The Difference Between VMS & PSIM and How Both Can Boost Campus Security

Confused about whether you should adopt a video management system or physical security information management system? Here's how you can determine what you need.

Both physical security information management systems and video management systems can be perfect solutions for today's security systems operators.

It is not a new debate. A good deal has been reported on whether projects are better served with a physical security information management (PSIM) system or by leveraging the integration capabilities available with a video management system (VMS). The answer, of course, is both are excellent solutions that can help make sense of the multiple streams of data bombarding security system operators in today’s physical security environment.

The choice between the two approaches hinges on the needs of the users and variety and types of systems requiring integration. Though both the PSIM and the VMS offer their own sets of benefits, there are some definitive differences between each system and philosophical approach.

Some of these differences are obvious, while others are more nuanced and perhaps not apparent until you’re in the thick of things using the system in a real-world setting.

A VMS Prologue
VMS solutions have become increasingly sophisticated and capable of integrating multiple types of physical security information and environmental systems into a cohesive and understandable interface, providing a broad view of an environment’s physical security. These systems are most commonly used with surveillance-related applications such as access control, license plate recognition (LPR) and video analytics.

As a central point (or anchor) of system integrations, a VMS is often applied in active surveillance environments where the security requirements demand full-time video use. In this capacity, a VMS typically treats other integrated systems as playing a supporting role, augmenting the VMS’s existing view of a facility. Data from these other systems is incorporated into the VMS through the lens of the video surveillance system.

Integrated Vs. Unified VMSs
Historically, a VMS stood as an anchor platform through which other systems integrated via an application programming interface (API). In these cases, licensing must be maintained for each of the different vendors’ systems in addition to maintenance and updates for each.

The video or anchor interface only enabled basic interaction between the integrated systems. This allowed an operator to gain some level of situational awareness, i.e. video related to an alarm. However, if an operator needed to investigate further, they had to exit the VMS and use another interface to attain the details necessary for a holistic understanding of an event.
