Introduction

Introduction

  • Wireless closed-circuit television (CCTV) security cameras are that transmit a video and audio signal to a wireless receiver through a radio band.

  • Wireless cameras are proving very popular among modern security consumers due to their low installation costs and flexible mounting options.

  • wireless security camera allows users to leverage broadband wireless internet to provide seamless video streaming over-internet.


What is cctv

What is CCTV

Closed circuit television(CCTV) system is the use of video cameras to transmit a signal to a specific , limited set of monitors.

It differs from broadcast television in that the signal is not openly transmitted , though it may employ point to point wireless links.

CCTV is often used for surveillance in areas which need security , such as banks, casinos and airports or military installation


Cctv cameras history

CCTV cameras history

  • 1942-first CCTV surveillance system installed by

    German engineer Walter Brush.

  • 1956-first VCR produced by Ampex corporation team

    lead by Charles Ginsburg.

  • 1960-First digital camera signals used in cameras over

    analog by NASA.

  • 1972-First VCR for home use produced by Philips.

  • 1996-First IP camera was released by Axis

    communication.

  • 1998-First consumer digital video recorder s(DVR)

    released to the public.


Types of cctv cameras

Types of CCTV Cameras

Fixed

These cameras provide constant coverage of a specific area.

PTZ

Pan, tilt and zoom (PTZ) cameras cover more ground than fixed

cameras and are quite flexible in their coverage.

IR Day/Night

Day/night CCTV cameras produce images in lowlight and even

complete darkness.

Indoor

Indoor CCTV cameras are ideal for residential, retail and office use.

Outdoor

Outdoor CCTV cameras are encased in weatherproof housing to

protect components from wind, moisture, dust and other

hazards.


Basic components of a cctv system

Basic Components of a CCTV System

CCTV systems are composed of a variety of components for viewing, recording, and archiving video footage that offer a wide range of surveillance benefits.

  • Cameras

  • Monitors

  • Coaxial Cable

  • Digital Video Recorders (DVRs)


Types of cctv system

Types of CCTV System

  • Wired CCTV system-

    It connects the camera to the recording device and monitor with the help of coaxial cables or fiber optic cables The signal transmitted over these cables is then fed to the monitor.

  • Wireless CCTV system-

    In this system a radio transmitter is attached to the camera. A radio receiver is then attached to the input on the monitor system.

Types of wireless cctv

Types of wireless CCTV

  • Analog wireless-

  • Analog wireless is found in three frequencies: 900 MHz,2.4 GHz, and 5.8 GHz.

  • Currently, the majority of wireless security cameras operate on the 2.4 GHz frequency.

  • Most household routers, cordless phones, video game controllers, and microwaves operate on the 2.4 GHz frequency and may cause interference with wireless security camera

  • Digital wireless cameras-

  • Digital wireless is the transmission of audio and video analog signals encoded as digital packets over high-bandwidth radio frequencies.

  • Wide transmission range—usually close to 450 feet .

  • Digital signal means you can transmit commands and functions, such as turning lights on and off.


Basic components of a wireless cctv system

Basic Components of a Wireless CCTV System

  • Wireless Cameras

  • IP Camera and Wireless Antenna/Transceiver

  • Network Video Recorder (NVR)

  • Wireless Access Point

  • Wireless Transceiver

  • Omni-directional Antenna

  • PoE Injectors


Ip camera

IP camera

  • These cameras operate differently than analog CCTV cameras, by sending and receiving data over a computer network and the Internet.

  • IP cameras were introduced onto the video surveillance scene in the 1990s.

  • Today it is being used in residential, school, retail , business and restaurant areas.

Instructions

  • Making the Camera Wireless

    • 1 . Check the back of the camera and look for the "video out" jack.

    • 2. Plug one end of one of the video cables into the camera's "video out" jack and the other end into the wireless transmitter's "video in" jack.

    • 3. Turn the camera and the transmitter on. The camera should begin sending its video signal and images into the transmitter, which should send out the signals via a radio frequency to be picked up by the receiver.

  • Hooking Up to a Monitor

    • 4 . Connect the wireless receiver's "video out" jack to the monitor's "video in" jack. The location of the jack on the receiver depends on the manufacturer.

    • 5. Turn on the receiver and the monitor and set the monitor to its proper video channel. This is usually labeled as "VIDEO" or "INPUT."

    • 6 . Tune the wireless receiver according to the manufacturer's instructions until it is in sync with the wireless video transmitter. The camera's images should appear on the screen.
