  Closed-circuit television (CCTV) systems are one of the most traditional forms of video security systems. These systems include cameras that transmit recorded video to a specific set of monitors or recording devices via cables. CCTV systems help monitor sensitive areas in business environments such as banks, retail outlets, and corporate offices.

• Analog Systems

  These systems capture video footage using traditional cameras with an analogue signal. While these systems are less complex and cheaper to install, their video resolution cannot match newer technologies. Many businesses have used them for basic security monitoring.

• IP Camera Systems

  IP (Internet Protocol) systems utilize Internet protocol to capture and transmit security video. Unlike or analogue systems, these cameras capture and send digital video footage that can be accessed in real time via the web. IP systems have other enhancements, like resolution, flexibility, and the ability to integrate with other security systems.

• Wireless Security Systems

  Wireless security systems do not use cables to connect cameras and other system components. They use radio signals to communicate. Because of their flexibility and ease of installation, wireless systems are often recommended for environments where installing wired systems is difficult. These are frequently used in offices under lease, construction sites, or any other area with a fluctuating layout.

• Cloud-Based Video Surveillance

  In this case, instead of local video storage, the recorded video is uploaded to the cloud. This allows users to access video footage using any device connected to the Internet. Cloud-based systems are valued for their ability to back up data to prevent tampering or destruction by malicious agents.

• PTZ Systems

  Short for pan-tilt-zoom, these systems allow operators to remotely control cameras to move or zoom in on a particular area of concern. These systems are advantageous for covering wide areas such as parking lots, shopping malls, event venues, and other expansive spaces.

• IP PTZ Cameras

  These integrate the features of PTZ with Internet protocol technology. They provide the same remote control functionality with enhanced image quality and camera system flexibility. These PTZ cameras can be monitored and controlled over the Internet.
