Security Cameras vs Surveillance Cameras: Pros and Cons

You don't need a technical background or even a very comprehensive knowledge of how each of the components operate. But you do need to know what each component does and what its requirement is.

In this guide, we will describe most of the common closed circuit television components and supplementary equipment, and provide guidelines for their selection. While other supplemental components may be added into more complex systems, the camera, monitor and video cable form the core of all CCTV security systems.

The Camera The camera is the eye of the system. Its only function is to provide a view of the site under surveillance by sending an electronic signal along a video cable. It is passive, it only views the scene similar to the human eye. Tube cameras are no longer used for a few reasons. Tubes wear out, are fragile, more expensive, and cannot match the versatility of the CCD Charged Coupled Device or 'chip' camera. To date, not one camera has needed replacement due to worn out parts, degraded video output, or any other defect in the camera itself.

Our return service on a completed install is. This is due to quality equipment, proper placement, and a well trained sales and technical staff. The Monitor The monitor receives the signal sent by the camera and converts the signal into a picture on a television screen. At least one monitor must be provided at each viewing station in the CCTV system in order to see the view provided by the camera s. The Cable The cable required for a basic system is 75 ohm coax cable.

Each camera is connected by an individual cable to a switcher, and only one cable runs from the switcher to the monitor. This is because only one video signal can be transmitted on any monitor at any one time. The viewer uses the switcher to determine which camera's video signal will be sent onto the monitor and displayed on the screen. The viewer may make the selection manually or program a sequential switcher to automatically change from view to view.

In security CCTV systems with a large number of cameras, it is usually desirable to divide the cameras into groups and use a second switcher and a second monitor to provide views of the different areas. Cameras The first criteria for selecting a camera for a CCTV system is the minimum light level the camera must operate in. This criteria remains constant regardless of whether the camera is mounted indoors or outdoors. CCD cameras can be divided into three classifications of operation based on lighting considerations.

These three classifications are listed with descriptions of the levels of light. General Purpose Cameras - Most general purpose cameras will work well indoors. Light levels must remain relatively high and evenly illuminated to effect a good quality picture. With out the aid of auto-iris lenses or infrared illumination. Low Lux Cameras - A low lux camera can in some instances 'see' with the illumination from a single lit match. In reality, CCD cameras see well in the infrared spectrum.

A low lux camera is any camera with a lux level of light measurement below 1 lux. A lux of. Color Cameras -Color cameras require an enormous amount of light compared to a black and white camera. A color camera would work well indoors with bright illumination. Outdoors, high intensity lights 75 to watts would be needed at night to reflect the colors back on to the camera. Daytime light usually is adequate for a color camera.

Monitors Selection and placement of monitors is quite simple, but very important. The only decision is which size to use, and that is determined by the viewing distance. Rayco Security Inc.

10 Different Types of CCTV Cameras and Their Purpose

A closed-circuit television camera can produce images or recordings for surveillance or other private purposes. Cameras can be either video cameras , or digital stills cameras. The main purpose of a CCTV camera is to capture light and convert it into a video signal. The CCD converts light into an electrical signal and then signal processing converts this electrical signal into a video signal that can be recorded or displayed on the screen. Video cameras are either analogue or digital, which means that they work on the basis of sending analogue or digital signals to a storage device such as a video tape recorder or desktop computer or laptop computer. These cameras can record straight to a video tape recorder which are able to record analogue signals as pictures. If the analogue signals are recorded to tape, then the tape must run at a very slow speed in order to operate continuously.
