RF sensors and software specially designed to locate cell phones, smart watches, laptops, and other RF-emitting devices like visitor badges and asset tags can be employed to detect and position the devices
Fremont, CA: Users can see the hidden radio frequency (RF) spotting solutions. A wireless device placement system can, for example, bring visibility into the location of devices, people, and assets within a building, offering indoor intelligence that can increase security and offer valuable advantages to help agencies attain their health and safety objectives.
Indoor intelligence technologies encircle 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 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 explicitly designed to locate cell phones, smart watches, laptops, and other RF-emitting devices like visitor badges and asset tags can be used to detect and position the devices. The possibilities are nearly limitless, as services and specific applications can be layered on top.
Here are two of the most famous security-related applications for indoor intelligence:
Response: When an incident happens, the indoor intelligence offered by RF detection solutions can help agencies communicate appropriate information to security personnel, first responders, and others in need. It can answer questions about the location and movement of employees and visitors and whether everyone has exited the building.
Investigation: RF detection can be employed as a forensic tool to aid in investigating various incidents, ranging from wireless intrusion to assault. Security operators can employ a DVR-like playback function to review what wireless devices were in a specific area at a given time. Another highly effective application combines RF detection with security video.
This sensor fusion connects the presence of RF devices to individual security video frames, enabling security departments to address some of the hard and persistent challenges associated with traditional video surveillance. For example, this RF-allowed video analytics solution 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 absent. It also enables officials to search large video archives and quickly jump to appropriate frames in recorded video, tracking people of interest across cameras and even off-camera to collect evidence. Security teams can also make a watch list of potential bad actors and be informed if they return to the agency's premises.
