Many of the VMS software packages, including those bundled with the less expensive DVR card solutions, offer a way to integrate or add messages, alerts or alarms to select events such as motion detection, tampering or even access control.
The more complete VMS suites like Genetec Omnicast, Milestone, OnSSI or ipConfigure have richer integration possibilities provided by the addition of a Software Development Kit (SDK). The SDK provides an application programming interface (API), scripts, code, and/or a development or configuration interface between your core software solution and third-party applications.
The more demands are placed on the VMS, the more sophisticated the integration, unless you choose a VMS software that can provide these functions or appears capable of integrating with select third-party applications.
The reason why security systems, access control management and video surveillance systems are converging onto the IP network is that it is scalable and far more cost-effective. As mentioned in the previous chapters, any implementation that requires dedicated connections between two devices (including CCTV) requires expensive cabling. It’s not the cables that are expensive – coax and even fiber can cost pennies per foot – it’s the installation of those cables that is costly. The other reason for this welcome convergence is the implementation of yet another proprietary system. Just as the black box digital video recorders used in CCTV are unique to their manufacturers, so are access control systems. Each expansion requires the same equipment and possibly even the system integrator as the system grows. If the system manufacturer is out of business or has discontinued the system, you’re out of luck, so the convergence of all security systems to existing standards is a welcome change in technology, implementation, and business process improvement.
IP-based systems are open platforms that use Ethernet connectivity, which is literally a worldwide standard. IP networks offer a wider choice of hardware and software that leverage the existing corporate network infrastructure. IP-based systems are future-proof as they use interoperable (open platform) components that make it easier to take advantage of new advances in IP cameras and digital video encoders, access control systems, security systems and general computing growth. As mentioned in
DVR may be limited by internal hard drive size and proprietary system processing power and storage; Therefore, when an additional hard drive with a storage area network (SAN) costs only $100 and offers the opportunity to upgrade other components, the replacement can cost thousands of dollars.
The existing network infrastructures make it possible to replace legacy systems with IP devices (e.g. IP cameras and biometrics). IP networking also makes it possible to upgrade these legacy systems, such as B. Connecting an analog camera to a digital video encoder, maximizing the initial investment in hardware and infrastructure installations.
Video analytics can also be used throughout the integrated security system. For example, an employee swipes their ID card and leaves the building. The access management system sends a message to the integrated video surveillance system to pan, tilt and zoom (PTZ) the camera closest to that exit door if another employee decides to go behind the door and exit without their security pass to pull. Video analytics software detects this event and sends a message, along with a video clip of the incident, to the central security office, which displays it on a high-visibility monitor. Security forces follow from there. Video analytics applications include door movement; determination of location, speed and direction of travel; Identification of suspicious movement of people or packages; License plate identification and facial recognition and more as the technology expands.
Video analytics provide the intelligence needed to monitor specific events, eliminating the need for security personnel to monitor monitors 24/7.
