Drowning detection system
There are three broad classes of pool safety cameras:
- remote monitoring;
- seeing aids for lifeguards;
- cameras for automated drowning detection.
Remote monitoring is often less effective because of problems getting to the pool quickly enough to intervene. Remote monitoring includes the recording of video for insurance purposes, to prove that there was no negligence on the part of the pool operator, or the like (e.g. evidence of horseplay, drunkenness, etc., leading up to an incident, might reduce liability).
Seeing aids for lifeguards can help to see under water, or to monitor a facility from various viewpoints simultaneously.
Systems such as the "swimguard" are suitable for large waterparks, bathing complexes, etc., where a variety of different kinds of swimming baths are present.
Computerized drowning detection systems, such as Poseidon, DEWS (Drowning Early Warning System) are often limited to swim-only pools, and may be less effective in the chaotic environment of a wave pool, whirlpool, jacuzzi, or inner-tube ride.
The poseidon system has been installed and used in a number of indoor pools, but is not yet operational in any outdoor pool, wave pool, or whirlpool.
The DEWS was designed specifically for use in outdoor pools.
