A small business security system can provide you with the same big business security department coverage at a fraction of the cost. Small businesses have security concerns just like a large business but normally can’t afford the expense for a separate security department and personnel. A small business security system is the solution to your problem.

A small business security system has several benefits:

  • It is reasonably priced and “small business” affordable
  • It eliminates the expense for additional personnel
  • It can provide 24 hour 7 days a week coverage
  • If real-time monitoring is desired, one individual can do it
  • It can cover both the outdoor and the indoor environments of your business

Modern technological advances in the security camera industry have made small business security systems incredibly versatile in application while at the same time maintaining reasonable prices. In addition, small business security systems are component systems, so as your business grows, your system can grow as well.

A basic small business security system is a component system consisting of one to several digital video cameras, a processor or capture board, a monitor, and a digital video recorder or DVR. Since the system is a component system, each component can differ in application or type while maintaining the function of the entire system. This means each component can differ to fit your particular application while still maintaining the function of the system.

Another advantage of a small business security system is its broad application potential. Not only can a system be designed to provide external or perimeter coverage, but the same system can provide internal office or store coverage as well. Further, the system can be a stand alone system or in can incorporate one or more personal computers. This means you monitor your small business in a separate area at your business location or anywhere in the world where there is internet access.

Here is a brief description of just some the additional features/options that are available on small business security system cameras:

Small business security system digital video cameras can be indoor or outdoor cameras. Outdoor cameras are basically the same as indoor types except they are protected from weather and other environmental elements by a case or enclosure. Outdoor cameras usually are rated as to their degree of protection using an International Electrical code standard called an Ingress Protection rating. Outdoor cameras should be at least an IP66 or IP67 rating which means they are completely “dust tight” and can withstand powerful jets of water, or in the case of an IP67 rating, can even be submerged in up to one meter of water.

Cameras normally use a coaxial cable that is run from each camera to the processor to transmit the video image. If cabling is impractical or undesirable, wireless cameras are available. A wireless small business security system takes advantage of the 2.4 or 5.8 GHz radio band technology to send its video data to a corresponding receiver.

Cameras can be purchased for special lighting conditions as well. Day/night vision cameras can produce a high quality color video image in normal lighting conditions and in settings where there is very little visible light. If you need coverage in rooms or areas of total darkness, a night vision infrared (IR) camera may be the solution. These cameras use infrared illumination from IR Light Emitting Diodes or LEDs to “light up” the target area. The IR light is seen by the camera but is invisible to the human eye.

Additional camera options include:

  • Audio recording
  • Pan, Tilt, and/or Zoom (PTZ) options
  • Networking capable via the internet
  • Hidden or disguised cameras

A small business security system needs a processor, monitor, and recorder. Personal computers can be used for this purpose but standalone systems are also available. A typical standalone system contains the processor and DVR in the same unit much like a desktop computer. The security monitor, again much like a computer monitor, connects to the processing unit. Files are saved on the DVR in standard digital video formats so they can usually be viewed by personal computers and most media devices or copied if necessary to give to police or used as evidence.

A custom designed small business security system can provide you with “big business” security at a fraction of the cost. The systems are not only affordable but versatile enough to be used for almost any application.

CCTV Video Security Surveillance Equipment

CCTV video security surveillance equipment or closed circuit television video security surveillance equipment can provide all of your security and monitoring needs. Contemporary CCTV video security surveillance equipment offers several features and great versatility along with affordable prices that make this equipment and excellent choice for business and residential applications.

CCTV video security surveillance equipment consists of a few basic components that make up the security systems. Each of these components offers convenient and often highly technologically advanced features that create the versatility of the system such that the equipment can be used for nearly any situation or application. In addition, there are several additional components that can be added to a basic system with ease.

Basic CCTV video security surveillance equipment consists of the following five items:

  • Digital video camera(s)
  • A processor or capture board
  • A monitor
  • A digital video recorder or DVR

Probably the most important component is the digital video camera. Digital cameras for CCTV video security surveillance come in a variety of types, sizes, and functions. Cameras can be classed as either indoor or outdoor cameras. The major difference between the two is that outdoor cameras are built within a casing or enclosure that protects the sensitive electronic components of the camera from the weather and other environmental elements.

These cameras often contain an International Electrical standard code rating that provides the user with a description of the ability of the camera to withstand penetration by liquids and particles. This rating known as an Ingress Protection code or IP code is normally an IP66 or an IP67 for an outdoor CCTV video security camera. IP66 means that the camera is impervious to dust and that powerful water jets from any direction shall have no harmful effects. A rating of IP67 means the camera is impervious to dust and can be submerged in water up to 1 meter in depth.

CCTV video security surveillance equipment cameras can be purchased with other specialized features. Most of these features are based upon recent technological innovations and may increase the cost of the camera depending on the feature and its range of function but are well worth the expense.

For example, most CCTV video cameras create video using a small sensor chip called a Charged Coupled Device or CCD. The CCD converts the light transmitted through the camera lens into an electrical charge that can be detected and used to create high quality digital video. Some CCDs are so sensitive that they can produce high quality video with very little visible light. These cameras, are called day/night vision cameras. Other cameras, called Infrared (IR) night vision cameras can produce a high quality color image when there is visible light present and can produce a high quality monochromatic or black and white image under total darkness conditions when absolutely no visible light is present.

Other features that can be included on CCTV video cameras include a pan, tilt, and/or zoom function, the ability to record audio, and the ability to transmit the video signal from the camera to a receiver using radio waves.

Pan and tilt functions permit the camera to be moved in different directions allowing the camera to cover a wider area of view than one that is stationary. Using pan and tilt functions, one camera may be able to cover the area that may take two or three stationary areas to cover. The zoom function also allows the camera to take advantage of enlarging the field of view, much like a telephoto lens. Cameras can be purchased with the individual pan, tilt, and zoom functions or they can be offered collectively, often referred to as PTZ cameras.

PTZ cameras can be controlled manually, by remote control, and by programming. Programming functions for PTZ cameras can provide automatic tracking functions when utilized with automatic motion detection. For example, the camera can follow a car traveling through a parking lot or an individual in a specific area.
Wireless CCTV video security surveillance equipment normally uses the 2.8 MHz or 5.8 MHz radio band to transmit the video image from the camera to the receiver, which then sends it along to the processor. Cameras come with built-in antennas and circuitry that send the images.

CCTV video security surveillance equipment has seen tremendous technological improvements in just the past few years making the equipment versatile and affordable for just about any application.
