In recent years, Video
Surveillance Systems have evolved from analog-based solutions to IP-based
solutions using IP cameras and a Video Management System (VMS). Whether
deploying entirely new IP-based systems, expanding existing systems with new IP
cameras, or upgrading the VMS software to obtain new functionality, the
compatibility between the IP camera and the VMS has become a critical
component.
IP cameras with megapixel resolution
and advanced capabilities such as analytics, varying and low light level compensation,
motion detection and edge recording require firmware which runs on the cameras.
Such complex functionality in cameras has made it more essential than ever when
deploying IP-based
video surveillance solutions to verify compatibility, and, in many cases,
test in advance of field deployment to ensure that all applicable functions are
working between the firmware of the cameras and the current version of the VMS.
Failure to verify camera-to-VMS
compatibility can have far-reaching and costly consequences. Adverse effects
may include erratic system behavior, limited to no functionality, or, in the
worst case scenario, having to replace recently installed cameras with
compatible versions. Advance testing and verification help avoid both
frustration and expense.
Manufacturers and representatives in
the security industry are striving to arrive at a standard method and protocol
with which the cameras integrate with the VMS. The Open Network
Video Interface Forum (ONVIF) is a leader in this approach. However,
versions of the standard are evolving and the specifics of how manufacturers
adopt or conform to the standard may vary. Adding to the confusion, VMS
providers are tasked with keeping track of the myriad IP cameras available in
the marketplace, as well as with the constant evolution of the cameras’
capabilities, and ultimately, the firmware versions running on the cameras. For
example, a VMS provider may test and, verify a particular camera running a
specified version of firmware only to find that, by the time the camera ships
or is actually deployed, it is running either a newer or older version of
firmware.
With rapid advances in technology
and the manufacturers’ frenzy to keep up, the burden falls on the integrator.
Until a truly universal standard is achieved, it remains the job of the
integrator to test and verify camera-to-VMS
compatibility and to make appropriate upgrades or downgrades to the firmware
version on the cameras or the VMS version. The verification of this
compatibility prior to field deployment ensures a more efficient and effective
system deployment and, ultimately, a satisfied client experience.
