Key Ways how RF Detection can Ensure Improved Safety, Health, and Security

RF sensors and software specifically designed to locate cell phones, smart watches, laptops, and other RF-emitting devices such as visitor badges and asset tags can be used to detect and position the devices.

Fremont, CA: Users can see the unseen with radio frequency (RF) detection solutions. A wireless device positioning system can, for instance, bring visibility into the location of devices, people, and assets within a building, providing indoor intelligence that can not only increase security but also offer valuable benefits to help agencies achieve their health and safety objectives.

Indoor intelligence technologies encompass a diverse set of interconnected systems that make buildings smarter and provide valuable insights that can be used to address operational and security requirements. It all begins with knowing where people and assets are and putting them on a detailed, dynamic digital map of the agency's facilities. RF sensors and software specifically designed to locate cell phones, smart watches, laptops, and other RF-emitting devices such as visitor badges and asset tags can be used to detect and position the devices. The possibilities are nearly limitless from there, as services and specific applications can be layered on top.

Here are two of the most popular security-related applications for indoor intelligence:  

Response: When an incident occurs, the indoor intelligence provided by RF detection solutions can assist agencies in communicating relevant information to security personnel, first responders, and others who are in need. It can provide answers to questions about the location and movement of employees and visitors, as well as whether everyone has exited the building.

Investigation: RF detection can be used as a forensic tool to aid in the investigation of a variety of incidents, ranging from wireless intrusion to assault. To review what wireless devices were in a specific area at a given time, security operators can use a DVR-like playback function. Another extremely effective application combines RF detection with security video. This sensor fusion correlates the presence of RF devices to individual security video frames, allowing security departments to address some of the difficult and persistent challenges associated with traditional video surveillance. This RF-enabled video analytics solution, for instance, can assist in identifying suspects even if their faces are obscured, they are in low- or no-light conditions, or they roam the building where cameras are not present. It also enables officials to search large video archives as well as quickly jump to relevant frames in recorded video, tracking people of interest across cameras and even off-camera to gather evidence. Security teams can also create a watch list of potential bad actors and be notified if they return to the agency's premises.
