ANALYTICS (from previous

ANALYTICS (from previous page) non-security applications was in the use of sports video analysis to speed through the hours of Formula 1 footage to measure the on-screen presence of advertisers’ logos. This reported on the length of time the logos were shown and how big they were thus painting an overall picture of the effectiveness of the campaign. The company who developed this then moved on to designing the software to allow it to recognise specific faces from a database and then track them in a crowd. Since the unreliable formative years of VCA which saw false alarms being raised by stray dogs, foxes and birds, we now have advanced systems that can tell if a person is walking, running or rolling in an area along with their proximity, behaviour and if they leave anything behind or tamper with the camera itself. So if your client is looking to manage the output from a number of cameras then VCA could be the ideal solution and combining VCA with a top of the range camera can bring additional benefits. There are a few variations on the theme, but the essential method of how video content analysis works is that the camera is linked to a VCA processor that then sends the message to an incident managing system where it is flagged up onscreen as an action. Some cameras have the “intelligence” or the VCA processor built in, while some DVRs contain the processor, however the end result whichever method is used, is that the screen at the monitoring station (or the graphical user interface (GUI) to be more precise) reacts to show that an incident has taken place. Typically VCA is used for recognising loitering, proximity to fences/buildings, suspicious behaviour, abandoned object and reading number plates. If you ask a client about analytics for security and non-security related applications the next time you’re on a job you might open up a whole new area of functionality In terms of licensing, VCA is software and licences generally need to be paid when software is involved. When it comes to edge technology (where the VCA processor is in the camera) this will be included in the price of the unit. If you are using a third party system that offers advanced functionality not available in the camera or if you require a channel to a specific system this would require extra funding. The flexibility of the various options available for achieving video content analysis of footage means that any application can benefit from image processing for security or non-security purposes as long as good quality images are available. Despite how the technology is marketed, many systems are not yet truly ‘plug and play’ although some of the IP technology does fulfil the description - all scenes are unique and cameras need to be individually configured, tested and optimised to meet the task in hand. But once installed and working efficiently, VCA can be hugely beneficial to your customers. If you ask a client about analytics for security and non-security related applications the next time you’re on a job you might open up a whole new area of functionality they had not considered for their cameras, and if you can offer to heavily reduce the number of bodies that are needed to sit looking at video walls to boot, then business could well be forthcoming. 42 www.psimagazine.co.uk

together raising standards Meet the installer Do you use a distributor or buy direct from manufacturers? We use both. We have good relationships with local suppliers and we provide product training to many in Peterborough and the surrounding areas. Is third party accreditation beneficial to your company? Our accreditations and certificates are very important as I know that we would not even be considered without such recognition for a lot of the larger projects that we have. Accreditation proves that we work to high standards and can deliver a high level of service. What would be a typical project for you? We don’t really have a typical project as the work we do can range from the installation of a small domestic intruder system to providing large shopping centres, council buildings or MOJ buildings with a range of security systems and services. Are there any common requests from customers that give you problems? Like many companies we have customers that expect their systems to be installed the very next day! Another problem comes from the widespread availability of information on the Internet. Customers see a price on the Web and expect that to be the cost no matter the specific requirements of the installation. What would make your job easier? A few things spring to mind. Firstly, I would say that there needs to be standardisation in intruder alarm training and secondly, life would be much easier if there were more qualified and experienced engineers in the industry. I also think that we would benefit from clearer tender requirements such as product quantities in the original plan. Do you think there is a skills shortage in the industry? Any trouble recruiting? As already mentioned, there does seem to be a shortage of quality installers around. We have started taking on apprentices to try and bring the new talent on, but when we need a more experienced engineer we have begun using recruitment agencies to try and fill the role. It would be beneficial if there were more training and apprentice schemes specific to the security industry. What is the industry’s biggest myth? That police response isn’t available to everyone Name: Katy Stewart and that it is very expensive. Also I would say that, while it’s not really a myth, a homeowner’s reliance on a bells-only alarm system means the home is not as secure as they may think. They might have had an alarm system fitted, but they are not fully protected without monitored services. Who reacts when they hear an alarm going off? What will be the impact of smart/home automation on the security sector? I think it will open up opportunities for manufacturers to expand product capabilities and for installers to supply a greater range of services. What is your ultimate/fantasy electronic security product? I know for a fact that our engineers would love a device that could be placed onto a panel to instantly tell them the fault! Will England ever win the football World Cup again? I’m afraid that I don’t know when they won it the last time or when it is next being held! If you won £25,000 what would you do with it? I would use it for a family holiday of a lifetime. This month we talk to Katy Stewart from Jensen Security Systems Job title: Company Director Time in security/fire: 9 years Company: Jensen Security Systems Location: Peterborough Areas of expertise: Intruder, fire, CCTV, door access, emergency lighting Accreditations: NSI Gold for the design, maintenance, installation and commissioning of intruder alarms, CCTV systems, door access systems and fire alarm systems. Engineers are BAFE qualified for fire extinguisher maintenance and the NICEIC domestic and commercial certificates allow the undertaking of all electrical works. “I know for a fact that our engineers would love a device that could be placed onto a panel to instantly tell them the fault!” www.psimagazine.co.uk 43
