Setup, DIP switch configuration, connections, and back-focus adjustment instructions for GE Interlogix (Kalatel) KTC-series black-and-white and color CCTV cameras.
This manual covers the GE Interlogix (Kalatel) KTC-510/515/540E black-and-white and KTC-810C/815C/840CE color analog CCTV cameras, covering lens setup, DIP switch configuration, connections, back-focus adjustment, and troubleshooting.
Warning: Do not expose the unit to moisture.
For auto iris lenses with a built-in EE amp: connect NC (no connection), Red (9VAC power), Black (ground), and White (video) per the lens instructions. For auto iris lenses without an EE amp, connect the Damping Coil (+/-) and Driving Coil (-/+) leads per the lens instructions.
| Switch | Options |
|---|---|
| ATW/AWB | Auto-tracking white balance / auto white balance (color cameras only) |
| BLC ON/OFF | Automatic backlight compensation on/off |
| NAGC/SAGC | Automatic gain control normal (30dB) or super (36dB) |
| r = .45 / r = 1 | Gamma correction (default .45) |
| L-LOCK/INT | Line-lock (external, default) or internal synchronization |
ATW mode (default): Color temperature is monitored continuously, and white balance adjusts automatically via an internal micro-controller across a 2500–9500K range.
AWB mode: The camera uses white as a reference to adjust red/blue content based on the scene. If color temperature changes continuously and the camera loses its reference, switch to ATW.
A digital light-level control system activated automatically via screen histogram (contrast) and 225-area window weighting integration, controlling iris gain and white balance simultaneously. Combines Central Window Weighted Average (best for a fixed main subject) and Histogram (best for a moving main subject) methods. Compensation may be insufficient when the background is extremely bright.
Electronically matches the brightness level seen by the camera to the level displayed on the monitor for correct contrast. Standard setting is .45 (default); use the manual switch only if monitor controls provide insufficient adjustment.
Line-Lock (external, default): Sync pulses reference the supply frequency; phase adjust buttons synchronize cameras on different power phases for roll-free pictures.
Internal: Uses an internal sync generator when the camera is powered from 12VDC.
Back focusing matches the lens' back focal length with the camera's imaging device, ensuring a sharp image across lighting conditions. Adjust in low light, with the iris fully open (minimum depth of field):
When the lens mode switch is set to DD, set the lens iris level adjustment to ensure correct exposure for the camera's position and lighting.
Accepts a local monitor's BNC connector, or a test monitor for checking camera setup.
Caution: This adjustment must be made by a qualified service person or installer. The vertical phase of the camera video signal can be synchronized to the AC power line phase using a dual-trace oscilloscope on the video output signal, adjusting the line-lock phase control buttons, or using a KTS-56 V-Phase Adjustment Tool. In line-lock mode, this is automatic.
| Problem | Probable Cause | Solution |
|---|---|---|
| No picture on monitor | Lens cap still in place | Remove the lens cap |
| No power to camera | Check power LED; check camera power supply if unlit | |
| Monitor not functioning | Connect a test monitor to MON OUT to check for local video | |
| Camera not set up for lens type | Set lens mode switch (VD/DD/AES); ensure auto iris plug is connected properly | |
| Picture quality poor | Dirty lens | Clean the camera lens |
| Monitor setup / termination incorrect | Verify monitor settings, termination, and cable integrity | |
| DIP switch not set properly | Verify DIP switch settings (see DIP Switch section) | |
| Camera not focused | Adjust back focus thumbwheel and lens focus ring | |
| Lens type mismatch | Attach/remove C-mount adapter as appropriate; check DD level |
