CCTV ELEMENTS SYSTEM

SIX DESIGN CONSIDERATION

1. Enviromental picture taking

2. Camera Lens

3. Transmission media

4. Monitor

5. Video signal management

6. Controller equipment

LIGHTING

Without light in point camera can't perform task with every consideration which is give desirable image

Based on lighting, available 2 camera types :

– FULL VIDEO :

– USABLE VIDEO

LENS

Lens are optical component of system that describe picture screen include size, form and focus.

Three factor of quality lens influence

1. Glass Absorption factor

2. Coating and Polishing

3. Mechanism

LENS SELECTION

STEP FOR LENS SELECTION

1. Picture taking place identification, (to estimate with lens, broad estimation / vertical high picture taking)

2. Distance estimation of camera goes to picture taking place

3) Focal elongated computing of lens

4) Estimate horizontal's dimension and vertical area view critical

5) Determining area view critical measure in monitor

6) Choose for lens the most approaches requirement

CAMERA

QUALITY DETERMINANT AND REABILITY OF CCTV SYSTEM

Image censor resolution Signal Comparation to noise Automatic light compensation Synchronization Output signal Environmental conditions and camera reability Dimensions and weight

MONITOR

Display ( monitor) criteria grouped in two category :

Electronics factor

Human interface factor

3 parameter that regard operator ability is engaged monitor efficiently :

Display size

Operator distance goes to to monitor = (Measure monitors (in inchi) – 4 = optimum visibilities +/- 25% (feet)

Viewpoint

There is 3 type Monitor that frequent being used by various excess and its lack

CRT

LCD

Plasma
