Video Synchronization Distribution Amplifier

TM 5-6350-275-10

(5) Video Synchronization Distribution Amplifier . The video synchronization distribution amplifier distributes a

synchronization signal to video cameras where camera synchronization is required. (6) Video Storage Units. The Video

Cassette Recorder (VCR) is a time lapse recorder. It is capable of recording for 720 hours on a single cassette tape.

The alarm event record time is selectable for up to 3 minutes of automatic recording. Playback functions include: alarm,

fast forward, search, fast rewind search, rewind/fast forward, play, slow motion or step field/frame, and pause/still.

(7) Fiber Optic Hardwire Interface. The fiber optic hardwire interface converts a fiber optic video transmission

medium to a hardwire transmission medium for the video switcher input.

e. Uninterruptible Power Supply (UPS). The Uninterruptible Power Supply (UPS) provides true computer grade

power upon loss of line AC. The microprocessor determines which system mode it should operate in depending upon

line conditions. The Uninterruptible Power Supply (UPS) can also be operated manually through the control panel.

(1) Auto Mode. In auto, the microprocessor monitors the quality of input power and regularly tests its batteries and

inverter. The battery charger keeps the batteries at full voltage.

(2) Inverter Mode. If the microprocessor senses a problem with line power, it switches to inverter mode. The

inverter takes dc power from the batteries, converts it into ac, conditions it, and provides computer grade power to the

supported system.

f. Entry Control Equipment . Entry control equipment provides the mechanism for automatically unlocking doors

when authorized personnel wish to enter or leave a particular area. ICIDS can use three types of access control devices.

The first, and most commonly used, is the Intelligent Access Unit (IAU). It is normally mounted on a wall adjacent to

each door. Personnel are issued an identity card, which they present to an access reader each time they wish to enter

and/or leave a protected area. Details of each access are recorded by the system and all attempted breaches in security

are reported to operators by means of system alarms.

The second type of access control device is called a key pad. Personnel use it to enter 6 digit Personnel

Identification Ciphers (PlCs) and/or 4 digit Personnel Identification Numbers (PINs). It can operate as a stand-alone unit,

where the entry of a valid Personnel Identification Number (PIN) unlocks the door. It may be linked to an access reader

so that. access is only granted when both a valid card has been presented and a valid Personnel Identification Number

(PIN) is then entered. Each person is allowed up to three attempts to enter the correct Personnel Identification Cipher

(PIC) or Personnel Identification Number (PIN), after which the system reports details of the incident to the control center

by means of a system alarm.

The third type of access control device is called an access reader. The use of access readers allows for two optional

features of the ICIDS system, called Accountability and Messaging. Accountability enables the current location of all

authorized personnel to be recorded by monitoring their access into and out of each protected area. Operators can

create displays which list the personnel within each protected area and may also review the movements of an employee

on a particular day or during a selected time. Messaging is an option which permits the System Administrator to send

messages to a card holder or a group of card holders.

1-15. ACCESS CONTROL.

a. General. Access Control is the ability to control and monitor the entry and exit of personnel. This is achieved by

access readers which nlock doors when a person presents a valid card and/or enters a valid Personnel Identification

Number (PIN). Information for the use of each access reader and door is
