Video surveillance is one of the most obvious security measures we see on a daily basis. Security cameras are installed on nearly every wall of every building, indoors and outdoors. However, camera usefulness can vary widely. Legacy video systems were designed for evidence collection after an incident. Modern systems are meant to do much more.
Basic Components and Functionality
Modern security cameras can do much more than just record video. New cameras are connected to the IT network and, in many cases, have multiple processors that perform video analytics and other tasks. The cameras are usually powered by an ethernet cable. It’s the same cable found in residences that connect the internet to a computer.
IP security cameras come in a variety of designs. There are large cameras that may be fixed on a specific direction and positional cameras within domes, known as PTZ or pan-tilt-zoom cameras, that can be controlled and moved by security or management. There are cameras designed to operate in broad daylight, and many, in very low light conditions. There are even cameras that look at the thermal signatures of landscape, vehicles, and humans to determine activity in critical areas.
Video analytics within the cameras or on external computers can evaluate the video and create custom alerts that are triggered by specific behaviors or conditions. Automatic alerts are helpful when the number of cameras in the system increases and can no longer be reliably viewed in real-time. They can also serve as back-up detection for a security team in smaller fleets of cameras.
Cameras send their data across the network to one of two general types of control systems: cloud-based or server-based video management systems. Cloud-based systems send the video data across the internet to be processed and stored on managed devices at a secure data center. Cloud-based systems reduce the hardware and maintenance costs associated with a video surveillance solution. Server-based solutions can receive camera feeds across the organization’s local or wide area network. This type of solution may be deployed where internet connectivity is limited, or on-premise video data storage is preferred.
Computer workstations, and in many cases mobile devices, are deployed on location for camera viewing and control. They can be equipped with video management software or apps that communicate with the local servers or, in cloud-based solutions, can be connected via a web browser interface across the internet
Integrated Systems Create a Solution
Unified electronic security systems include video surveillance, intrusion detection, access and door control, and a public-address system to deliver clear messages. Integrated solutions streamline normal and emergency operations by decreasing investigative and response times.
The Right Partner
The right security solution design results from years of training and experience.
Netronix begins the solution design process by evaluating an organization’s unique application and performance expectations. Input is gathered from the security team, facilities staff, IT department, administrators, local law enforcement, and other stakeholders. Next, we perform a site survey to evaluate the physical layout of the facility and uncover potential vulnerabilities. Once the risks and expectations are clearly outlined, our team designs a unified security solution. Products from a variety of leading manufacturers are assembled into a custom design. Demonstrations of key components, from cameras to the graphical user interface of one or more software platforms, are performed with the client. Every specialized process is rooted in our ongoing industry and technology training.
