Introduction
Palun -is a PoE powered Video Balun which can transmit both power and digital IP video
signal over coaxial cable. With Palun, you can easily upgrade the surveillance system from
analog to IP, leveraging the existing coaxial infrastructure without re-cabling , . Moreover a
smart switch design enables to better accommodate camera of different class level Palun s s.

How to Use the Switch on Palun?
The switch on Palun (the blue one only) is designed for adjusting the power output from
the P oE switch in order to better accommodate cameras of different class levels.
If the IP camera’s PoE type is Class 1~4, please switch it to C1+.
(If your IP camera s class level is 1, Palun will advertise it as Class 2 to the PoE switch; if the
camera is Class 2, Palun will advertise it as Class 3 to the PoE switch, and so forth)

Why to Use the Switch on Palun?
Originally, if your camera is Class 1 and consumes 4W, the PoE switch detects the class
level and sends which is sufficient to power up Class 1 guaranteed maximum 4W of power
the camera. However, Palun also consumes w2 atts of power, so the total power
consumption (6W) of both Palun and IP camera exceed ed by s the power (4W) deliver the
PoE switch.

Now, if you switch Palun to C1+ (for Class 1~4 IP camera , only) it will help to increase the
guaranteed power output from the PoE a switch by dvertising a higher class level.
Therefore, in our example above, even though the IP camera lass 1, Palun will advertise is C
it as Class 2 to the PoE switch so that the PoE switch w ill reserve a Class 2 guaranteed
power (7W) for devices connected to this port. Then, it is now up both sufficient to power
camera and Palun.
