Question: Can the AngelEye system be installed in all types of swimming pools?

Answer: Yes it can. The AngelEye system is suitable for all pool designs and materials, including concrete, steel and fibreglass. The system is adaptable to all shapes and sizes because drowning detection sensors are easy to orientate.
If you need to minimize the number of sensor housings in the pools, special optical detectors can be used to increase the field of action of the sensors (thus reducing their number).
The installation of the ‘camera boxes’ in the pool requires suitable planning and activities must be supervised by AngelEye’s technical team.

Question: How can the system detect drowning?

Answer: The central processing unit is constantly receiving images from the detection sensors. These images are then processed by dedicated software that determines the presence of swimmers in the pool, studies their movements and uses algorithms to interpret their behaviour.
If the person is believed to be having trouble moving or if the body does not emerge on the surface, the system issues an alert.

Question: How do the lifeguards interact with the system?

Answer: When the AngelEye system generates an alarm, the lifeguards’ signalling devices get activated. These devices include both poolside units, such as the low voltage waterproof touch screen monitor, and mobile units that lifeguards always carry with them (crossbody case, pocket of the uniform, wrist cases). These handheld devices can therefore signal an alarm in progress and tell the lifeguard where the danger was detected - number of pool, position inside the pool; in addition, thanks to the live streaming option, the event can be seen live on the screen of the handheld device. Smartphones, such as the iPhone or Android – based devices, can be used for that purpose (after installing the suitable app).

Question: Does the drowning prevention system generate many false alarms?

Answer: Algorithms used to detect dangerous situations and generate alarms are complex and ever-changing. A team of developers is constantly working to update the processing software. However, situations of alleged danger can be identified, which are in fact not dangerous at all.
Typical alarms involve pool users performing apnea diving, an activity which is often prohibited in swimming pools and subject to mandatory reporting to the lifeguards.
An apnea-related event is in fact a potentially hazardous situation, worthy of reporting to the lifeguards, hence the warning. Alerts however are sent only to the lifeguards and rescue personnel to avoid panic among pool users.

Question: Do pool safety procedures change after installing the AngelEye system?

Answer: The use of an electronic drowning prevention system only changes the way in which lifeguards or rescue personnel receive the alarm, it does not affect their response and behaviour after being alerted. In pools equipped with the AngelEye system, vigilance is performed both by the lifeguards and the system, which is constantly watching the pool bottom area.
All other activities remain unchanged.

Question: Is it possible to equip the pools of a facility with the video surveillance system at different points in time, i.e. expand the system from one pool to another? How does it work?

Answer: In a multi-pool swimming facility the AngelEye system can be installed in several stages. The central processing unit can manage several pools (depending on the model chosen).
The first stage may include the installation of the central unit and the detectors in one pool. Then, the video surveillance can be extended to each of the other pools.
Due to the need to install the central processing unit, the investment for the first pool is obviously greater than that for later pools. The investment in later stages is limited to the sensors for additional pools and related construction works.

Question: Is the AngelEye system certified and required by law?

Answer: Not all countries have legislation covering the use of electronic drowning detection systems. Unfortunately Italy does not have such law, unlike other European countries, which are more far-sighted and attentive to the safety of their citizens.
AngelEye is committed to raising relevant authorities’ awareness of the issue, thus encouraging a revision of the legislation.
Some US States and some countries in other continents have developed legislation to improve the safety of their pools.
AngelEye is currently involved in drafting the standard concerning drowning prevention systems for swimming pools in Germany, as a consultant to the DIN (Deutsches Institut für Normen).

In many countries, the legislation provides for the use of technologies available on the market to enhance pool safety. Today AngelEye is a consolidated presence on the market, and swimming pool managers need to be prepared to face the consequences of failing to adopt a drowning prevention system.

Question: What type of maintenance does the system require – if any?

Answer: The system requires minimum maintenance.
As regards the central processing unit, maintenance is performed by the AngelEye staff via remote assistance on a daily basis.
The system is self-alarming, i.e. it is able to automatically detect faults and notify them promptly to AngelEye’s technical team, who will take immediate action.

Question: Can the AngelEye system be installed in outdoor swimming pools that remain open also during the winter months?

Answer: Thanks to the very high quality of its components, the AngelEye system can be used in extreme operating conditions (temperatures from 0 to over 50 degrees) and can withstand thermal shocks.
The system is strongly recommended especially for outdoor swimming pools open in the winter period. These pools are in fact subject to “steam fog” on the surface, which prevents lifeguards from being able to detect potential danger in an accurate way. In addition, according to a study on the lifeguard activities, it appears that in winter lifeguards do not always watch over activities in outdoor pools from the poolside; in most cases, they stay in the indoor pool and monitor the outdoor pool through a window. This reduces the quality of vision remarkably, increasing the risk that users in distress do not receive help when they need it most.
