Electrical Symbols — Semiconductor

Semiconductors are crystalline or amorphous solids with distinct electrical characteristics. They are of high resistance — higher than typical resistance materials, but still of much lower resistance than insulators. Their resistance decreases as their temperature increases, which is behavior opposite to that of a metal. Finally, their conducting properties may be altered in useful ways by the deliberate, controlled introduction of impurities into the crystal structure, which lowers its resistance but also permits the creation of semiconductor junctions between differently-doped regions of the extrinsic semiconductor crystal. The behavior of charge carriers which include electrons, ions and electron holes at these junctions is the basis of diodes, transistors and all modern electronics. 26 libraries of the Electrical Engineering Solution of ConceptDraw PRO make your electrical diagramming simple, efficient, and effective. You can simply and quickly drop the ready-to-use objects from libraries into your document to create the electrical diagram.

CCTV Surveillance System Diagram. CCTV Network Diagram Example

Creating CCTV system diagrams is quick and easy with ConceptDraw PRO diagramming software enhanced with Audio, Video, Media solution from ConceptDraw Solution Park. It contains library of vector cliparts of video and TV devices and different digital gadgets for drawing this kind of diagrams.

CCTV Network Diagram Software

The CCTV is the process that carried out using the video cameras for transmitting the signal to the specific location, on the limited set of monitors. We are talking about the video cameras that are used for monitoring on such guarded objects as airports, banks, stores, military objects, etc. CCTV equipment is also used in the industrial installations, for surveillance in the public places, for recording the video on the digital video recorders.

Physical Security Plan

ConceptDraw PRO diagramming and vector drawing software extended with Security and Access Plans Solution from the Building Plans Area of ConceptDraw Solution Park is a powerful software for fast and easy drawing professional looking Physical Security Plan.

How To Create CCTV Network Diagram

Closed-circuit television (CCTV) uses cameras and monitors to carry out video surveillance. Unlike broadcast television this system has only local signal. It is a feature of almost every video camera, yet CCTV is mainly a system for visual control of certain areas such as banks, airports, supermarkets, and other places for security reasons. Developing and installing CCTV system is a time-consuming process. It also requires certain knowledge and skills. ConceptDraw is a solution of setting video cameras rationally. You can achieve two aims at once: CCTV Design Tool saves your time and your money and helps you make professional video surveillance system.
