The stronger the signal strength, the higher the video frame rate. The lower the signal
strength, the lower the video frame rate.
Full signal strength
(high frame rate)
Low signal strength
(low frame rate)
Q: Are digital wireless camera signals secure?
A: Yes. Lorex digital wireless products feature a wireless transmission method called Fre-
quency Hopping Spread Spectrum (FHSS). This type of signal is highly resistant to eaves-
dropping as it generates a channel hopping sequence using an algorithm generated by
the receiver, which only the camera can follow through the "pairing" function.
Pairing is an electronic handshake between digital wireless devices. Digital wireless cam-
eras can only be paired to one receiver. This is to prevent interception by third parties, and
prevents any other device from picking up the signal—this also means that you cannot pair
one camera to multiple receivers.
Q: How many frames per second should I expect from a digital wireless camera?
A: Current Lorex digital wireless cameras offer 10 - 30 FPS (Frames Per Second) perform-
ance. Actual frame rate depends mainly on signal strength (see the chart in section
above).
