STAR-LIGHT™ 2.1MP HD Over Coax™ 20X PTZ Dome Camera

PTZ and OSD Control via Coax (UTC)

UTC (Up The Coax) allows a user to access the camera's OSD (On Screen Display) through a coaxial connection, eliminating the need for an additional RS485 cable to reach the menu.

Tampering-Resistant Pan, Tilt, Zoom Domes

Digital Watchdhog® PTZ cameras use up to 30x optical zoom lens, which uses the internal glass elements of the lens to bring an image in closer and records over the entire digital sensor of the camera at full resolution. Combined with additional 16x digital zoom, the camera offers clear zoom up to 480x times.

Q. How to turn on WDR?

A. At the VMAX A1 DVR

Right click and select PTZ controller
Press Menu to access the camera's OSD
Go to Exposure, Brightness and select WDR.
Go to Exit Jump
Select Save & Exit

Q. My Camera image is flashing/flickering

View the image to see if the environment has variable lighting
If so, enable WDR or DRC in the camera’s menu
If not, make sure power is sufficient and power cycle the camera
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.

Enter camera's setup menu
Go to Exposure
Go to Backlight and select WDR
Enter WDR submenu to adjust the level
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

Enter camera's setup menu
Go to Exposure
Select DRC
Enter DRC submenu to adjust the level
Save & Exit

Q. My camera is blurry at night but clear in the day

Check the lens cover for dirt, debris, scratches, smudges or residue
Tilt camera away from or remove nearby reflective objects
Make sure rubber gasket is present and correctly seated on lens
Clean lens cover with water and dry microfiber cloth

Q. My camera is no longer producing video.

Confirm the physical connection on the dvr
Switch with a known working camera
Check power to the camera
Check camera compatibility
Check user rights

Q. My camera is stuck in Black & Whtie.

Make sure the camera is compatible with the dvr
Make sure the camera is on the right signal
Make sure the camera is getting sufficient light
Make sure the light sensor is not obstructed.
Move camera to a known working port. If problem follows the camera then the camera is the problem
Enter the Camera's setup menu and make sure Day & Night is on Auto
Factory default/Initialize the camera
Bench test the camera with separate wiring and power
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.

Tape all connectors in such situations to minimize this risk.
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.
At the monitor end make sure all the CCTV equipment is connected to same power point to provide a common local ground.
Implement a ground loop isolator
