CLOSED CIRCUIT TELEVISION SYSTEMS This section of the manual contains information about Javelin closed circuit television (CCTV) equipment. Although E.P.S. has access to equipment from most all CCTV manufacturers, the Javelin equipment line is certainly representative of what is available on the market today. The Javelin equipment is fully interchangeable with most other equipment lines from  the leading manufacturers.

CCTV systems are undergoing dramatic changes at this time. Care should be taken when designing a new system or when selecting specific equipments to interface with an existing system.  The use of digital electronics has almost completely eliminated the use of analog devices in most CCTV systems. Analog equipment should be considered for replacement of existing analog equipment, but most new systems should utilize only digital equipment.

Microchip-based cameras are now available for both interior and exterior applications that can operate within a 5-inch diameter dome. These compact domes can pan / tilt / zoom at extremely high rates of speed with great precision and reliability. They are very ”low profile” and as a result, aesthetically pleasing.

 In an alarm programmed, preposition mode, the high-speed dome cameras can respond automatically to any alarm input in pan/tilt/zoom functions in less than 1.5 seconds. This rapid response capability has greatly improved the use of video tracking systems for curtailing retail theft and shoplifting activity.

 Most cameras use color technology, even for viewing at night. Javelin has a product line that uses color to a certain minimum light level, at which time the camera switches to a monochrome mode. This concept has received wide acceptance as a cost-effective solution to critical low-light level applications.  

Digital multiplexers and recorders are now widely used to provide simultaneous monitoring and recording of up to 16 cameras per device. Multiple units can be integrated to provide CCTV systems with up to 128 cameras. Remote monitoring (live), storage, and control of CCTV systems is also available using PC - based processing equipment. The Javelin remote system is called ”Rapid Eye”. Rapid Eye utilizes a standard PC - based computer system to access and store the CCTV data. The use of Rapid Eye with a laptop computer can provide access to any CCTV system from almost any location.

Installation of CCTV systems has become easier in recent years. The increased number of CCTV systems has helped the industry dramatically by providing more manufacturers with the opportunity to produce better equipment and to standardize on installation procedures. Coaxial cable and glass fiber is used for most video transmission between the camera and recording/monitoring equipment. A small percentage of applications utilize TX lines and microwave for video transmission. Digital technology improvements have helped to make all of these concepts provide higher resolution pictures at reasonable costs.

The cost, reliability, and acceptance of fiber optic cable has improved dramatically in the last few years. The use of fiber optic cable for video transmission within a large building complex is now commonplace. Any video run of 500 feet or more should use fiber optic cable for the most cost effective approach.
