Closed Circuit Television (CCTV) surveillance is an important tool to successfully monitor premises and deter crime.  A large number of businesses and government agencies use CCTV to monitor and collect video/audio evidence.    

CCTV systems provide surveillance capabilities used in the protection of people, assets, and systems. A CCTV system serves mainly as a security force multiplier, providing surveillance for a larger area, more of the time than would be feasible with security personnel alone. CCTV systems are often used to support comprehensive security systems by incorporating video coverage and security alarms for barriers, intrusion detection, and access control. For example, a CCTV system can provide the means to assess an alarm generated by an intrusion detection system and record the event.

A CCTV system links a camera to a video monitor using a direct transmission system. This differs from broadcast television where the signal is transmitted over the air and viewed with a television. New approaches within the CCTV industry are moving towards more open architecture and transmission methods versus the closed circuit, hard-wired connection systems of the past.

CCTV systems have many components with a variety of functions, features, and specifications. Key components include cameras, lenses, data distribution, power, and lighting, among others. CCTV technologies continuously undergo feature refinements to improve performance in are as such as digital equipment options, data storage, component miniaturization, wireless communications, and automated image analysis. The components, configuration options, and features available in today’s CCTV market create a complex set of purchasing options.


The purpose of security cameras is to capture footage, especially in any vulnerable or high-crime places in and around your building. You have several basic security camera options to choose from:

  • Wired security cameras use cables to transmit footage and conduct video surveillance, but the signal can weaken when the transmission range exceeds 300 meters. Using the appropriate networking cables, switches, and signal boosters can help overcome this problem. Several cameras can be interconnected to a single monitor located in a security room.
  • Analog cameras have been around for years and are still the most common type of CCTV camera installed today. They have basic functionality and store video onsite.
  • IP (Internet protocol) cameras carry out the same functions as their analog counterparts, but with vastly greater capabilities. IP cameras boast sharper, higher resolution images and more flexible features like remote zoom and repositioning. They also give you the option to view footage on a web browser. This makes it possible to receive notifications regarding anything peculiar your cameras records—such as movement inside your business at 3:00 am—and view it live from anywhere via a computer or smartphone. The major drawback of IP cameras is their higher price tag.


All CCTV systems require some amount of cabling, even those with wireless cameras. Cables link different pieces of equipment together, including monitors, recorders, modems, and wired cameras.


When a CCTV camera spots something of interest, a recorder ensures you can go back and view it later. You can set up your cameras to record everything they capture, but that takes up a lot of storage space. For this reason, you may want to program your cameras to record only during certain times of the day or when they detect movement. Your video recording options include DVR and NVR.

  • DVRs, or digital video recorders, are the modern replacement for analog recorders that use videotapes. DVRs capture footage from analog cameras in a digital format at the desired resolution and frames per second. When the hard disk gets full, new images will record over the oldest footage first.
  • NVRs, or network video recorders, work similarly to DVRs, but they’re compatible with IP cameras. Your cameras and NVR connect via a network switch or router. You can easily access footage on an NVR through a web browser or mobile app.
  • A Note about hard disks: Make sure you select surveillance-grade hard disks for your DVR or NVR. These are built with more durable components than regular computer hard drives so they can run 24/7 if necessary.


To view live or recorded footage from your security cameras, you must hook up your DVR or NVR to a TV or monitor. The display unit for your CCTV system can range from a simple monochrome screen to an HD color monitor. If you have IP cameras, you can also view footage remotely from a smartphone or computer.

Types of artificial lights include:

  • Fluorescent–Primarily used for indoor areas in the United States, these lights produce a 60-hertz (Hz) flicker that can interfere with image quality;
  • Incandescent–Include halogen bulbs that are used to illuminate large outdoor areas. Incandescent lights consume more power than other lighting types and are generally the most expensive to operate;
  • High-intensity discharge (HID)–Include high- and low-pressure sodium and metal-halide lighting and are the least expensive to operate. Low-pressure sodium lights produce a yellow light that may distort true color reproduction on video. Metal-halide lights provide the best color resolution. These types of lights require a few minutes to reach their full luminance once turned on.
  • Infrared (IR)–Emit light at a much longer wavelength than white lights, and are faintly visible to the human eye as a red glow or they are not visible at all. IR lighting provides a longer illumination range than white light and can be used for discrete or covert CCTV system illumination. IR light can be provided by light-emitting diodes (LEDs) and lasers as well as filters on incandescent bulbs; and
  • LED–Provide high levels of brightness and intensity. These lights are highly efficient and generate low levels of radiated heat. As such, they are increasingly used in CCTV systems.

It is important to verify the selected lighting technology sufficiently illuminates the area of interest to meet the operational requirements. An overview of CCTV illumination is provided in the Illumination for Closed Circuit Television Surveillance Systems Tech-note. Detailed
information concerning lighting as it applies to security systems is available in the Security Lighting Guide

Benefits of CCTV

To that end, here are more behavior reasons why a CCTV camera is vital for the success of your business.

Benefit #1: Crime Deterrent

The sight of a CCTV camera alone establishes the presence of the law and acts as a serious deterrent to criminals. While it doesn’t necessarily prevent people from carrying out illegal activities, it’s more than enough to make things harder for them to push it through, therefore reducing the crime rate in business districts as a whole.

Benefit #2: Monitor Activities

CCTV cameras enable employers or managers to stay on top of the activities happening at the workplace. By keeping track of the workers and visitors at your site, your company will have the peace of mind knowing they have a full overview of the happenings under the roof of your business.

Benefit #3: Reduced Retail Theft

Installing a CCTV camera on your premises will reduce the likelihood of retail theft as potential shoplifters are at high risk of detection. Even when an item is stolen, it increases the prosecution rates for your business as it enables you to identify suspects at any given time and place.

Benefit #4: Eliminate Fraudulent Insurance Claims

Beyond deterring crime, CCTV cameras also prevent customers from demanding for fraudulent claims against your business. With collective evidence acting as visual and auditory proof, you can use it to your advantage and dispel any misclaims thrown at your company

Benefit #5: Provides Staff Protection

Any false claims against your staff are mitigated with a CCTV camera as business owners will have visual proof of the unedited reality of the situation. It also provides records of deliveries or visitors entering the building, which is essential for keeping track of tasks and ensuring it is done correctly. Additionally, it also protects your staff from potential assaults or misconduct, giving your business some peace of mind knowing that operations are running as smoothly as possible.


  • Quality video evidence helps solve crime and increases apprehensions by private security and police agencies
  • Saves money by identifying operational issues.
  • Acts as a deterrent to those that would consider being dishonest.
  • Video evidence often eliminates or significantly reduces exposure to litigation via fraudulent or frivolous claims.
  • All too often businesses discover products or money missing weeks after the fact. Having video archives available to go back and review often solves these mysteries.
  • Video analytics – let video help the operational side of your business by mapping customer patterns, counting people, capturing license plates and more.
