CCTV The Fibervision Serial Digital (SDI) video transmission system equalizes the SDI input and provides two re-clocked SDI outputs at the receiver, in accordance with SMPTE 259M, 293M and other similar digital video standards, with speeds of up to more than 360 Mb/s, says maker Communications Specialties, Hauppauge, N.Y. Consisting of a transmitter and receiver, the system is designed for use with multimode optical fiber and supports distances of up to 2 km with no degradation of signal, according to the company. Built-in regulators allow the transmitter and the receiver to operate from low-voltage, unregulated DC power sources.

The TM-1040 CCD is a 30 frame/second, real-time 1Kx1K CCD camera designed to produce high-resolution, 8-bit digital output and RS-343 or RS-170 analog output, according to manufacturer Pulnix, Sunnyvale, Calif. The digital images produce near-film-camera image quality, and the analog output allows continuous recording in high-resolution format or standard EIA format, says the maker. The progressive scan creates full resolution with automatic electronic shutter or conventional auto-iris lenses.

The NVT Distance Calculator is a pocket-size, slide-rule cable distance measurement tool for CCTV/twisted-pair system installations, new from Network Video Technologies, Redwood City, Calif. Using the calculator and an ohm meter, the length of any 18, 20, 22 or 24 AWG CCTV twisted-pair cable distance can be calculated, says the maker. For a free distance calculator, call 800-959-9870.

Standards-based security monitoring processors for remote surveillance are new from Sony Electronics, Park Ridge, N.J. When connected over ISDN, the RSE-400 and RSE-500 processors can share audio, full-color video and data at up to 30 frames per second. The result is real-time and near-real-time video monitoring of remote surveillance sites, according to Sony.

The Rear Vision system from National Electronics, Houston, includes a compact, 5-inch, black-and-white 12v DC monitor and weatherproof 1/3-inch CCD camera. The camera and monitor are connected with a single cable that handles power and video. The system is suited to trucks, buses or any type of vehicle with limited rear vision, says the maker. It acts as a supplement to the rear-view mirror and includes a day/night switch to reduce glare from headlights pointed toward the camera. The camera is also suited to other commercial applications, according to National Electronics.

The model IK-628A from Toshiba, Irvine, Calif., is a "hybrid digital/analog camera," featuring Digital Plus, a design based on traditional analog processing that is enhanced via digital control. According to Toshiba, the analog element helps the camera deliver accurate video images with a near-infinite number of colors and shades of gray; and digital control provides the means for color consistency in every camera manufactured.

A new line of smoked domes for use in drop-ceilings has been introduced by Brossard Co., Woodstock, Ill. The domes are available in various sizes and styles. Nine-, 12- and 22-inch domes are supplied with light shield and 24-inch, drop-ceiling tile. The light shield prevents people from detecting the presence of a camera behind the dome, so live and decoy domes can be intermixed, according to Brossard.

The Remote Video Transmission Unit from Exxis Security, a division of Ultrak, Lewisville, Texas, includes a four-input video transmitter plus a remote monitoring software package. Designed to work exclusively with Exxis observation systems, the unit gives users the ability to monitor activity at remote sites via standard telephone lines. The software can be installed on a Windows 95-compatible personal computer, and pictures can be stored for retrieval in other software packages.

CCD computer cameras using the PCI bus are new from Electrim Corp., Princeton, N.J. The cameras use a half-size PCI bus interface card with four parallel input channels of at least 8 bits (256 levels) of gray scale each. With multiplex switching, a second set of four channels is available, allowing up to eight camera heads to be connected to one interface card. For higher intensity resolution and dynamic range, two inputs can be disabled, and the remaining six inputs can be switched from 8 bits to 10 bits (1,024 levels) of A/D resolution. When all four parallel channels are used, the cameras offer a data transfer speed increase of 10 times that of Electrim's ISA bus camera, says Electrim.

California votes to use CCTV at traffic lights

A measure to continue the use of CCTV in fighting red-light running was recently passed by the California State Assembly, in part, because of the legislative tracking efforts of the Security Industry Association (SIA) Government Relations Committee, according to SIA.

The association's legislative tracking program aims to affect the generation and evolution of legislation that has a direct market impact on SIA members. The program follows this formula: track the legislation through the legislative process; research and be familiar with the key pro and opposition legislators; watch the news; devise information faxes with key contact and legislation impact information; and create remedy kits to help SIA members support or fight legislation.

Currently, SIA is working with Department of Transportation Secretary Rodney Slater to assist in his department's recently announced efforts to fight aggressive driving and red-light running.
