BNC Video Connections and OSD Controls

HD-SDI CCTV Box Camera

The above image shows the back of the HD-BX7 camera. This camera is dual voltage, so the power screw terminals can be connected to a 12V DC or 24V AC power supply. The RS-485 connections allow you to connect a cable pair to control the OSD (on screen display) from a DVR or keyboard controller. The other way to access and control the OSD is using the joystick (up / down/ left / right) controls. The red LED indicates if the camera is powered on. The BNC output labeled CVBS is an analog CCTV video output that can be used to connect this camera to a CCTV test monitor when installing and focusing the camera. Last, the gold plated BNC output is the HD-SDI video output that can be connected to an HD-SDI DVR capable of 720p or 1080p video resolution.

BlackMagic Design Compatible

BlackMagic Design SDI Converter Compatible with HD-SDI Camera

This camera is compatible with BlackMagic Design SDI converters. CCTV Camera Pros used a BlackMagic UltraStudio Mini Recorder to capture the above sample images. Please note: The above illustration uses a HD-D20W dome HD-SDI camera to illustrate how to connect an SDI camera to a BlackMagic studio device. It works the same way for the HD-BX7-28 box style camera on this page.

This is how it works.

  1. The SDI BNC video output of the camera is connected to a RG59 BNC jumper cable.
  2. The other end of the BNC cable connects to the BNC video input on the BlackMagic converter box.
  3. The BlackMagic supports a Thunderbolt 2 output. The Macbook in the above picture only has Thunderbolt 3 inputs, so a Thunderbolt 2 to 4 converter is used to connect the BlackMagic box to the Mac.


Connect HD-SDI Camera to HDMI Converter

Installers can use an SDI-CR1 SDI to HDMI converter to connect this SDI camera to a TV or monitor to display a realtime live video feed. Please note: The above illustration uses a HD-D20W dome SDI camera to illustrate how to connect an SDI camera to TV using a converter. It works the same way for the HD-BX7-28 box style camera on this page.

This is how it works.

  1. An RG59 BNC jumper cable connects the green BNC video output of the camera to the BNC SDI video input on the SDI-CR1 converter box.
  2. The HDMI output of the converter box can be connected to the HDMI input on a TV or computer monitor.
  3. Please note that the above picture does not show the camera or converter box connected to the 12V DC power supplies that are included.
