5.8GHz Wireless A/V Camera
Part Number CM205-5V
The CM205-5V is a 5.8GHz / 10mW micro-sized wireless camera.
Despite its low RF power, It is intended to be operated only by
licensed ham radio hobbyists.
Note: Using this RF device in the USA and other countries may
require an amateur/ham radio license. Furthermore, some
countries may forbid its use. It is YOUR responsibility to ensure
that its use meets the requirements imposed by your
government’s RF spectrum regulations. Do not purchase this
product if you are unsure of the government requirements or are
unable to comply with them.
DPCAV or its resellers will not be held responsible for ANY problems that may occur
due to the use of this RF device. Use at your own risk!

INSTRUCTIONS
1
POWER:
The CM205-5V requires 5VDC at 200mA. The 1.3mm x 3.5mm DC power input
connector is center positive.
Important: The applied voltage must be less than 5.5VDC.
Exceeding the recommended voltage, or reversing the polarity,
will damage the camera and void the warranty.
An optional cable is available from www.dpcav.com that allows the CM205 to plug
directly into a compatible 5V R/C model receiver. A voltage boost accessory is available
for use with a 1S (3.7V) R/C LiPO battery. Other power accessories are available too.
It is normal for the camera to be warm during operation. Because there’s special
electronic circuitry inside the DC power connector, it may also be warm during use.
However, an unusually hot temperature indicates that the input voltage has been
exceeded (immediately disconnect power and check the applied voltage).
2
ANTENNA:
The antenna is a simple wire lead (monopole configuration).
Gently bend it away from the camera; do not allow it to lay
against the camera body or cable. For best performance the wire
should be pointed downwards and away from the camera, as
shown in the photo on the right.
3
FREQUENCY SETTINGS:
The small switches on the top of the camera are used to change the transmit channel
(frequency). Although there are four switches, only the first three are used for channel
selection. We recommend using a sturdy wood or plastic toothpick to set the switch
positions. Please see the frequency chart below.

VIDEO MODE SELECTION (PAL/NTSC):
A switch is used to configure the composite video type. It can be set to the two world
standards, NTSC or PAL. Please see the figure below.
Video Mode (switch setting)
Note: Power should be turned off before changing the video setting. If the setting is
changed when power is still on then (1) turn off power, (2) wait three seconds, (3) then
apply power again. This is required because the video configuration will not change
while the camera is operating.
5
MOUNTING ORIENTATION:
The camera should be installed with the frequency switches on the top side. This will
ensure that the camera view is in the correct orientation. The lens opening is at the
front of the camera, side opposite the power cable. Avoid touching the lens area;
contamination on the lens will affect the image.
6
EMI/RFI INTERFERENCE:
The CM205 may cause EMI/RFI (interference) to a nearby GPS reciever, model R/C
receivers, or other electronic items. If this occurs then move it further away from the
affected items and any related wiring. We recommend a minimum of 3 inches (more
may be required).
If this devices causes interference to licensed radio communications then operation
must cease until the interference problem is corrected.
