4 tips to successfully deploy a wireless security network
Wireless technology can improve the performance of an organization's physical security system while lowering the cost and complexity of deploying cables connecting security cameras and access control systems throughout a facility.
Here are four tips to help enterprises successful deploy wireless security network from Matt Nelson, CEO and president of AvaLAN Wireless Systems, published in SecurityInfoWatch.
First, you need to analyze the wireless environment to understand how many Wi-Fi access points and devices are in the same area of deployment as your security system. "Remember that every laptop, phone and headset will be fighting for use of the RF spectrum in any given area," Nelson advises.
One approach to lessen interference is to use frequencies other than those being used by these devices, which is often the 2.4 GHz band. Consider using the 900 MHz and 5.8 GHz bands for the security system connections.
Second, you should decide between line of sight (LOS) and non-LOS. While LOS is the best for wireless performance, it is not always possible. RF signals using frequencies below 1 GHz can go through walls and objects better than those using frequencies above 1 GHz. Also, narrow bandwidth signals and higher RF power signals go through walls and objects better than wider bandwidth and lower power signals, Nelson explains.
Third, you need to determine whether using a mesh network is the best approach. While a mesh network can seem attractive, actual performance can vary. Nelson recommends point-to-point and point-to-multipoint wireless Ethernet installations instead because they are "more predictable, reliable and cost-effective."
And fourth, you should keep in mind the need for electrical power sources for cameras and access control systems. Power sources include solar, wind and batteries. "Make sure your wireless networking configuration has a power plan," Nelson stresses.
