How to get the most from your wireless security cameras

Wireless security cameras are perfect for long distance and high-up security system installation. Here are some tips that will help increase signal strength so you can maximize the range of your wireless security cameras.

Optimizing your signal

The strength of the wireless signal between the camera and receiver will ultimately determine the quality of video you will receive. The stronger the signal strength, the higher the video frame rate (smoother video). The lower the signal strength, the lower the video frame rate.

Maximizing Signal Strength

Understanding the factors that can strengthen and degrade a wireless signal can extend your wireless camera range and maximize your video footage.

Line of site

Line of Site

Try to limit the amount of obstructions between the camera and the receiver. A clear line-of-sight will provide the strongest signal.

Positioning antennas

Positioning Antennas

High gain antennas point the wireless signal in a single direction to create a more focused, narrow signal that targets the receiver.

Competing signals

Competing Signals

Avoid placing cameras or receivers near other wireless signals and leave as much space as possible between wireless receivers.

How barriers affect wireless signals

The signal range varies depending on the type of building materials or objects the wireless signal must pass through as it travels from one point to another. Different kinds of materials (or weather) will cause different signal reactions:

Reflection

The signal reflects back off an object similar to a ray of light

Scattering

The signal scatters into multiple new signals

Attenuation

The reduction of signal strength during transmission. This loss is increased by long distances or as the signal passes through objects

Refraction

The signal changes direction as it travels through an object

Diffraction

The signal changes direction as it passes around an object

Material vs signal reduction

Cubicle walls, drywall, and windows generally do not seriously degrade wireless signal strength as these materials are typically thin and light. This allows the wireless signal to pass through with limited impediment. Other types of building materials can significantly degrade the signal, however:

Tips for extending wireless range

Wireless range extender antennas

Use the 2.4GHz Directional Wireless Panel Antenna to focus a wireless signal onto one specific camera or extend the range of more than one wireless camera with the Omni-Directional Antenna. These two types of extenders can also be combined by connecting the directional wireless panel antenna directly to the camera.

Extension cables for analog receivers

Mount the wireless receiver further away from the DVR using a Siamese BNC extension cord (60ft maximum). This will allow you to place the receiver in a better position to optimize the signal. For example, you will avoid a great amount of signal reduction if you extend the receiver to the same room as the camera.

Weatherproof receivers

Many Lorex by FLIR wireless cameras (LW3211, LWU Series) include weatherproof receivers. Installing the receiver outdoors with the help of a Siamese BNC extension cord will provide a better line-of-site and greatly enhance signal strength for your outdoor wireless camera.
