are compact, lightweight, attractively designed and most economical line locked random interlace CCTV cameras. They use 2/3' separate mesh vidicon to produce sharp, detailed pictures. Horizontal resolution is 550 lines at center. White clipper and black clamp circuits assure maximum detail without excessive contrast.

Minimum required illumination is just one foot-candle (10 lux). Automatic light compensation circuit accommodates lighting variation of 10,000:1. A mechanical focus adjustment moves the pick-up tube forward or backward to accommodate slight variation in the back focus distance. A front-mounted pilot lamp shows the camera is on.

They are designed for the most popular type of mounting - from the ceiling. If the camera must be mounted on a tripod, the deflection can be reversed by changing a plug internally.

The camera WV-510N: USA standard (WV-510E: CCIR standard) is a weatherproof housing camera designed for a sophisticated surveillance system outdoors or in adverse industrial conditions like heavy rain, direct sunlight, dust, and drastic change of temperature and humidity.

The WV-510N (E) selfcontains a camera unit on a platform which allows easy access to the camera for installation and maintenance. The camera operates in line-locked random interlace and offers clear picture at a minimum illumination of 5 lux. Automatic 30W heater is provided to assure the use of this housing camera even under -20°C temperature. Automatic defroster (electro-conductive glass) is provided on the front glass to assure constant clear pictures.

A sunshield is provided as a standard accessory for outdoor installation where the housing is exposed to the direct sunlight. The housing enclosure is made of alminum alloy for long use. Lens can be selected from among various types: 6.5mm, 8.5mm, 16mm, 50mm fixed focus lens and 14 - 70mm motorized zoom lens model FZ-75M/E.

Sequential switchers are excellent system components for multi-camera security systems. WJ-506 accepts up to six camera inputs; WJ-507 can be used with up to ten cameras.

WJ-506/WJ-507 have two video outputs: sequence and spot monitor. The sequence output displays each camera in sequence. The spot monitor output permits manual selection of any camera for display on a second monitor. The automatic bypass feature of these switchers skips any input with no video signal present; manual selection of bypass is also possible. The length of time each camera displayed during the sequence is manually adjustable froml to 30 seconds. Timing is also controlled externally. A trigger pulse output permits one switcher to control the timing of another unit.

A 12-pin connector at the rear permits selection of the spot monitor output from other equipment. The 12-pin connector also mates with the WJ-800 time/date generator to display the number of the camera input as well as date and time. They can be rackmounted into a standard 19" rack.

Deluxe model WJ-510 is an auto alarming sequential switcher. It has all the features of WJ-506, plus alarm mode. It is an ideal mate for the NV-8030time lapse VTR. In addition to six camera inputs, WJ-510 has six input for alarm sensors, such as door, window or mat switches, etc. Each sensor controls one camera. When a sensor is activated, the sequential output automatically switches to that camera and holds on it. A front panel buzzer indicates the alarm condition.

An alarm output, for use with the NV-8030, activates the VTR alarm mode - the VTR changes from low speed to normal speed. WJ-510 stays in the alarm mode until it is reset manually, externally or automatically. WJ-510 can also reset the VTR alarm mode to return the NV-8030 to its low speed. It can be rackmounted into a standard 19" rack.

Active switcher is compact system component for studio CCTV systems. Twelve inputs can be switched to a single video output. Switching is accomplished during the vertical interval. The non-locking pushbuttons light up to show which input has been selected. For added flexibility, inputs are Hi-Z looping with BNC connectors. It can be rackmounted into a standard 19" rack.

WJ-800 is a time/date generator which superimposes the time and date onto any composite video signal. WJ-800 produces white characters with edges outlined in black. Front panel switches control character size (26 or 36 TV lines high) and arrangement of date and time: on the same line or one above the other. Front panel adjustments allow the display to be positioned within 80% of the picture area. When used with sequential switchers (models WJ-506/WJ-507/WJ-510), WJ-800 also displays number of camera input. Time accuracy is determined by the power line. An internal full automatic calendar circuit changes the day, month and year automatically- and even makes allowances for leap years! It can be mounted into 19" rack.

The NV-8030 time lapse video tape recorder is especially designed for closed circuit security applications. Its true time lapse system records 10, 20, 40 or 80 [9, 18, 72 or 108] hours of black-and-white pictures on a single 7" reel (732m) of 1/2" video tape. The VTR can also operate at the normal 163.22 mm/sec [7 1/2 i.p.s.] speed [in accordance with the EIAJ #1 black-and-white standard VTR's].

An outstanding feature of the NV-8030 is its ability to record and play back perfect still frames by means of its 1 SHOT mode. It can record a single picture (one TV field) manually (by closing the 1 FIELD button) or by external control (by closing a switch connected to the 1 SHOT input terminals). This mode permits highly efficient information storage using the video tape medium. In fact, the VTR's maximum recording time can be greatly extended in the 1 SHOT mode by using a timer to provide momentary contact closure at specified intervals: for example, closure at 14.4 [12] second intervals yields a recording time of about one month.

This feature makes the NV-8030 an excellent replacement for film in scientific research applications that require time lapse photography. The 1 SHOT mode can be used for still frame playback, for detailed analysis of recorded material. The VTR plays back a single picture when the 1 FIELD button is pressed.

Pressing the button again advances the tape to the next field. The 1/3 FIELD button may be used to eliminate any picture noise on the screen and obtain a perfect still frame picture. Users with sophisticated security systems will appreciate NV-8030's alarm system. Designed to mate with National's WJ-510 Auto Alarming Sequential Switcher, it can also be used with its own alarm sensors.

WV-7490 is a remote control unit for indoor pan/tilt mechanism head WV-7230 and outdoor pan/tilt mechanism head WV-7260. WV-7490 requires relay box WV-7435 (for indoor use), or WV-7465 (for outdoor use). It controls power on/off (24V AC) for camera, zoom lens, defroster and wiper for outdoor housing, and pan/tilt mechanism. It controls 6 sets of zoom lenses, housings and pan/tilt mechanisms in selection. It can be mounted into a standard 19" rack with accessory rackmount adaptor.
