Colour camera combines performance with small size
The FCB-EX11D camera module from Sony Europe’s Image Sensing Solutions Division is a lightweight, ultra-compact addition to the company’s market-leading range of FCB block cameras. Measuring just 35.9mm x 40.8mm x 59.2mm and weighing only 95g, the PCB-EX11D delivers exceptional picture quality for its size.
The Available in PAL or NTSC versions with up to 440,00 and 380,000 pixel resolution respectively, the FCB-EX11D is based on a ¼-type EXview HAD CCD that is sensitive to near infra-red energy, allowing it to function well in low light conditions. This capability is further enhanced by a slow auto-exposure response, which allows the monitoring of areas where lighting is prone to abrupt changes: for instance in a car park at night.
To ensure conformance to national and international privacy regulations and allow the camera’s use in wide-area monitoring applications, the FCB-EX11D includes an enhanced version of Sony’s established spherical privacy zone masking technology. This includes a mosaic-style masking option, in addition to half-tone and coloured block masks. Masking can be automatically interlocked with the camera’s PTZ operations, regardless of camera angle: the camera automatically adjusts the size of the masked area as the zoom is operated, and can keep masked areas covered even when the camera is circling.
The FCB-EX11D’s on-screen display facilities allow integrators to provide operators with a user-friendly interface, using industry-standard VISCA commands. A high-speed (38.4kbit/s) serial data interface and TTL signal-level control, also using the VISCA protocol, allow easy systems integration. The camera also offers 16bytes of free internal EEPROM space, allowing the storage of data such as product serial numbers and camera/system ID numbers.
With a wide maximum field of view of 46°, the FCB-EX11D offers a wide range of features common to Sony’s FCB family of camera modules. These include an improved built-in motion detection facility and an an electronic flip (E-Flip) function that can invert an image so that it is displayed correctly. This feature is vital in dome systems, to eliminate the need to provide mechanical flip capabilities when an object moves directly beneath the camera.
The module also includes picture freeze capabilities and SMART (Sony Modular Automatic Lens Reset Technology) lens control, a facility that eliminates the need to perform periodical manual resets, dramatically reducing in-service costs. In addition, it provides electronic shutter/slow shutter features, a choice of internal or external sync, and low power consumption of 1.9W with motors inactive.
