April 2019 / / Security Business 15 really adopt Wi-Fi because they have unique challenges,” Chapman explains. “Campuses usually have many buildings, thousands of doors, and large user populations. Many buildings are old structures built in mortar and concrete – where deploying traditional access control at an existing opening was cost prohibitive. Wi-Fi technology enabled those campuses to secure more openings for a better price point, so they quickly adopted and embraced the technology and its value.” In my own projects I have noticed a shift towards wireless in commercial projects, particularly with clients interested in making an effort to future-proof office environments for floor plan reconfigurations down the road. The Downside As with any technology, there are some drawbacks. First, some wireless solutions – Wi-Fi in particular – require you to give up immediate communication between the access head-end and the lock. Those locks are not in continuous communication with the head-end, rather they poll on a regular basis for updates. This would introduce a delay when sending updated access control lists or lock/unlock commands. Some proprietary wireless versions, including ASSA ABLOY Aperio, avoid this through more continuous communication. A second drawback is that wireless locks depend on batteries – an important ongoing maintenance routine for end-users or service providers. For this reason, mission-critical doors or entry doors that get used several hundreds of times per day are justified for sticking with wire. “We still believe when it comes to perimeter access control, it is best applied as a hard-powered reader/panel ‘traditional wired’ type of a solution,” Chapman says. Finally, wireless requires certain door hardware types to function, which may deviate from an end-user’s defined organizational standards. For more information on wireless, I recommend reaching out directly to the manufacturers to understand their particular product offerings and how they might fit into your customer’s hardware standards. An easy way to reach your preferred vendor is to search for each company and/or particular product lines and request more information in the SecurityInfoWatch buyer’s guide at ■ » Brian Coulombe is Principal and Director of Operations at DVS, a division of Ross & Baruzzini.
