B.Introduction
Thank you for purchasing this 2.4GHz Digital transmission system. This system is a
digital wireless receiver/digital wireless CMOS camera that uses 2.4GHz Frequency
Hopping technology and GMSK modulation, and each client has an ID for paring to
protect personal privacy.
Multiple receiver can get max. 4 pcs wireless cameras KW2431 to be quad display on
one TV monitor, or connect to DVR BNC input.Single receiver can get only one.
1 pcs wireless cameras KW2431, and display on one TV monitor, or connect to DVR
BNC input.
There are over billion hopping sequences to minimize interference and deliver
consistently an excellent video and audio quality up to 150 meters away
(open site and line of sight)
Using this 2.4GHz Digital Wireless system, you can enjoy greater convenience and
security in many ways:
Safety & Security Application:
Connect a digital wireless camera as a wireless security system
Monitor your sleeping baby, playing children, the elderly, or the disabled on TV by
single or multiple receivers See who is outside the door on TV through digital wireless
CMOS camera.Monitors and records the meeting from another room.

Operations
1.Multiple receiver:long press PAIR/CH button will get into paring mode as E; press
PAIR/CH button shortly to switch the display as CAM1 → CAM2 → CAM3 → CAM4 →
Quad mode → CAM1…… sequentially by each pressing.
2.Single receiver:long press PAIR button will get into paring mode as E; press
PAIR button shortly to switch OSD on/off.
3.Multiple receiver:long press MODE button to get into SCAN mode, it will display
CAM1 → CAM2 → CAM3 → CAM4 → CAM1…… automatically every 5 seconds,
and press PAIR/CH button to stop; press MODE button shortly to switch OSD on/off.
4. Multiple receiver:long press PAIR/CH and MODE buttons until show up“Erase All
Pairing Data” , it will clear the pairing content ,so that it would be quick when you repair
G.Use Notes
1.Be sure the digital wireless camera and the receiver were connected to the
equipment correctly (e.g. Connect the digital wireless camera, and the receiver to
the TV or DVR).
2.When DC plug is pulled out from digital wireless camera or receiver, it needs to wait
for a few seconds to insert it again.
3.Adjust antenna to decrease interference. (vertical or horizontal)
4.In most situations, one pair has a better distance up to 150 meter(open site and line
of sight). When two pairs or more are used at the same time, it can automatically jump
to different channels. But the distance between pairs, preferably greater than 2 meter far.
5.If there are some reasons cause the devise stop, you can try to pull out and insert the
power plug again and make the devise re-link.
6.It is suggested to have 10 pairs mostly operated in same location, but the pairing can

Problems Possible Solution
Monitor(RX) shows TX power off; TX/RX distance is too long, so that transmission
“No Signal” signal is weak, please check and make it right
Check all cable connections
Make sure power plugs are pushed all the way in
No picture Check if the POWER LED of the digital wireless camera and
receiver is lighting or not? Their LINK LED should be lit
If Their LINK LED should not be lit, you must re-pair their codes
following the E. instruction of the manual
Adjust receiver and digital wireless camera antenna orientation
Try to place digital wireless camera and receiver in a more close-in
Interference location
If using a microwave oven, turn it off.
Remove microwave oven or wireless router from the path between
digital wireless camera and receiver
