Using wireless communications in security applications

March 5, 2019

The Senstar Wireless Gate Sensor (left) and the Senstar LM100 (right) are examples of field-proven wireless security products.

When tasked with selecting equipment to protect a site, security professionals typically choose the technologies with which they have familiarity and confidence. This makes perfect sense – no one wants to risk using unproven technology when security is on the line. That being said, new technologies shouldn’t be discounted, especially if they meet performance requirements and offer distinct benefits.

A good example of this is security devices that use wireless communication. Many traditionally hard-wired devices are now available in wireless versions, including network cameras, access control devices and intrusion detection sensors. Going wireless dramatically simplifies installation and lowers costs, as technicians no longer need to physically run copper or fiber cable to each device. Some devices may also be battery or solar-powered, leading to further savings.

However, questions remain about reliability, and the vulnerability to hacking of these new devices, especially given people’s experiences with consumer-focused technologies like WiFi or Bluetooth. For security professionals, the key is understanding that not all wireless technology is the same and that there are solutions designed specifically for security applications.

This article discusses how, when designed right, wireless links are reliable and secure.
