Indoor Tracking Systems
Tracking systems are typically used to show on a map the locations of tracking-enabled radio devices, e.g. handheld radios. The handheld radio users can include members of
professions that may be particularly at risk, e.g. Job Centre staff or people working in known danger / trouble hotspots, e.g. security staff. The vehicle radios could be used by delivery drivers and highway maintenance crews. Tracking devices can also be attached to valuable objects where there is a risk of theft, e.g. on skips, heavy machinery, etc.
Enhanced systems may include a geo-fencing option whereby the radio system controller is alerted when a tracked device leaves a defined geographical area, e.g. when a valuable object (e.g. vehicle) is stolen or a member of staff is diverted from their expected working area. Tracking systems may also include one or more of the Man Down, Lone Worker and Emergency Alarm options. When one of these is activated the radio system controller will be automatically alerted to the location of the activated device thereby enabling security or emergency staff to attend the scene quickly. The controller software may also automatically send an email or text message to one or more recipients. The list of recipients may be filtered so that perhaps only those that are currently on shift (or off shift) will be notified. Whereas outdoor tracking systems typically rely on the orbital global positioning system (GPS) satellites to operate, indoor systems use alternative technologies A number of alternatives to GPS Tracking Systems are listed below that may be suitable for indoor use.
TRACKING BEACON SYSTEMS Tracking beacon systems offer the ability to locate users in areas where GPS tracking is not possible, e.g. within buildings. This is achieved by each enabled handheld automatically registering its position via a series strategically placed location beacons linked to a central PC. This provides a general view of user deployment and movement. For such systems you do not necessarily have to use two way radios but if you need to and would like to combine equipment, the most popular and well established solution is
i-LOC by ICOM.
When used in conjunction with other modern security systems and in particular closed-circuit television (CCTV), the system provides a detailed view of activity and staff deployment in an area. It is designed to be fully interactive to ensure dispatchers / supervisors are able to monitor and respond rapidly to situations as they occur. Another major strength with tracking is the reporting features. All radio traffic is logged and stored on a central database. This is ideal for management control and future resource planning. Analogue and digital systems are available. Digital handhelds may use 12.5 kHz or 6.25 kHz channels. A 6.25 kHz channel uses half the spectrum of an analogue system channel and therefore potentially saves money on spectrum licence fees. If a radio is placed in emergency mode, e.g. via Man-down, Lone-worker or Panic button, it transmits its position to the central PC. This can then automatically send a text message to all the other radios stating the user and position of the radio that is in the emergency mode. The case of each beacon is compact, robust and waterproof (IP-67) thus allowing easy installation indoors or out. The range of a beacon is 20 m indoors and more than 100 m outdoors (adjustable). The time between emissions from the beacons has easily programmable durations of 4, 7, 15, 30, 60, 120, 180, 300 seconds. The stand-alone battery operation avoids the cost of cabling as is often needed for other security systems. With a transmission interval of 30 seconds, the lithium ion battery version beacons have a working duration of up to 5 years. A beacon gives advance warning to the central PC to indicate when its battery needs recharging. Wall to Wall Radio Communications will be happy to discuss your tracking beacon requirements and design, install, commission, demonstrate and maintain your system. ELECTRONIC TOKEN TRACKING SYSTEMS These systems consist of specially adapted radios to scan electronic tokens / badges positioned on a predetermined route. For guard tour management, the tokens may also be located on specific items that need to be checked regularly, e.g. valuable assets and potential access points to buildings. This scan information acts as a time / date stamp and proof of patrolling. The scan information is automatically sent back to the PC of the controller. For these systems again, you do not necessarily have to use two way radio equipment but if you need to and would like to reduce other installation costs, the most popular and well established solution is i-READ by ICOM. This system is an ideal tool for managing security guard rounds, etc and verifying personnel performance in areas where GPS tracking is not possible, e.g. within buildings. Wall to Wall Radio Communications offers an electronic token / badge tracking system where the handhelds can memorise up to 16 badge checkpoints. This means that tokens can be installed in areas that are out of reach of the radio system, e.g. underground and the location data is transmitted later when the handheld is back in range. This useful function also gives the guard peace of mind from worrying about busy / blocked radio channels because the handheld memorises the checkpoint details and re-sends them automatically when the channel becomes available. When used in conjunction with other modern security systems, e.g. with closed-circuit television (CCTV), the system provides a detailed view of activity and staff deployment. The tracking system is designed to be fully interactive, ensuring dispatchers and supervisors are able to monitor and respond to incidents as they occur. It can also assist in the management and prevention of potential incidents. It is possible to visualise, in real time, all the positions of the checkpoints and the handhelds in use. It is also possible to view, file and print out all traffic. This function is ideal for future resource planning.
Wall to Wall Radio Communications will be pleased to discuss your Electronic Token / Badge Tracking systems and Guard Tour system requirements and identify suitable solutions that may include the above. BLUETOOTH TRACKING SYSTEMS Bluetooth tracking systems consist of Bluetooth sensors distributed within a building that are arranged so as to track known and / or anonymous Bluetooth devices. The known devices may be the building owner’s Bluetooth-activate handheld radios whereas the anonymous devices may be those within a number of customers’ Bluetooth-enable electronic equipment. With sufficient sensors, the locations of all Bluetooth-enabled devices (mobile phones, computers, bluetooth two way radios) may be accurately identified. This will enable the controller to track the locations of the devices as they are moved about the building. The anonymous Bluetooth devices may be those owned by customers or visitors. The monitoring of these devices may be useful to track the typical movement, or lack of movement, of people within the building, e.g. passengers through an airport, or queuing durations, e.g. to enable customer processing efficiency to be managed. Unlike wireless tracking systems, the Bluetooth sensors are connected to the central controller using IP connections. In office blocks, these connections could use the existing LAN system thereby potentially reducing the installation cost of the system. Wall to Wall Radio Communications will be pleased to discuss your Bluetooth Tracking systems requirements and identify suitable solutions that may include the above. DECT TRACKING SYSTEMSDigital Enhanced Cordless Telecommunications (DECT) tracking systems consist of DECT sensors distributed within a building that are arranged so as to
track known DECT devices. The known devices may be the building owner’s internal portable telephone handsets.
With sufficient sensors, the locations of all DECT-enabled devices may be accurately identified. This will enable the controller to track the locations of the devices as they are moved about the building.
Unlike wireless tracking systems, the DECT sensors are connected to the central controller
using IP connections. In office blocks, these connections
could use the existing LAN system thereby potentially
reducing the installation cost of the system.
