INTRODUCTION

VTC-C680 (VTC-C680DN for D&N) and VTC-C750 CCD Color Camera (VTC-C750DN for D&N) are high performance standard box type color cameras that adopt the most advanced 410,000 pixel 1/3" CCD. They are designed to have a conventional camera appearance to act as a crime deterrent as well as remain unobtrusive when installed. Its versatile design supports CS mount lens options allowing for various angles according to the targeted installation environment. Their innovative LPF (Low Pass Filter) and DSP technologies help represent natural colors. They are designed for indoor use or outdoor use when installed in a weatherproof enclosure such as the VITEK VT-EH10.

By utilizing a SONY CCD as well as a SONY HQ1 DSP, this camera provides exceptionally sharp image quality up to 550TV Lines (for VTC-C750 & VTC-C750DN). Through its backlight compensation function, it is able to give brighter and sharper images of an object or objects darkened by background lighting or sunlight. Their highly sensitive Super-HAD CCD also provides an auto white balance function, ensuring accurate representation of colors under any lighting environment.

Either 24VAC or 12VDC (Non-Polarity) may be used with the use of a power adapter.

FEATURES:

• 1/3" Sony DSP Super-HAD Interline Transfer CCD
- Resolution of 480 Horizontal Lines (VTC-C680 / C680DN) / 550 Horizontal Lines (VTC-C750 / C750DN)
- 10x Sensitivity enhancement with automatic optical filter (VTC-C680DN / C750DN)
- Switches to B/W, enabling IR sensitivity in night mode (VTC-C680DN / C750DN)
• Enhanced sharpness compensation
• Very low noise and superior picture quality
- Sensitivity of 0.02Lux (B&W) (VTC-C680DN / C750DN) & 0.2Lux (Color) (VTC-C680 / C750)
• Supports DC (and Video) auto iris lens
• Automatic and Manual Removable IR Cut Filter (VTC-C680DN / C750DN)
• Digital signal processing (DSP)
• Automatic Shutter Control (AES)
• Automatic White Balance (ATW)
• Dual Voltage: 12VDC/24VAC

Potentiometer for Iris level control:

Used to set the video level by adjusting the iris of the connected DC drive (or Video) auto iris lens. This excellent lens control characteristic makes it very precise, very stable, and very easy to adjust the video level.

EXTERNAL CONTROLS

SW 1. ALC / ESC (Default: ALC)

Used to select iris control mode. When set to ESC, camera operates in electronic shutter control (ESC) mode and can be installed with a manual or fixed iris lens. ESC mode is the most economic solution but may have some following disadvantages comparative to ALC mode with auto iris lens:

• More smear and less clear image when shooting the very bright object.
• Color rolling or video level hunting may occur under the fluorescent light when the camera operates in ESC and INT modes (NTSC version only).

When set to ALC, camera operates in auto iris lens control mode and should be installed with an auto iris lens. Auto iris lens is used for best quality video.

SW 2. BLC (Backlight compensation) ON/OFF (Default: OFF)

If the subject you wish to view is too dim because of a bright background, set the BLC switch to ON to compensate for the bright background. With BLC on, the background brightness may saturate in some cases. This function may not operate properly if the object is too small compared to the area of the background. This function can be used with the linear shutter (EE or ESC) and be OFF with auto iris lens (AI lens or ALC mode).

SW 3. Flickerless ON/OFF (Default: ON)

Flickerless mode is useful in areas where AC main is 50Hz and TV system is NTSC such like Japan or AC is 60Hz and TV system is PAL to reduce the flicker under the florescent light. Where FL is set to ON, the low light sensitivity is down about 30%.

SW 4. AGC Turbo ON/ OFF (Default: OFF)

AGC is Automatic Gain Control

SW 5. Sharpness ON/OFF (Default: ON)

SW 6. Day-Night (ICR) ON/OFF (Default: ON)

DAY-NIGHT ON/OFF SW enables or disables the day-night mode. If set to ON, day-night mode is enabled and camera determines to enter / exit NIGHT mode from / to DAY mode automatically according to the scene illumination. When the scene illumination is getting darker than a half video level, camera changes its mode to NIGHT and removes its optical filter to get a higher video level and switches to B/W mode.

In NIGHT mode, camera provides the real time B/W video and can accept the IR light. When the illumination is getting brighter, camera returns to DAY mode and returns its optical filter and switches to Color mode.

If set to OFF, camera operates just like a normal camera and does not perform NIGHT mode.

EXTERNAL CONTROLS

SW 7 IR mode ON/OFF ((Default: OFF)

Used to reduce a possibility from Day to Night or reverse under a certain scene illumination. This mode was derived from a IR Cut filter mechanism which is switched from day to night or night to day based on scene illumination. A typical IR cut filter type D/N camera could be switched from color to B/W or reverse under specific scene illumination values, but sometimes iterations occur when switching from/to (Night <--> Day) under specific external IR light source. VITEK IR mode can give a little margin of the IR iteration at specific condition by increasing the threshold value (Night to Day) adjustment.

When IR mode is enabled, it reduces iteration of the filter switch (repeated IN and-OUT) during varying lighting conditions. In IR mode, the Night to Day threshold will be around 6.0Lux and around 4.0Lux when off. The Lux is affected by scene illumination, but has a limit to reduce IR iteration under stronger external IR light.

SW 8. N/A (Reserved for future usage)

POWER SUPPLY CONNECTIONS

VTC-C680 / C750 Cameras are dual voltage and can work with either 12VDC or 24VAC power. A polarity-matched connection for 12VDC supply is NOT required. Primary and secondary grounds are completely isolated to reduce the possibility of ground-loop problems. An operating voltage range of 9.5V-30V for DC and 12-28.8V for AC provides extra installation flexibility.

Installation Notes:

Before applying voltage, first connect the power supply to the camera, then connect the power supply to an AC source. Connecting a live power supply directly to the camera could trigger an improper reset from power jitter and cause damage from surge voltage when there is no load.
