Assesment: Is VMS an Essential System Element?

When considering bespoke smart systems, the arguments for switching from hardware-based video management to VMS solutions are convincing. This is highlighted by the fact the majority of manufacturers now offer some form of VMS, and the market share of the leading providers continues to grow. Increasingly, forward-thinking integrators are embracing all that VMS offers. What does VMS software offer to smart solutions?

VMS systems are the solution of choice for forward-thinking integrators, and for a very good reason. The solutions offer a flexible and credible platform which allows the creation of smart, value-added and bespoke systems which meet end users’ needs. They offer a high level of security which can be adapted to address any risk level, and can also add benefits that go beyond security. As a result, the systems offer a genuine and quantifiable return on investment for the customer.

The question some might ask is why, if VMS is so powerful, do NVRs still appear to be so prolific in he industry? The answer is simple: they offer a low cost system for those who are looking for a basic system which records video and offers entry-level functionality.

There are end users who require such systems. Some do so because their integrator hasn’t offered them a smart option and as a result they believe restricted hardware is their only choice. Others are focused solely on the capital cost rather than total cost of ownership and return on investment.

However, as more business and organisations embrace the added value of smart solutions and IoT technology, the arguments for using a VMS become ever stronger, to the point where not specifying one seems almost blinkered.

It should be noted that VMS solutions are not expensive, not complicated to install or use, and are not limited to sites with large camera counts. The vast majority of providers offer solutions which are very cost-effective (and at times free of charge) for small sites. The size of the customer’s business, the number of devices being used and the budget are not barriers to using a VMS over an NVR.

It is important to also realise that VMS solutions are not just for video! The VMS – video management system – tag is slightly misleading, as today’s leading solutions are far more than video management systems.

The leading VMS packages support connection with cameras, video codecs, recording devices, access control, intruder alarm systems (and standalone detectors and sensors of various types), perimeter protection systems, fire detection, safety and building management systems. Specialised areas such as traffic incident detection, business intelligence, asset tracking and process control can also be added by integrators with no need to write code or carry out complex programming.

Increasingly, VMS software also integrates with a host of IoT devices which are ideal for smart solutions. These include – but are not limited to – lighting, audio broadcast, communications, environmental monitoring, digital signage and displays, elevator control, HVAC management, power and energy management, real-time status reporting, vehicle tracking, etc..

The functionality available from a typical VMS goes above and beyond that offered by hardware-based video systems. Because the VMS is effectively software ‘under the bonnet’, this means it is inherently more flexible. Creating a bespoke solution which might be complicated or impossible with a hardware-based system can be achieved with ease via a VMS, often using little more than drop-down menus and simple selection buttons.

VMS solutions do all the things an NVR can do: record, play and display video. That much is expected. However, the software can also offer advanced management of video, whether that be sharing it across a business or organisation, tracking events and incidents, delivering data that makes the business operations more efficient or integrating it with other systems and technologies.

The right choice?

When specifying a VMS, integrators face a growing number of options. VMS systems are provided as software-only or appliance-based on-premise solutions, cloud-based systems and hybrid versions incorporating local and remote elements. Additionally, there are open platform options as well as VMS packages which are limited in terms of support for third party devices.

Pinning down which route to consider is a relatively simple task, if you consider the pros and cons of each approach.
Starting with open platform systems, these will support a wide range of third party devices, usually covering all professional quality manufacturers and devices. The positive of an open platform system is that legacy cameras and other devices will be supported (unless the site has been fitted with obscure, non-branded devices, in which case the best approach will always be to replace with credible devices).

Additionally, because many open platform VMS providers don’t manufacture cameras, companies which do are willing to work with them, often in advance, on forthcoming products. This means that when a manufacturer launches a new camera or range of products, the VMS provider will have already written a driver. This allows support from the day the new products are launched.

The downside of many open platform systems is that every device will require a license. However, given the flexibility of the systems, coupled with the certainty that devices will be compatible, makes this small cost one worth bearing.

VMS packages which are not open platform are usually offered by manufacturers who also provide hardware components such as cameras and NVRs. As such, the main goal of the VMS is to supplement their hardware offerings. Typically, such systems will be optimised for use with the manufacturer’s devices, and as such can represent a ‘one brand’ option. Some might claim to support third party devices, but this will often be a few selected partners, or basic operational functionality via ONVIF compliance.

A number of single brand VMS packages will not charge license fees if the manufacturer’s own devices are used, but will for third party cameras. It is important to find out whether a license fee gets a driver for all functionality or if the connection will be limited to basic features.

If a site has a large number of legacy cameras all of a single brand, then there is a case to consider the use of a VMS which is not open platform. There will be some cost savings on license fees for devices added, and functionality with the provider’s own hardware could be optimised to allow simpler use of certain proprietary functions.

The downside comes in terms of expansions and upgrades. For example, if the VMS and cameras are provided by Manufacturer A, but Manufacturer B brings out a device with advanced features which the user needs, will the new device be compatible? If the new features fall outside of basic video functionality, they may not be available using an ONVIF connection, so a driver will be needed.

If Manufacturer B is a competitor of Manufacturer A rather than a trusted partner, the odds are there will be little pre-launch cooperation. Indeed, it may well be the case that if Manufacturer A is working on a similar product, they’d have little desire to support Manufacturer B’s device, at least not until theirs was available. This can cause problems, especially in the customer is putting pressure on to have the new device added to their system.

There will be cases where a limited VMS makes sense, and some are priced very competitively because the goal is to sell more hardware! However, if the aim is to create a bespoke smart solution which allows flexibility in terms of expansions and scalability, it is hard to look beyond an open platform system.

The next choice is whether a software or appliance-based option is required. Many VMS providers will offer an appliance, which is essentially a server pre-loaded with their software. Appliances are usually made, under license, by the IT industry server manufacturers, and so you are purchasing an appropriate IT-centric device.

Appliances do take away the headache of specifying the right hardware for a system, as VMS providers will indicate how many devices the appliance will support, and which features and functions can be used concurrently. However, where a business or organisation has legacy hardware, or where very specific infrastructure needs must be met, working with a customer’s IT team is the best approach. In reality, often the user’s needs will dictate which approach is best.

A recent change in the world of VMS has been the addition of cloud services. These allow typical VMS functionality such as recording, archiving, viewing and video management to be carried out on a local level, while additional services such as business intelligence reporting, cybersecurity checking, remote connectivity and advanced analytics to be carried out via a cloud service.

Many of the cloud-based options add value to the system, and so can either be included at initial installation or added afterwards as and when the customer requires them.

Increasingly, VMS providers will have trusted partners who they work with that offer loud services. This means you can be assured the services have been tested with the VMS, and there will be adequate support information to ensure the infrastructure will support the services being offered.

As with considerations about whether to specify software-only or appliance-based VMS, the decision about cloud services will come down to the requirements of the customer. However, it is worth considering communications for cloud connectivity, because some of the more exciting and beneficial developments coming onto the market in the near future will be based on cloud services.

Demand from end users for these cloud services will grow, so consider this when specifying a VMS.
