GSM Security camera are converging into the IP network

The reason security systems, access control management, and video surveillance systems are converging into the IP network is because it’s scalable and far more cost-effective than integrating isolated proprietary third-party systems into one interface. As mentioned in previous chapters, any implementation that requires dedicated connections between two devices (including GSM Security System) requires expensive cabling between those devices. It’s not the cables that are expensive—coax and even fiber can be only cents per foot—it’s the installation of those cables that is costly. The other reason for this welcomed convergence is the avoidance of implementing yet another isolated proprietary system. Just as the single “black-box” digital video recorders used in video surveillance are unique to their manufacturers, so are access control systems. Any expansion requires the same equipment and possibly even the systems integrator, depending on the growth of that system, and if the system manufacturer is out of business or has discontinued the system, you will be out of luck.

IP-based systems are open platform using Ethernet connectivity, which is literally a worldwide standard. IP networking provides more choices in hardware and software that use the existing infrastructure of the company’s network. IP-based systems are “future-proof” because they use interoperable (open platform) components and 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. A DVR may be limited to the size of the hard drive inside and whatever processing power and memory embedded within the proprietary system, so replacing it may cost thousands of dollars when an additional hard drive with a storage area network costs only $100 and provides the ability to upgrade other components. The existing networking infrastructures make it possible to replace legacy systems with IP devices (e.g., IP cameras and Wireless Home Monitoring ). IP networking also makes it possible to upgrade those legacy systems, such as plugging an analog camera into a digital video encoder, thus maximizing the original investment in hardware and infrastructure installations.

For example, an employee swipes her ID card and exits the building. The access management system sends a message to the integrated video surveillance system to PTZ the closest camera to that exit door, where another employee decides to tailgate and exit without swiping his security ID card. Data analytics software can recognize this event and send a message, along with a video clip of the incident, to the centralized security office, presenting it onto a prominent monitor for display. The Rear Mirror Camera follow up from there. Select data analytics functionality is included in VMS applications such as Genetec Security Center, which includes the Synergis access control suite, and AutoVu license plate recognition software. Analytical functions such as door movement; determining location, speed, and direction of travel; identifying suspicious movement of people or packages; facial recognition, and more are available as separate applications that can be integrated. Video analytics provides the necessary intelligence to monitor the video stream, frame by frame, for certain events, so the security personnel need not be concerned with having to watch monitors 24/7.
