Zoom Chassis Camera, NTSC: EOL 2014

Discontinued 2014

The Hitachi VK S274R are compact chassis-type cameras designed for surveillance under very low light conditions. Thanks to the optimized On-Chip Micro Lenses, sensitivity is dramatically improved and the smear level greatly reduced, meaning objects are captured effectively even under poor lighting. The Privacy Zone Masking and Mirror Image functions improve the versatility of the Hitachi video cameras. These models are RoHS-compliant to enhance environmental friendliness. From crime prevention to surveillance, the range for CCTV applications is constantly expanding. This means the demand for high-sensitivity video cameras is now greater than ever. Hitachi's VKS274R series of high sensitivity color and monochrome video cameras, VK-S274R are developed to satisfy this need. They feature a newly-developed 1/4-inch, 410/470k-pixel CCD. Thanks to its dramatically improved performance, the new VK S274R camera achieves a sensitivity twice that of conventional cameras. Moreover, the smear level is greatly reduced compared with typical cameras. Images are practically blur-free.

The VKS274R newly-developed sensor features significantly improved performance to achieve exceptionally high sensitivity. On-chip lens technology mounts a micro lens on each pixel with ultra precision, so that concentrated light falls on sensors, thereby increasing video camera sensitivity. Superior high-sensitivity is the most outstanding property of the new Hitachi video cameras. For instance, the minimum illumination of the VK-S274R is merely 0.06 lx (color, 1/4s), meaning the camera is more than twice as sensitive as conventional cameras. Thanks to the improved structure of unit cells, the degree of light leakage is also drastically reduced to cut smear. These superior properties make the new Hitachi camera an excellent choice for applications in low-light environments. When there are windows, entrances and other objects within the camera's vision that are not subject to surveillance, they can be masked on the monitor for protection of privacy. This makes the VKS274R series of video cameras particularly suitable for outdoor surveillance. With these new RoHS-compliant models, make your organization environmentally conscious.

The VK S274R cameras enable you to not only monitor your environment but also help preserve it. You can control a six-division image area for backlight compensation. Remote operations are possible via the RS-232C, which allows control of the camera's focus, iris, zoom, shutter speed, etc. The mirror image function enables the reversing of the field of view depending on the camera's position. The Digital Slow Shutter allows the camera a long exposure time of 1/2 second. This translates into a higher sensitivity and minimum illumination of only 0.03 lx (color, 1/2s). Since more color data is captured and stored by the camera, you can see things not visible with conventional color video cameras. The VK-S274R built-in 22x optical zoom lens is highly reliable. It features auto focus, auto iris and zoom functions. In conjunction with 12x digital zoom, the total zoom ratio is 264x. A.I. Auto Iris: Adjusts iris so that video output is kept at a fixed level, even if surrounding illumination changes. A.I. Auto White Balance: Provides natural color reproduction according to ambient lighting.

APPLICATION USE
Surveillance: In corporate, medical, learning institutes and other public places, security camera solutions offer a peace of mind.
Traffic Management: Monitoring and responding to ongoing road activity in residential and business areas.
In Car Video: Hybrid use of a camera used in a vehicle.

Sensitivity to Visible Light is More than Doubled (Diagram)
Superior high-sensitivity is the most outstanding property of the new Hitachi video cameras. For instance, the minimum illumination of the VK S274R is merely 0.06 lx (color, 1/4s), meaning the camera is more than twice as sensitive as conventional cameras.

Privacy Zone Masking Function (Diagram)
When there are windows, entrances and other objects within the camera's vision that are not subject to surveillance, they can be masked on the monitor for protection of privacy. This makes the VKS274R series of video cameras particularly suitable for outdoor surveillance.

Environmentally Friendly
With these new RoHS-compliant models, make your organization environmentally conscious. The VK-S274R camera enables you to not only monitor your environment but also help preserve it.

Backlight Compensation
You can control a six-division image area for backlight compensation.

Remote Control through RS-232C
Remote operations are possible via the RS-232C, which allows control of the camera's focus, iris, zoom, shutter speed, etc.

Mirror Image Function (Diagram)
The mirror image function enables the reversing of the field of view depending on the camera's position.

Digital Slow Shutter (D.S.S.)
The Digital Slow Shutter allows the camera a long exposure time of 1/2 second*. This translates into a higher sensitivity and minimum illumination of only 0.03 lx* (color, 1/2s). Since more color data is captured and stored by the camera, you can see things not visible with conventional color video cameras.
* Applies to the VK S274R.
