(St. Louis, Missouri) 09, July, 2009 – Kondor Security is proud to announce that we are an Authorized Reseller of the ISONAS PowerNet PoE/IP Reader-Controllers.™
Security system designers, facility managers and building owners have all been dreaming of the day when a single cable can replace the multitude of cables currently needed for card reader communications, request to exit, door position, and lock power.
One of the biggest advantages offered by an ISONAS PoE infrastructure is the inherent ability to facilitate system wide power back-up. If your system is PoE based, then backing up power for the entire system is simplified. Employing an emergency generator or a network UPS will ensure that the access control system continues to be fully functional during a power outage. Legacy systems typically employ battery back-up techniques that fail to provide sufficient power for critical components such as door locks or request to exit devices.
An important concept to recognize when considering the deployment of a PoE network is that of power sharing. This concept has largely been ignored by PoE marketers. Simply stated, power sharing is when the total power available from power sourcing equipment is shared across all of the available ports. So if the power sourcing equipment delivers 12.95W of power and 9 or 10 watts are required on each port, your equipment will only power one port. The slight of hand that the industry marketing fails to acknowledge is that yes, while you can power your access control system with older IEEE P802.3af power sourcing equipment, they don't tell you that you'll need a switch for every access control door in the system. This is not an economically feasible solution. Not every pre-IEEE P802.3at switch employs the power sharing principle, but it is something that any potential PoE system user needs to be wary of.
Today's newer switches do not utilize this methodology. Each port can be configured by the operator to deliver a specific class of power. This ensures that your purchase of an 8 port switch will enable you to power the devices required at eight different doors if needed.
PoE is quickly becoming a viable alternative for access control system designs. Network switch manufacturers are producing power sourcing equipment designed specifically for the security industry and access control manufacturers offer PoE capable powered devices for their access control systems.
