PSIA Vs. Onvif
Author : Zainab Al Qaisi
While IP allows for a degree of open interconnection, a standard interface between cameras and video management software is needed to achieve true plug-and-play among devices, and eliminate the need for software development kits customized for each brand. Both groups have demonstrated cameras -to-VMS interoperability. The race is on to develop the next series of specs, which aims at standardizing interoperability across the enterprise security ecosystem.
The acronym “ONVIF” stands for the “Open Network Video Interface Forum” and it’s an open industry which is committed to accelerate the adoption of network video in the security market through a global open interface standard. It was founded on November 25, 2008 by Axis Communications, Bosch Security Systems and Sony.
The goal of the ONVIF forum is to facilitate the development and use of a global open standard for the interface of network video products. The ONVIF specification will ensure interoperability between network video products regardless the manufacturer. It will become even easier for end users, integrators, consultants and manufacturers to take advantage of the possibilities offered by network video, resulting in more cost-effective and flexible solutions, expanded market opportunities and reduced risk.
The acronym “PSIA” stands for “ The Physical Security Interoperability Alliance “ and it’s is a global consortium of over 65 physical security manufacturers and systems integrators that focused on promoting interoperability of IP-enabled security devices across all segments of the security industry. Participating companies include the following: Arecont Vision, Assa Abloy, Cisco Systems, GE Security, Genetec, Honeywell, IBM, IQinVision, Johnson Controls, Kastle, March Networks, Milestone Systems, NICE Systems, ObjectVideo, OnSSI, Pelco, SCCG, Stanley Security, Texas Instruments, Tyco International, Verint and Vidsys.
PSIA’s objective is to develop standards, which are relevant to networked physical security technology. Under the direction of its Board of Directors, PSIA promotes and develops these standards across all segments including video, access control, analytics and software.
But what is the reason behind both PSIA and ONVIF?
Growth of opportunities in the surveillance market has driven the demand for open standards of interoperability. With companies ;realizing that delivering network camera standards is more important for expanding and maturing the IP video surveillance market, the formation of the two bodies — the Open Network Video Interface Forum (ONVIF) and the Physical Security Interoperability Alliance (PSIA)had to be found
ONVIF Strengths
• As the global IP camera leader and de facto leader of ONVIF, Axis commands significant respect amongst manufacturers and integrators.
• ONVIF seems to be favored in Europe and Asia.
PSIA Strengths
• PSIA is moving faster than ONVIF is.
• PSIA has opened up sooner than ONVIF.
• PSIA specification is easier to implement.
Standards like ONVIF and PSIA will mainly cover basic functionality for IP cameras early on this means that it will be easier to bring an IP camera with the basic functionality to the manufacturers market of security. Customers and users expect to see a high number of camera manufacturers , who have not previously produced IP cameras to enter this field of ONVIF/PSIA standards and that the effect of these entrants will be t low-end, and IP cameras will be and commoditized, thus improving the ROI for IP deployments. The effect of this may be very well that the conversion from analog to IP will speed up again already in 2010."
When do we adopt ONVIF? And when do we adopt PSIA?
Companies can adopt the ONVIF standards for high-end video devices with Camera analytics and configurations.
Companies that need to control devices for PTZ, along with other services like storage and PSIM, can adopt PSIA, since the PSIA standard is based on REST, it is more appropriate for other areas of the physical security industry.
• Main differences between both Standards:
1. ONVIF: Lead by Axis, Bosch and Sony, they seem motivated to protect the interests of the largest selling camera manufactures.
PSIA: Lead by Cisco and supported by a half dozen camera manufacturers, they seem motivated to protect the interests of manufacturers with lower IP camera market share
2. PSIA provides an easy interface for analytics integration compared to rigid ONVIF specifications.
3. Due to its REST-based architecture, PSIA's implementation is light-weight compared to ONVIF's SOAP-based architecture implementation.
4. PSIA has already defined specifications for media recording and storage, while ONVIF is yet to define specifications for storage. This may be included in its future specification versions.
5. Since PSIA specifications focuses on broader aspects of physical security, PSIA also provides specifications for physical security information management (PSIM) integration.
The adoption of IP camera standards is recognized to be a significant factor for the continued growth of IP video in the security industry because it reduces s the complexity and cost of IP surveillance installations. With the availability of ONVIF and PSIA standards, the basic levels of integration required between hardware and software should make it easier to implement IP video. Hardware manufacturers, software providers and installers are able then to focus on other products’ developments and services that can add more value for customers.
Common network camera standardization will speed up integration efforts and compatibility between components from multiple vendors. This will reduce the overall cost of surveillance solutions.
