These are the primary components of a CCTV system. They capture video footage of the monitored area and transmit it to a recording device or a monitoring station. CCTV cameras come in different types, such as dome cameras, bullet cameras, PTZ (Pan-Tilt-Zoom) cameras, and more. They can be analog or IP-based, with IP cameras offering higher resolution and advanced features.

The VMS is software that allows users to manage and control CCTV cameras. It provides features like live viewing, video recording, playback, and camera configuration. The VMS enables operators to monitor multiple cameras simultaneously, set up motion detection, and receive alerts in case of suspicious activities.

CCTV systems use recording devices to store video footage for later analysis or evidence. Traditional systems use Digital Video Recorders (DVRs), while modern systems often utilize Network Video Recorders (NVRs) that can handle IP cameras. These devices come with various storage capacities and can be customized based on the requirements of the security system.

This is a centralized location where security personnel or operators monitor live feeds from CCTV cameras. It may include multiple video screens, alarm systems, and advanced software for situational awareness and incident response. The control centre is responsible for real-time monitoring, detecting security breaches, and initiating appropriate actions.

In conjunction with CCTV, access control systems help regulate and restrict entry to secure areas. These systems include keycards, biometric scanners, and PIN codes to authenticate individuals. Access control systems can integrate with CCTV, allowing video verification of access events and enhancing security measures.

Alarm systems are an integral part of security infrastructure. They can include intrusion detection sensors, fire alarms, and other sensors that trigger alerts in the event of unauthorized access, fire, or other emergencies. When an alarm is triggered, CCTV cameras can be configured to focus on the corresponding area to provide visual verification.

To secure the external boundaries of a property, perimeter protection systems are used. These systems often incorporate technologies like CCTV cameras, motion sensors, infrared detectors, and fences with intrusion detection capabilities. They help deter intruders and provide early warnings for potential security breaches.

Modern security infrastructure emphasizes integration and analytics capabilities. CCTV systems can be integrated with other security systems like access control, alarm systems, and video analytics software. Video analytics leverage AI technologies to automatically detect suspicious behaviours, identify objects, track individuals, and generate actionable insights from the CCTV footage.

As security infrastructure becomes more interconnected, cybersecurity is of paramount importance. It is crucial to implement robust cybersecurity measures to protect CCTV systems from unauthorized access, hacking attempts, or data breaches. This includes using strong passwords, regular software updates, network segmentation, encryption, and implementing best practices to ensure the integrity and confidentiality of the video feeds.
