PMC Modules
User’s Manual
This case shows user installing a new surveillance IP camera using the existing coaxial cable
which is connected and used by an analog camera. Therefore, no fresh wiring is involved and
cost down is achieved
As user wants to add a new IP camera in addition to the existed analog camera, it is therefore
necessary to use a coaxial splitter device. Furthermore, user must add a modulator device
between analog cameras and coaxial splitter, and add a demodulator device between coaxial
splitter and surveillance center device. If user wants to add more new IP cameras, it only needs
to install a switch hub device between IP cameras and PMC100-2.
> Theory:
IP camera delivers image data through RJ-45 line. Analog camera delivers image data through
coaxial cable line. We use modulator/demodulator devices to separate a high frequency or low
frequency from the same frequency band.
