The TSN-410D series of digital signal processing CCD color video cameras offers better picture quality and on-screen display, more than 470 TV (H) lines of resolution and is factory-programmed, according to manufacturer Elmo Mfg., New Hyde Park, N.Y. The series features automatic or manually selectable three-zone photometric back-light compensation and is available with three power sources: the TSN410D (24v AC); the TSN-411D (12v DC); and the TSN-412D (120v AC). Other features include minimum illumination of 2.2 lux at F1.2, auto gain control, auto iris for DC and video and a CS/C lens mount with optional adapter ring.

Los Angeles-based International Protection Security Systems has made a foray into remote video monitoring with the introduction of Instant View SD-300XL. The system turns a modem-equipped PC into a remote video monitoring system. Audio can be added using a DSVD modem, and the system can be customized to monitor multiple sites.

VideoVoice version 2.1 is the latest version of VideoVoice 32, a "look in and listen in" video event monitoring system. From Extreme Video, Mt. Clemens, Mich., the 32-bit hardware and software program defines the type of event that will cause the system to alarm and capture video and defines where the information will be sent. An alarm or event can be sent via telephone lines to a Windows 95 computer with VideoVoice software and modem. The receiving computer can view video and remotely control doors, lights and alarms. Hardware is installed in a PC at the sending location, and cameras, motion detectors and alarms are connected to the system's card. Other features include network compatibility and background multi-tasking. The system supports from one to hundreds of cameras, according to Extreme Video.

A compact corner camera made of stainless steel and equipped with 24 LED infrared illuminators discreetly lights up a room 50 feet deep, says manufacturer Extreme CCTV Surveillance Systems, Burnaby, B.C., Canada. It features an armored glass view plate, vandal-resistant screws and a polycarbonate filter that blocks light outside of the chosen infrared spectrum. The infrared illuminator operates at a center frequency of 940 nm and is undetectable to the human eye, says the company. The camera can be powered from a single 1 amp, 12v supply.

Mounted on a telescoping fiberglass pole, the TreeTop Peeper, an elevating video inspection system from Christensen Designs, Manteca, Calif., can peer over 50-feet-high objects. Designed to perform safe surveys, the 6-ounce micro camera can enter 1.2-inch diameter openings and scan low-light environments, according to the company. Images can be displayed on a 3.8-inch diagonal ground level LCD monitor or documented on an optional Sony EVO-220 VCR. The system weighs less than 16 pounds, and a color camera is optional.

Targeting demand for accurate color reproduction in low-light applications, Sony Electronics, Park Ridge, N.J., has introduced the SSC-DC50 and SSV-DC54 cameras. The digital signal processor cameras feature Smart Control technology, which automatically adjusts white balance, a 1Ž3-inch HyperHAD CCD chip, 470 lines of horizontal resolution and a signal-to-noise ratio of 50dB. A wide-range CCD iris function (1Ž60 to 1Ž100,000 second), light level control and a selectable turbo AGC feature for sensitivity of 1.9 lux at f1.2 provide enhanced capabilities, according to the company.

Also new at Sony is the SSC-CX34 camera with an integrated 12X zoom lens. Weighing about 1 pound, 2 ounces and measuring 5.5 inches, it can fit a light-duty pan/tilt head and a small dome housing. It also features a digital signal processor, a 1Ž3-inch HyperHAD CCD chip, 470 lines of horizontal resolution, a signal-to-noise ratio of 50dB and Smart Control technology.

Two 24-hour industrial time-lapse recorders are new from Chugai Boyeki, Commack, N.Y. The real-time (CTR-024NC) unit records at 20 fields per second and the time-lapse (CTR-024N) unit at 5 fields per second. Both units are compact (10.9 inches wide) and offer key-operated mode lock, alarm recording, time and date generator, auto repeat recording and alarm search capability.

TC3924 video cassette recorders from Philips Communication and Security Systems Inc., Lancaster, Pa., provide video/audio record and playback in 6- 18- and 30-hour recording using T-120 tape and 8-, 24- and 40-hour recording using T-160 tape. The TC3924X provides 9- and 27-hour video and audio recording using E-180 tape. Features include alarm recording, alarm search, a program timer and a security lock for the recorder's controls.

The American Dynamics ADTT keyboard integrates with American Dynamics matrix switcher/controller systems to provide access to video switching options - from camera and monitor control to advanced automatic functions, according to Sensormatic Electronics Corp., Boca Raton, Fla. The unit's tracker ball controls fixed and variable-speed pan/tilt units and dome cameras. Its keyboard buttons control lens functions, and an LCD display is included.

The CyberDome from Kalatel, Corvallis, Ore., is available in a 6-inch flush mount housing. It features a pan/tilt drive, quick-release connectors, plug-and-snap circuit cards, twist-on dome attachments and variable pan/tilt/zoom speeds of up to 400 degrees per second. Programming features include auto iris control with manual override, programmable camera tours, proportional zoom speeds, return-to-home position and programmable auto-pan and preset tour speeds. CyberDome integrated cameras come with a programmable 2-8x electronic zoom in addition to a 12x zoom lens.

The KV Series of VCRs from Toshiba Security Products, Irvine, Calif., is led by the KV-8960, a high-density, time-lapse recorder with 13 recording speeds, including 24-hour virtual real time. High-density technology gives the recorder triple-density recording and playback capabilities, says Toshiba.

K4 multiplexers from Vision Research Corp., Ringwood, N.J., are available in simplex or duplex, color or monochrome, and 8- or 16-camera configurations. Features include activity detection, 2x electronic zoom, looping inputs, dual monitor outputs, multi-scene displays, menu programming, programmable AGC, alarm handling and history log, VCR step pulse interface, automatic camera synchronization, SVHS (Y/C) VCR connection, RS-232 and RS-485 com ports and NTSC/EIA and PAL/CCIR compatibility.

The 135V Video/Control Data System supports the transmission of two channels of video from cameras to monitoring stations and vertical interval control signals back to pan/tilt/zoom lens controls - all over one multi-mode fiber, says manufacturer Fiber Options, Bohemia, N.Y. Level/loss indicators are provided on the transmitter and the receiver for use in determining received optical power. The transmitter also includes video status indicators. The system interfaces with Burle, Pelco, Robot or Vicon's "up-the-coax" systems.
