Ground Plane 

 If the camera and receiver are not mounted high enough above obstructions, the signal strength will be 
seriously reduced; therefore your distance will be reduced. The signal will literately bounce up and 
away from your intended target. This is known as a negative ground plane effect. The ground plane 
could not only be the ground you stand on, but could also be the rooftops of cars or distant buildings. 

See page 7.

 If we have a choice, place the camera/receiver, on the edge of the roof looking AWAY 

from the building, rather than installing them in the middle of the roof, shooting across the top of the 
roof. 

See page 8

This is particularly important if we have a metal roof that tends to deflect signals 

away from the target.

 

Also consider any obstruction that may get in the way, like another roof or a 

tractor-trailer that may pass through your “line of sight”.

 

Trees Grow!  

If we install the video link in the winter, the leaves that come out in spring may eliminate your wireless 
link. Are you trying to transmit through trees? Then you will need to seriously consider how much 
range will be lost. A field test is always the best way to find out. Speak to a VideoComm Technologies 
Tech for a possible solution. 
 

Unusual Traffic 

Watch out for unusual traffic in your transmission path. For example, a dump truck with the back 
elevated while dumping a load can be much taller than expected. Tractor-trailers or other large vehicles 
may be a factor if trying to transmit over a highway. Metal obstructions between the antennas cannot 
be ignored including electrical transmission lines that may not be obvious in the distance. Each high 
voltage wire crossing your path can be the equivalent of transmitting past an eight-foot thick steel pipe. 
Microwave towers may look fragile, but they can be as good as or equal to a solid steel door for 
blocking transmission.. The higher the transmitter and receiver are in the air, the higher the success 
rate. 
 

Things that block transmission 

Things that block transmission

 

are not always obvious. Here are some of the most common pitfalls: 

 

• 

Water, or anything with water in it (people are 98% water). Snow & rain can reduce your 

distance.  

• 

Steel, or anything with steel in it i.e. Steel-reinforced concrete (rebar) or metal window 

screens, or a tool-room cage. Aluminum siding, and energy-saving foil on the insulation in 
the walls are sneaky killers for radio waves. Some metallic paints or metallic wallpapers 
also block signals. 

• 

Mirrors block transmission, because the “mirror” consists of a metallic backing on the glass. 

• 

Lead windows will kill radio transmission; also windows that are UV coated may have thin 

metal energy-saving film.  

• 

High Voltage transmission lines (physically they look small, but for video transmission 

purposes, they might as well be 8-foot diameter metal sewer pipes. 

• 

Other materials like brick, drywall or wood, will also cut down on the signal, depending on 

water content.
