Monitoring & Protection for Newborn Babies

Electronic protection system for newborns with alarm function and mother-child connection.



Reliable protection for newborns

The swapping or even abduction of newborns occurs time and again in maternity wards in hospitals. Even if the cases are usually solved quickly, the experience is traumatizing for everyone involved. The hospitals affected are confronted with a loss of reputation and financial damage.

The BabyGuard® solution provides full protection to ensure that babies can only leave supervised areas with authorized persons, such as parents or nurses. In case of unauthorized leaving of an assigned area, an alarm is immediately sent to the staff.

The system enables many other administrative functions, alarm options and automated reporting through integration with a hospital's nurse call system.

  • Essential basic protection to prevent newborns from being switched or abducted
  • Clear assignment of parents and newborns
  • Monitored protection zones for reliable alerting of caregivers in case of separation of mother and child
  • Uncomplicated use even with multiple births

LCA 500LCA 500 ELA
LCA 500 Locator

LCA 500

The Locator LCA 500 is installed in the center of the zone to be monitored. This can be individual rooms or the passage area of a door. It transmits a permanent alarm signal in the LF frequency range at 125 kHz with an adjustable extension of approx. 1 - 5 m. Each alarm field is identified by a unique location code for communication with the amanTag® transponders located in the reading range of the locator. A UHF transceiver is integrated in the locator for bidirectional communication with the amanTag® transponders. The LCA 500 locator can be operated standalone or online.

  • Comprehensive range of functions for effective baby protection
  • Simultaneous identification of up to 10 persons
  • Standalone and online operation
  • Compact design
  • Optional system configuration for alarm field extension and direction detection
LCA 500 ELA Locator


Compared to the LCA 500, which is equipped with an integrated loop antenna for generating the alarm field at 125 kHz, the LCA 500 ELA has been designed for use with specified loop antennas, which are available in different design variants on site as door frame antennas, wall antennas or, in outdoor areas, as floor antennas. Antennas of this design allow a very precise definition and thus application-specific expansion of the wake-up field. The matching electronics integrated in the locator allow the connection of external loop antennas with a wide range of values of assigned inductances.

  • Integration into and retrofitting of existing installations
  • Concealed installation of the locator possible, e.g. in suspended ceilings
  • Simple connection to loop antennas installed in the door, wall or floor area


Baby Transponder


Baby transponder

The active BTA 1 Baby-Tag protects the newborn from abduction and swapping. During development, emphasis was placed on achieving minimal weight of the transponder while ensuring optimal performance, in order to avoid unnecessary burden on the newborn and guarantee the best possible protection. Without restricting freedom of movement, the tag can be worn in a diaper with an insert pocket. When entering the wake field of an amanTag® Locator, an alarm is triggered if the baby is not accompanied by its mother, an authorized caregiver, or nursing staff whose identification is associated with the baby tag through mother or companion transponders.

  • Protection against abduction and mix-up
  • Alarm when baby is unattended
  • In-house locating of mother and baby
Mother transponder


Mother transponder

The active UTA 3 mother transponder is used for authorized crossing and exiting of defined protection zones with an associated baby without triggering an alarm. If the corresponding BTA 1 baby transponder enters the wake field of an amanTag® Locator without the accompaniment of the UTA 3 mother transponder, an alarm is triggered. This effectively addresses the risk of abduction or swapping of newborns by providing immediate and reliable information to the nursing staff.

  • Alarm when baby is unattended
  • In-house locating of mother and baby
Mother and staff transponder


Mother and nurse transponder

The UTA 1 can be used as an alternative to the UTA 3 as a mother transponder and can also be worn by nursing staff in maternity wards. The additional push-button is used to trigger an assistance call incl. an area identifier while on the move, which is received within a radius of 25 m to generate an emergency call for immediate information of the nursing or security staff. The LED integrated in the UTA 1 is used to display a status message after pressing the push-button.

  • Mobile emergency call to nursing and security personnel
  • Feedback on successful transmission of the emergency call via integrated LED
  • In-house location detection

Installer Transponder

The ITA 3 is a special transponder that can be used by staff from the areas of building management, service and maintenance. Thus, without the use of additional software, the extension of the wake-up area of a locator can be adapted to the concrete needs directly on site. For this purpose, the transponder has three buttons. A test call can be triggered via the large call button. The alarm field of the locator can be enlarged or reduced via the small buttons. An integrated LED indicates that the transponder is in the alarm field. Thus, the extension of a protection zone can be optimally set with this transponder and checked at regular intervals.

  • Intuitive setting and checking of the alarm field expansion for defining a protection zone
  • On-site configuration of the locator by service technicians without additional software
  • Integrated LED for checking the expansion of the Locator alarm field

Benefits of our solution

Relief for the nursing staff  Baby snatching

Staff relief

Digitization supports nursing staff

Technical assistance systems serve to support nursing staff in order to still meet the demand for patient care at a high level in times of nursing shortage. The Baby Monitoring System takes on the task of ensuring the safety of newborns. Consistent integration into the daily routine on maternity wards reduces the risk of newborns being mixed up or even abducted.

Monitoring the movement of mothers and children in defined protection zones guarantees a reliable alerting of the nursing staff in order to interrupt the treatment care and the daily routine of the nursing staff only in emergencies.

Powerful system performance

Best conditions for patient monitoring

The BabyGuard system is based on amanTag® technology, which uses dual frequency technology for transponder activation and bidirectional communication. On the one hand, this enables the localisation of people and, on the other hand, creates the prerequisite for generating an alarm even outside the activation range of a locator.

The identification of several persons who are simultaneously in the wake-up field of a locator, e.g. in the passage area of a door, is easily possible due to the implementation of a sophisticated anti-collision detection method.

Baby snatching direction recognition

Flexible extensibility

Adaptation of the functional scope of the system configuration

Combining multiple locators into a network with a local primary allows for an expansion of the activation range. By connecting additional replicas to a primary, overlapping wake fields can be easily achieved. This enables the extension of the protection zone through the integration of existing equipment in a straightforward manner, ensuring the secure monitoring of large areas.

An additional level of expansion is achieved through a synchronized primary-replica configuration with overlapping wake fields, which not only allows locating the whereabouts of individuals but also enables a clear detection of their movement direction. This additional information can be of paramount importance to the nursing staff for identifying the location of newborns.
