DVR Video Signal

With the increased implementation of high definition (HD) video for analog cameras, the VMAX A1 recorder series features video signal options of HD-Analog (AHD), HD-TVI, HD-CVI, and CVBS (960H).

When connecting a camera to the VMAX A1, it is important to know what video signal that camera uses to stream its video.  If the DVR is not assigned to use the same video signal as the camera, it may result in video display issues such as:

  • Distorted images
  • Discolored images
  • Video Loss

This article will outline how to change the VMAX A1 DVR’s video signal by camera channel.

Note:  Make sure that the camera’s BNC connector is securely attached to the DVR.

Supported/Affected Devices

  • VMAX A1 Series (2.1 MP)
  • DW Starlight Camera Series (2.1 MP)

Changing Video Signals

To change the video signal of the DVR, you will need a display monitor and USB mouse directly connected to the VMAX A1 unit.  Without these peripheral devices, you will not be able to manage the system.

  1. Log in to the DVR as the admin.
  • Default ID:  admin
  • Default Password:  --- (blank)

Note:  If your DVR is no longer using the default login credentials and you have forgotten your password, you may submit a password recovery request for instructions to reset the password.

  1. Right-click with the mouse, then select Setup Menu.
  1. Select the Device menu, then click on Camera.

  1. The Camera menu will display.

Select the Channel that the camera is connected to.

Change the Video Type to match the same video output signal as the camera.

Note:  The DVR is set to automatically detect and use the video type of the camera, by default.  However, it may be necessary to change the Video Type manually, depending on the camera model.
