Frequently asked questions
Q. How do I get communication from coax?
  1. Camera must be connected to a Vmax A1 dvr or HD-TVI dvr to have coax communication
  2. Camera has 2 video cables make sure to use blue cable for TVI.AHD signal and coax communication
Q. How to turn on WDR?
A. At the VMAX A1 DVR
  1. Right click and select PTZ controller
  2. Press Menu to access the camera's OSD
  3. Go to Exposure, Brightness and select WDR.
  4. Go to Exit Jump
  5. Select Save & Exit
Q. My camera has a spotlight effect at night.
  1. Enter the Setup Menu
  2. Go to Day & Night
  3. Enable SMART IR and adjust the level
SMART IR adjusts the image for IR cameras to eliminate LED light reflection and white spots in the image. By breaking down the camera’s field of view into five zones, Smart IR allows for even distribution of the IR light. This prevents excessive illumination on images that are in the front of the scene and offers a clear image in B/W without any loss of detail.

Note:  This is best adjusted at night

Q. My Camera image is flashing/flickering
  1. View the image to see if the environment has variable lighting
  2. If so, enable WDR or DRC in the camera’s menu
  3. If not, make sure power is sufficient and power cycle the camera
  4. Check cable and connectors

Wide Dynamic Range (WDR)

Wide Dynamic Range technology mechanically allows capturing an entire scene in challenging lighting conditions. One shutter is set to a short exposure, capturing the bright areas in the FoV, while the other is set for a long exposure, capturing the dark areas in the FoV. The camera then interlaces the images and combines them, capturing both areas with no loss of detail. This allows for an image capture even when there are very bright and dark areas in the camera’s field of view or images are distorted by a strong backlight.

  1. Enter camera's setup menu
  2. Go to Exposure
  3. Go to Backlight and select WDR
  4. Enter WDR submenu to adjust the level
  5. Save & Exit

Dynamic Range Compressor (DRC)

DRC enables dark areas in images to become more visible without overexposing the bright areas to create one perfect image

  1. Enter camera's setup menu
  2. Go to Exposure
  3. Select DRC
  4. Enter DRC submenu to adjust the level
  5. Save & Exit

Q. My camera is blurry at night but clear in the day
  1. Check the lens cover for dirt, debris, scratches, smudges or residue
  2. Tilt camera away from or remove nearby reflective objects
  3. Make sure rubber gasket is present and correctly seated on lens
  4. Clean lens cover with water and dry microfiber cloth
Q. My camera is no longer producing video.
  1. Confirm the physical connection on the dvr
  2. Switch with a known working camera
  3. Check power to the camera
  4. Check camera compatibility
  5. Check user rights
Q. My camera is stuck in Black & Whtie.
  1. Make sure the camera is compatible with the dvr
  2. Make sure the camera is on the right signal
  3. Make sure the camera is getting sufficient light
  4. Make sure the light sensor is not obstructed.
  5. Move camera to a known working port. If problem follows the camera then the camera is the problem
  6. Enter the Camera's setup menu and make sure Day & Night is on Auto
  7. Factory default/Initialize the camera
  8. Bench test the camera with separate wiring and power
  9. Send in for repair if the problem persists.
Q. There are horizontal rolling bars on the monitor.

This is a video ground loop due to more than one ground between camera and monitor/head-end

Ground Loop problems can be resolved by making sure that only one end of any video cable is
connected to a local ground. Make sure the video cable shields do not come into direct contact with
each other to prevent unintentional local grounding.

  1. Tape all connectors in such situations to minimize this risk.
  2. Keep camera runs as short as possible with all video cables cut to fit. Excess cable left along any run can increase the risk of interference.
  3. At the monitor end make sure all the CCTV equipment is connected to same power point to provide a common local ground.
  4. Implement a ground loop isolator
