19. Range
The transmission range of the radio signals between radio camera and the screen/DVR is up to 300 m under optimum
conditions.

screen/DVR and radio camera on a plain, even meadow without trees, houses, etc.) is never possible in
practice.
Usually, the screen/DVR is set up in the house and the radio camera is installed, e.g., at a carport or in a
stairwell.
 Duetothedifferentinuencesonradiotransmission,nospecicrangecanbeguaranteed,unfortunately.
Usually, however, operation in a family home is possible without any problems.
If the screen/DVR does not receive any signal from the radio camera, reduce the distance between the
screen/DVR and the radio camera or align the aerials differently.
It is best when the aerials are in parallel to each other. The range reduces too far if the aerial tips point at
each other.
The range may be considerably reduced by:
• Walls, reinforced concrete ceilings
• Coated/metallised insulated glass, aluminium windows, etc.
• Trees, shrubbery, earth, rocks
• Proximity to metal & conductive objects (e.g. heaters, steel doors)
• Proximity to the human body
• Broadband interferences, e.g. in residential areas (router, WLAN devices, mobile phones, radio headphones, etc.)
• Proximity to electrical motors, transformers, mains adapters, screens
• Proximity to mains sockets, mains cables
• Proximity to badly shielded or openly operated computers or other electrical devices
