time and cost.
8.2 Does a wireless camera require power?
Yes. Wireless cameras require two power sources: one connected to the camera, and the
other to the receiver. The term "wireless" refers to the lack of a video cable between the
camera and the receiver.
8.3 How far can a wireless camera transmit a video signal?
In an open field (with line of sight), a typical wireless camera has a range between 250 - 500
feet. 'Line-of-sight' means that there are no obstructions between the camera and
receiver. Obstructions include walls, buildings, trees, and certain electronic devices.
Materials containing moisture (for example, leaves) may also act as an obstruction. Cubical
walls, drywall, glass, and windows generally do not degrade wireless signal strength.
In a closed environment—such as the interior of a house—the wireless camera range is
between 100 - 165 feet. The signal range varies depending on the type of building materials
or objects the wireless signal must pass through.
The signal range also depends on whether there are competing signals using the same
frequency as the camera. For example, signals from cordless phones or routers may affect
signal strength. Adaptive Frequency Hopping Spread Spectrum (FHSS) technology
featured in the latest Lorex models greatly reduces signal interference.
