The SenTAG concept is simple

Each bather wears a wristband that monitors the ‘status’ of the individual by analysing their relative motion and depth.   Wristbands continually consider the pattern of behaviour / position and produce wireless ‘alerts’ if the wearer is determined as being outside of set limits.  Before this occurs the wearer is prompted to return to a ‘safe location’ just before the alert it transmitted by the wristband producing both sound and light indication – if they respond appropriately the alert is not transmitted.  This greatly reduces ‘false positives’ without applying ‘higher’ than necessary safety thresholds.  SenTAG uses both radio and in-water ultrasonic signalling.   

The SenTAG system is easy to apply

Signals are analysed by highly developed hydrophone receivers before qualified ‘alerts’ are passed on to the rest of the system.  For installation at existing pools a battery powered ‘stand-alone’ receiver that retransmits signals to the rest of the system can completely negate the need for complex in-pool installation and cabling.  These can be clipped to existing pool access steps or to the pool wall.  These units are simply removed from the pooland recharged overnight every 90 days.  SenTAG can also monitor the status of bathers above the surface, and even whether wristbands have been removed.

A powerful management tool

Supervisory staff have access to clear, simple to use management information.  This can include detailed analysis of ‘incidents’, information showing pool usage patterns, system use and much more.  In short the system is highly flexible and can be effectively configured for both the smallest single pool site as well as for the largest multi-site operator who may want to monitor a large number of sites centrally.

It works with existing practices

Applying SenTAG is easy.  Pool supervisors can be prompted by dedicated personal pagers that link directly to the system as well as by other system elements.   The system can also activate pre-existing pool alert systems (visual /audible) by using inbuilt integral low voltage terminals. System ‘alerts’ are intended to prompt supervisors to immediately check out their area or responsibility or to follow any other contingency plan if they are not already at pool side.

It can be integrated with locker and access control systems

SenTAG wristbands can incorporate 'stand-alone' passive RFID devices as used in electronic locker and access control technology. Alternatively the wristband can be configured to emulate RFID protocols via their active RF capability.

IIntegration makes sense for many operators. Locker and access control specialists are particularly interested in the approach and SenTAG welcomes technical or commercial enquiries.

Wristbands are capable of providing pool safety cover, access control and locker capability and even on-site tracking. The wristband can even be 'pre-loaded' with cash to facilitate on-site expenditure by the wearer. All via the SenTAG wristband.

Humans are exceptional – once  they recognise an incident is in progress.   SenTAG alerts provide timely prompting that exploits this ‘event driven’ superiority.
