Wide dynamic range

When a surveillance scene includes bright and dark areas, alternate images are captured at optimum exposure for both levels of illumination, and the resulting two fields are combined into a single frame. This produces clear, glare-free images in a variety of lighting conditions, such as entrances with varying levels of indoor/outdoor illumination and situations where backlighting can make it difficult to identify facial features.

Progressive scanning

Conventional surveillance camera systems using interlaced scanning are not capable of producing clearly identifiable images of moving cars or people. The interlace method uses two scans to create a single image frame, producing jumpy, poorly defined images when still images are pulled from the video feed. Progressive scanning incorporated in the Hitachi VK-S654N/EN records the frame in a single sequential scan, creating sharp, high resolution still images, with clearly defined lines and contours.

Electronic image stabilization

Based on Hitachi’s track record of pioneering image stabilization technology, electronic image stabilization compensates for vibration or movement of the camera, automatically minimizing image blur.

Outstanding color reproduction

Advanced digital signal processing ensures outstanding color reproduction. Characterized by superior ability to accumulate available light, the high-performance CCD produces sharp, clear

Digital output ensures exceptional image quality

The Hitachi VK-S654N/EN relies on digital output to ensure lossless, noise-free image data, maximizing camera performance and preserving the exceptional quality of captured images.

images even in challenging lighting conditions. And accurate color reproduction enhances security performance in a variety of surveillance scenarios. This digital surveillance camera can capture details such as facial features, clothing, and automobile colors clearly and accurately, producing true-to-life surveillance images that can serve as vital evidence.

Hitachi’s frame noise reduction minimizes random noise and after-images often associated with moving subjects, making this high-performance unit suited to a variety of surveillance scenarios. Producing clear, sharp images even in challenging low-light conditions, this technology also facilitates image compression in network camera systems.

Digital slow shutter

Digital processing boosts sensitivity to a maximum of 1/1 second exposure time, making it possible to capture bright, clear images in a variety of lighting situations.

Images are captured in full color. IR cut filter off.

The degree of the removable IR cut filter’s effectiveness varies with the type and intensity of the light source.

In daylight conditions, the IR cut filter ensures clear, high- quality color images. At night or in other very low light situations, the IR cut filter is automatically removed to allow capture of bright, high-contrast black and white images.

This function makes it possible to mask the camera’s view of areas subject to privacy concerns, such as windows and entrances. The position and size of the mask is maintained, even when the camera pans, tilts or zooms, making this unit particularly suitable for surveillance of public areas.

Motion detection

This function triggers an alarm when motion is detected in designated areas of the surveillance frame. Motion detection can be activated in as many as eight frame blocks out of a total of 64.

Monitored Images

Images can be flipped verti- cally or horizontally, enabling tracking of subjects moving underneath the camera in a single continuous shot.

The RoHS-compliant VK- S654N/EN meets guidelines for permissible levels of lead, mercury, cadmium, hexa- valent chrome, PPBs and PBDE, making it an eco- friendly way to implement high-tech surveil-lance.

Compatibility facilitates system upgrades

The VK-S654N/EN offers effortless upward compati- bility with the VK-S654R/ER, making it easy to upgrade and incorporate the latest technical advances in your surveillance systems.
