S10 ACCESS CONTROL Trends And Technology | JULY/AUGUST 2019 boards that enable and control these and other devices. It’s in this current environment that PACS now operate—with functions that are core to risk management and mitigation and focusing on interoperability—using open platforms as a building block to ongoing integration. A single, unified vision for access control will be the next logical continuum in the move to smart cities, spaces and buildings, fostered by standards, common interface protocols and open systems. ONVIF is an organization whose mission is to facilitate the standardization of interfaces that enable interoperability between IP-based physical security products. Application and extension of the ONVIF open platform is the next step in the future of loT functionality as it continues to move in the direction of incorporating ancillary devices, peripherals and exterior technologies from different manufacturers. The overall mission of ONVIF is to establish a common communication interface for all security devices and clients, across security disciplines, systems and vendors. Standardized interfaces promote and encourage effective interoperability, regardless of brand and with openness to all companies and organizations. ONVIF profiles and conformant products can support one or more of the following Profiles: Profile A for broad access control configuration (credentialing, management); Profile C for basic access control; Profile G for edge storage and retrieval; Profile Q for quick installation; Profile S for streaming video; and Profile T for advanced video streaming. Currently, ONVIF access control Profile C and Profile A cover an access control unit (ACU) device and an access control management client and allow for the mixing and matching of access control devices and clients within a system. Newer technologies on the periphery require interfaces between these new devices and the ACU or the access control management software, which are not yet covered by existing profiles A, C and S. The orchestrated and purposeful migration to a new body of work is the cornerstone of the continuing development of IP and network-based systems. This next point of study in PACS from ONVIF would enable additional types of products, such as surveillance cameras, gate controllers and other input systems to do credential identification and interact with various types of management systems from different manufacturers—further driving the adoption of ONVIF interfaces in the PACs and video surveillance space. The new directive will also increase the potential contracting use cases for systems integrators and end-user customers in physical access control through broader solution sets available from manufacturers. Biometrics/License Plate Recognition In the example of facial recognition (Figure 1), the example shows an existing video camera with facial recognition capability and a relay output port. The use case is a scenario where an entrance door to a building has a camera that can read facial biometric data and sends the data to a client, possibly unlocking the door if instructed by the client to do so. With the new profile interface, the camera is capable of relaying biometric data to the client where it is authorized. The client then sends back a signal that access is granted or denied. In the example of license plate recognition technology (LPR) (Figure 2), the LPR subsystem usually includes an auxiliary gate, ground coil and LED display device. The LPR machine is equivalent to the license plate reader. Through the optical character recognition (OCR) function, the vehicle license, brand, color and other attributes are automatically output. As with the facial recognition example, the interface between the devices and the client does not specifically control the decision. The device simply passes credential information (e.g., card number, license plate number, biometric data, etc.) to a client that can make the access decision. The interface takes the intelligence from the external device and allows communication of the specific access control device into the system. In the future, it may also be possible for combinations of information, data and decision making from a wide range of devices, not just access control and video. The widespread and cascading benefits of the ability to integrate new ancillary systems, peripheral devices and remote technologies can have significant impacts throughout the entire security industry. For users, open devices provide the flexibility to specify optimal products for specific needs without being locked into a certain vendor. Users can integrate control panels and management software from different manufacturers, rather than remain pigeon-holed to a technology or solution. In addition, open systems promote lower total cost of ownership and future proofing, with nearly unlimited choices of hardware and software. An ONVIF conformant video management software, for instance, will allow users to integrate ONVIF conformant devices from different hardware manufacturers. With software that supports both ONVIF and proprietary application programming interfaces (APIs), users can choose to use the ONVIF interfaces for certain functionalities and the proprietary API for other features at the same time. Having ONVIF conformant products is like having an insurance policy that protects the end-user’s technology investment. For systems integrators and specifiers, ONVIF conformant products New cybersecurity processes are becoming embedded in security, surveillance and automated processes —from product conception to final commissioning.
