Get The Most From Your CCTV System 


The use of recording closed circuit television (CCTV) surveillance systems is an established procedure for commercial institutions, like warehouses, banks, retail stores, convenience stores, and many other types of businesses. Video surveillance systems are an excellent deterrence because would-be criminals will avoid these systems whenever possible. Also, with Security Cameras in place, security personnel are better able to interrupt a criminal act in progress. In the United Kingdom, for example, there has been an explosion in recent years of CCTV surveillance in public and common areas such as town centers. Britain now boasts of employing the most extensive video surveillance systems anywhere in the world.  Recent research conducted by the Violence Research Group, University of Wales College of Medicine determined that surveillance was associated with increased police detection of violence, and with reduction in numbers of people injured in assault. 

CCTV PERFORMANCE TIPS 

  • It’s important that you have sufficient number of well-placed security cameras to allow for sufficient detail and coverage of the area you are protecting.
  • Ensure there is adequate and proper lighting in the target areas.
  • Business owners should have written procedures and all involved personnel should be trained in how to react to a criminal event.
  • Businesses should create and adhere to a regular system maintenance program.
  • In order to facilitate possible prosecution, any recordings made by the video security system that capture a crime must be preserved in a way that enables police to document a chain of custody of the original images.

 DESIGNING YOUR CCTV SURVEILLANCE SYSTEM 

Achieving optimal image quality requires attention to a number of factors that include: 

  • Positioning and choice of lenses, cameras 
  • Types of video resolution
  • Data compression methods
  • Storage space

These considerations are all connected and have to be coordinated. If, for example, you add cameras to a system already in place, you could need to adjust storage amounts and image recording rates from individual cameras. Be sure to make a careful assessment of the physical plant in which the CCTV system will be installed. Analysis of this assessment is a key ingredient of a successfully designed system. Your survey should include a site plan depicting where each camera is placed and what is its viewing field. And don’t forget to test you system to ensure the images it produces will satisfy your purposes.

WHAT TO INCLUDE IN YOUR CCTV SURVEILLANCE SYSTEM  

The list of components for a basic video surveillance system should comprise the following:  

 Your CCTV system should include a monitor so its operation can be checked regularly. Monitors capable of operating in an under-scan mode are highly recommended. This will allow viewers to see and monitor the complete viewing field being recorded. The optimal amount of cameras for an effectiv video surveillance system will vary depending on the size and needs of the owner. Be sure not to position cameras where they can be tampered with. Using concealed wiring will help minimize the likelihood of tampering or disabling. Be sure your cameras’ vision fields are unobstructed and pointed away from bright lights or glare from windows or other shiny surfaces. If bright lights are unavoidable, backlighting cameras can improve image quality.  

Remember: you must include a minimum of one camera at each exit, every customer purchase point and at key areas such as safes. Aim exit cameras toward the inside of the building and all cameras in a way that affords a clear frontal view of the heads and shoulders of anyone who makes a purchase or exits the building. At a minimum, there must be at least one camera for every exit and every customer purchase point.  The lenses on exit cameras should be configured a depth-of-field extending from three feet to beyond ten feet. This will offer the added benefit of providing overviews of the interior and head-to-foot views of people as they enter and exit the facility.  

If installed properly, an investment of a CCTV security system will pay for itself many times over the life of the system. And, of course, your safety and that of your family and employees are priceless.
