Signal Reduction Through Materials
Signal strength decreases as it passes through different types of material. Try to position
your wireless camera and receiver in a location where the signal does not pass through
metal or concrete blocks, which can significantly reduce signal strength (as shown in the
table below).
Material
Plaster & Wood
Brick
Concrete Cinder Blocks
Metal & Metal Cladding
NOTE: Signals that must pass through wet or moist materials
(e.g. shrubs and trees) may be significantly reduced.
The stronger the signal strength, the higher the video frame rate. The lower the signal
strength, the lower the video frame rate.

9.4 Are digital wireless camera signals secure?
Yes. Lorex digital wireless products feature a wireless transmission method called FHSS—
Frequency Hopping Spread Spectrum.
This type of signal is highly resistant to eavesdropping as it generates a channel hopping
sequence using an algorithm generated by the receiver, which only the camera can follow
through the "pairing" function. FHSS makes digital wireless signals secure, private, and
interference free.
9.5 How many frames per second should I expect from a digital
wireless camera?
Current Lorex digital wireless cameras offer 10 - 30 FPS (Frames Per Second)
performance. Actual frame rate depends mainly on signal strength and resolution (see the
chart above).
For details on supported resolutions and frame rates for this model, see "Appendix A:
System Specifications" on page 8.
9.6 How many wireless cameras can I install?
It is recommended to install a maximum of 4 (four) wireless cameras per system. It is also
recommended to leave as much space as possible between receivers to minimize potential
signal strength degradation.
