CCTV System


CCTV (closed circuit television)

CCTV (closed-circuit television) is a TV system in which signals are not publicly distributed but are monitored, primarily for surveillance and security purposes.

CCTV relies on strategic placement of cameras, and observation of the camera's input on monitors somewhere. Because the cameras communicate with monitors and/or video recorders across private coaxial cable runs or wireless communication links, they gain the designation "closed-circuit" to indicate that access to their content is limited by design only to those able to see it.

Older CCTV systems used small, low-resolution black and white monitors with no interactive capabilities. Modern CCTV displays can be color, high-resolution displays and can include the ability to zoom in on an image or track something (or someone) among their features. Talk CCTV allows an overseer to speak to people within range of the camera's associated speakers.

CCTV is commonly used for a variety of purposes, including:-


  • Maintaining perimeter security in medium- to high-secure areas and installations.
  • Observing behavior of incarcerated inmates and potentially dangerous patients in medical facilities.
  • Traffic monitoring.
  • Overseeing locations that would be hazardous to a human, for example, highly radioactive or toxic industrial environments.
  • Building and grounds security.
  • Obtaining a visual record of activities in situations where it is necessary to maintain proper security or access controls (for example, in a diamond cutting or sorting operation; in banks, casinos, or airports).

6 Essential Features To Look For in CCTV Security Cameras Systems

High-Definition and Wide-Angle Video: Even the most basic cell phone comes with an HD video recording function. The why would you not expect the same from a modern security camera? HD or Hi-def means 1080p resolution. 4K or Ultra-HD (or UHD) cameras are still a bit expensive, but if you are reading this sometime in the future, they may already be commonplace. The footage recorded by HD cameras is crystal clear and distinctive, allowing you and law enforcement officials to detect the smallest details. Additionally, consider wide-angle cameras. These cover a larger area with a single camera, often eliminating the need to install multiple cameras.






Wireless Technology:The clearest pictures are no good if the camera feed can be cut off by snipping a cable. You will want cameras that can transmit the recorded footage wirelessly without degrading its quality. Wireless cameras and related security camera systems also usually come with some form of remote feed and control system. Smaller variants of these cameras can also be installed in cars, providing an additional layer of security to your vehicle.


Night Vision/Low-Light Cameras: You should invest in night-vision cameras or at least those that are capable of recording in low-light conditions. Contrary to what movies would have you believe; these cameras do not produce a green monochrome video. Most cameras record footage that resembles regular black and white videos. The more advanced camera systems use infrared or heat-vision cameras for completely dark areas where simple night vision does not quite cut it. This option, however, is not necessary for every home but is a good option for commercial spaces.


Remote Access and Cloud Backup:Remote access to the recorded video and live feed from your security cameras is crucial. Almost every modern urban home security system comes with companion app what gives you varying degrees of control. This means that you can see live footage from the camera on your cell phone while you are way, even in another city. You may even be able to activate and deactivate the cameras remotely. Besides the ability to monitor your home when you are away, it also gives you control over how and where you can access your security system. They are also usually integrated with other smart home devices, allowing you to dim the lights or turn on your water heater from the same app. Security systems also allow you to store your footage on the cloud, creating backups and archiving footage for later use.


Speakers: Security cameras with speakers may sound pointless but they are a step up from speaking over an intercom or through the door. You can see and talk to a visitor without installing an additional intercom system. There are potentially more uses for such cameras. It can be used to calm and soothe pets when you are away or monitor the outside of your home when you hear some strange noise at night.


Motion Sensors and Automation: Another technology that has been glorified in the movies, motion sensors and motion-activated security camera systems are much more commonplace than most people believe. The primary advantage is that it cuts down the amount of footage being recorded, saving you tones of storage space. It also helps save your internet data as it needs fewer backups to the cloud. More advanced motion detection systems come with movement tracking too. These cameras literally turn and follow a person in their field of view. The motion sensors can also be used to trigger alarms, alerting you to intruders. These are but a few of the essential features of home security camera systems. There are various other features that you can opt for should you need them. Discuss your needs and options with professionals to find the best setup for your home and your family.
