Getting Started

Install and wire the camera according to the instructions in this manual and in the manuals

5.1

Establishing Control of the Camera

The MIC612 supports two communication protocols (Biphase and RS-485), and both Bosch
and Pelco D and P (keyboard) controller protocols that allow you to send commands to the
camera and to receive information from the camera.
5.1.1

Establishing Control of the Camera via Biphase Protocol

NOTICE!
Biphase protocol works only with Bosch controller protocol. It does not work with Pelco
controller protocol.
Biphase is the standard Bosch protocol used to send Pan/Tilt/Zoom control data. Biphase
connections require a MIC-BP3 or a MIC-BP4 Biphase converter (sold separately).
