Entrance Panel Cameras
When using a Modular system, The Modular Camera (KMBC3*) is automatically identified by
being connected directly to the TSMB3 and takes the same Entrance number (1-8) of the
TSMB3.
When using a Custom Panel with a TT33 Speaker/Microphone/Controller, You can use
either a pinhole or CCTV type analog camera with it's own power supply for system video
input. This camera will connect by coax to the KMB3-AM which is automatically identified by
being connected directly to the TSMB3 and takes the same Entrance number (1-8) of the
TSMB3.
Using analog cameras as add on observation cameras to the system.
You can add CCTV type cameras to the system that are not related to an entrance
panel to allow for observation of other areas using the KBS3-2.
As an example you could have 2 entries to the building using Camera #1 & #2, and use 3
observation cameras set as camera #3, #4, & #5. When a visitor rings from Entrance #1,
camera #1 will come on the monitor to display the visitor, but the resident can also cycle
through all five cameras by pressing the
When using any other camera(s) the KBS3-2 module must be used. This module has two
functions:
1. Converts the analog camera video signal to a digital signal that is used by the
QwikBus™ system. The analog signal is fed into this module from any pinhole or
CCTV type camera by a standard RG59 or RG6 coax and sends the converted to
digital signal out through the BUS connections to the system.
2. Establishes a Camera number for identification. If this camera is addressed as # 2 for
example, This KBS3-2 would be set to #2 using the dipswitches 4,5,&6 (7 is not used).
The 8 combinations are shown below.
NOTE: When using a Coaxial cable into a KBS3-2, ALWAYS connect a 75Ω ( for RG-59) or
50 Ω (for RG-6) End-of-Line resistor between the coax center lead terminal and the (
terminal on the KBS3-2. Failure to do this may cause degradation of the video signal.
