The HD321M4TIR is a 2.1 megapixel indoor dome camera with HD-SDI 1080P output. SDI technology serializes the video signal and transmits it uncompressed, eliminating distance and deformation issues that may affect the cameras’s image quality, making the image quality a true High Definition. The camera outputs the clearest high definition images with fatures like 3D Digital Noise Reduction and Wide Dynamic Range. DW’s HD-SDI cameras allow you to enhance your security system to full HD 1080P resolution while still using existing coax installation. DW’s HD-SDI line offers a reliable high quality yet affordable camera in just a few minutes.

TDN [True Day/Night] with IR Cut Filter
During daylight, the IR cut filter allows visible light to pass through, reflecting the unwanted infrared light. In low light environments, where artificial or external light is not available, the cut filter is removed from in front of the lens, allowing the camera to capture the infrared light that given out from the infrared LEDs, to capture as much light as possible to produce brighter images.

  • 3D DNR (Digital Noise Reduction): Automatic Digital Noise Reduction
  • D/N - Day/ Night: True Day & Night with IR Cut Filter
  • IR Distance: 50ft Range IR with Intelligent Camera Sync
  • Image Sensor: 1/2.8" CMOS Sensor
  • WDR- Wide Dynamic Range

Frequently asked questions
Q. How do I default the camera if I have a problem with image or signal?
A.
  1. Access camera menu from the dvr setup menu> enter preset 95> click set button>click device>click UTC/PTZ Tab.
  2. Go to Setup and select Initialize
  3. Press and hold the select button for five (5) seconds
Q. How do I get communication from coax?
A.
  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. My camera has a spotlight effect at night.
A.
  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 is blurry at night but clear in the day
A.
  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.
A.
  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

Q. My camera is stuck in Black & Whtie.
A.
  1. Make sure the camera is compatible with the dvr

Q. There are horizontal rolling bars on the monitor.
A.

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
