  1.  The transmission distance in obstructed areas cannot be determined generally and depends on the specific environment.
  2.  Walls, glass, etc. can cause the signal coverage to be shorter or disrupted.
  3. The max. transmission distance (80 m) is reliant on optimum conditions. Other devices in the vicinity using the 5 GHz band (WiFi networks or other wireless video transmitters) can lead to interference and a significant decrease in the transmission distance or picture stability.
  4. Make sure your input AC voltage is compliant with the adapter specifications.
  5. Only use the power adapters provided with the DS-55314 and DS-55315.
  6. If you use your own adapter, make sure the power output is 5V DC, 2A.


Problems Causes Solutions
1.No signal output after correct connection in the same room Maybe the sender
and receiver are not paired correctly To rebuild Sender and Receiver

connection: Please follow the setup procedure from “Installation for DS-55315 (receiver unit)”
2.No signal output after correct connection in different rooms| The distance can’t reach 80 m due to the signal loss via passing through the solid walls.| When passing through a solid wall (thickness under 30 cm), the signal will lose approx. 30 % of the original signal and the distance will be shorter than 50 m; if pass through two or more solid walls, the distance will be shorter than approx.
20 m. Please get a shorter distance at pass through solid wall application
3. The video transmission is not stable or the distance is shorter than described| Maybe there have some same band Interference sources at 5 GHz that affect the extender’s signal transmission.| Please place the product closer when there have same band Interference sources or remove the Interference sources
