INTRODUCTION TO DIGITAL ELECTRONIC SECURITY SYSTEM. INTRODUCTION Digital electronics deals with the electronic manipulation of numbers, or with the manipulation of varying quantities by means of numbers. Because it is convenient to do so, today’s digital systems deal only with the numbers ‘zero’ and ‘one’, because they can be represented easily by ‘off and ‘on’ within a circuit. This is not the limitation it might seem, for the binary system of counting can be used to represent any number that we can represent with the usual denary (0 to 9) system that we use in everyday life. WHAT IS DIGITAL ELECTRONIC SECURITY SYSTEMS? Digital electronics are those electronics systems that use a digital signal instead of an analog signal. Digital electronics are the most common representation of Boolean algebra and are the basis of all digital circuits for computers, mobile phones, and numerous other consumer products. 1. CCTV CAMERA CCTV (closed-circuit television) is a TV system in which signals are not publicly distributed but are monitored, primarily for surveillance and security purposes. CCTV relies on strategic placement of cameras, and observation of the camera's input on monitors somewhere. 2. FIRE ALARM SYSTEM The field of fire detection has advanced to where smoke detectors and alarm devices have combined to become life- safety systems. The purpose of an automatic fire-alarm system is to detect an occurrence, alert the control panel and proper authorities, and notify the occupants to take action 3. IDS SYSTEM An intrusion detection system (IDS) is a system that monitors network traffic for suspicious activity and issues alerts when such activity is discovered.
4. INTERCOM SYSTEM An intercom (intercommunication device), talkback or door phone is a stand-alone voice communications system for use within a building or small collection of buildings. It’s a two-way communication electronic device that contains circuitry for the purpose of transmitting and receiving audio and/or video transmissions. Intercom allows a person speaking into a microphone to be heard on a speaker by people in a different room or area. Intercom have long outgrown the image of the single-line, single-button door buzzer panel. 5. BIO METRIC AND ACCESS CONTROL Biometric Access Control is a system that holds the door for intruders and prevents them from accessing the resources by verifying them as unauthorized persons on the basis of biometrics authentication. Biometric Access Control system works on substantiation. 6. VDP (VIDEO DOOR PHONE) Video door-phone (also known as video door entry or video intercom) is a stand-alone intercom system used to manage calls made at the entrance to a building (residential complex, detached family home, workplace, etc.) with access controlled by audiovisual communication between the inside and outside.
SYSTEM DESIGN CCTV CAMERA  Closed-circuit television (CCTV), also known as video surveillance. Is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors? It differs from broadcast television in that the signal is not openly transmitted, though it may employ point to point (P2P), point to multipoint (P2MP), or mesh wired or wireless links. The first CCTV system was installed by Siemens AG Germany in 1942.
