The Basics of CCTV Cameras

When an individual decides to increase the surveillance efforts for their home or business, there are different technologies to choose from. CCTV cameras have been around for decades, and function as one of the most simple, effective security methods. To figure out if CCTV cameras are the right choice for a home or business, owners should first understand the basics behind this technology.

 

According to Bosch Security, a CCTV security system play an integral role in the detection, recognition and identification of a security-related incident. While CCTV cameras may seem complex, they are usually comprised of only three parts: the lens, which gathers light reflected from the object or subject in view; the image sensor, which converts the light image into electronic signals and the image processing circuitry, which organizes, enhances and transmits the electronic signals. Together, these three components make video surveillance possible, and give users the ability to choose between color, monochrome and day/night technologies. CCTV cameras' color options allow the system to adapt to different situations, and each has its own unique advantages. These include:

  • Color: Better overall representation of the monitored area, with proper lighting, that can help authorities identify a suspect on tape more easily
  • Monochrome: Higher resolution in lower lighting and a less expensive operating cost
  • Day/night: A combination of color and monochrome that can be used for both indoor and outdoor monitoring
 

One of the most attractive features of CCTV cameras is their customization. To meet specific needs, people can choose to tailor the following features:

  • Image quality, stemming from high- or low- sensitivity during image processing
  • The field of view each camera will cover
  • The use of natural or artificial light to generate the most visible conditions
  • The cameras' source of power
  • The environment where the equipment will be installed, as CCTV cameras can be useful both indoors and outside
  • The type of lens, which can be fixed focal length, varifocal, monitored zoom or IR corrected lenses, among others
  • The iris - or amount of light reaching the image sensor - which can be fixed, manual, electronic or aperture
  • Signal-to-noise ratio
  • Amount of backlight compensation, or the amount of light behind the object or person-of-interest in view
  • Manual or automatic adjustments

As CCTV cameras can be adapted to meet most security needs, they make a great security addition to homes and businesses across the country.
