Core offering

CLB develops, manufactures, installs, and services IP-based acoustic monitoring and nurse call systems for hospitals and care homes. Its integrated portfolio includes C-series hardware modules (controllers, acoustic monitoring modules, nurse call modules, handsets, sensors, wireless peripherals), S-series software (Event Handler, Report Generator, Configurator, Care Assignment Planning), and A-series mobile apps (Medical Messenger, Smart Messenger, Emergency Messenger, Nurse Call Display). The Acoustic Monitoring system continuously listens to room sounds using third-generation sound recognition to detect distress while filtering ambient noise, alerting staff when sound profiles exceed individually set thresholds.

Product overview

CLB offers an integrated Acoustic Monitoring and Nurse Call system for healthcare facilities. The portfolio consists of three product series: C-Series hardware modules (including controllers, acoustic monitoring modules, nurse call modules, handsets, sensors, and wireless peripherals), A-Series mobile apps (CLB Messenger with Medical/Smart/Emergency variants and Nurse Call Display), and S-Series software (Event Handler, Report Generator, Configurator, and Care Assignment Planning). The system connects room-based modules via IP network using Power over Ethernet, with alarms distributed to central stations, PCs, and mobile devices. The WAMM provides a wireless alternative for retrofit installations. CLB's Acoustic Monitoring solution continuously monitors room sounds using up to third-generation sound recognition technology to detect distress while filtering ambient noise.

Scale indicators7 records

Recent moves6 records

Expansion highlights5 records

Emerging players

• Status Solutions: US-based sensor-based situational awareness and notification platform for senior living and healthcare. Comparable in using environmental sensors (including acoustic) to generate staff alerts, but more software/platform-oriented and earlier-stage in elderly care.
• Aiva Health: Voice-first care platform for senior living that uses ambient listening and conversational AI to surface resident needs. Comparable in the acoustic/voice-monitoring thesis for elderly care but emerging and software-only versus CLB's integrated hardware+software platform.

Direct peers

• Rauland-Borg (AMETEK): US manufacturer of nurse call and clinical communication systems (Rauland Responder), now part of AMETEK. Direct competitor in IP-based nurse call infrastructure for hospitals and senior living, with overlapping product categories (modules, controllers, mobile apps).
• Tunstall Healthcare: UK-headquartered provider of telecare, telehealth and nurse call solutions for elderly and dementia care. Direct competitor in the same institutional elderly-care segment that CLB targets, with comparable acoustic/telecare offerings and a similar European footprint.
• Securitas Healthcare (formerly Stanley Healthcare): Provider of patient safety, infant protection, and real-time location systems for hospitals and senior living. Comparable in delivering continuous monitoring and alerting infrastructure for care facilities, with an overlapping customer base in elderly care and hospitals.
• Ascom: Swiss-listed provider of mission-critical communication and nurse call systems for hospitals and care homes. Closely comparable IP-based architecture, mobile alerting apps, and enterprise healthcare sales motion, with a similar focus on alarm distribution to staff handsets.
• Vigil Health Solutions: Canadian provider of call systems and remote monitoring for senior living. Closely comparable in scope (nurse call + wireless monitoring + fall/behavior alerts) and customer type (long-term care operators), serving a comparable institutional elderly-care niche.

Broad incumbents

• Legrand: French electrical and digital building infrastructure group with a healthcare communication and nurse call offering. Comparable in IP-based patient communication systems and European healthcare customer base, but as one segment within a very large building-systems portfolio.
• Bosch Healthcare: Division of the Bosch group offering healthcare communication and nurse call solutions for hospitals and care facilities across Europe. Overlaps with CLB on IP-based nurse call and elderly-care deployments but as part of Bosch's much larger industrial and building portfolio.
• Honeywell (Ackermann nurse call): Global building-automation conglomerate whose healthcare portfolio includes the Ackermann nurse call line. Overlaps with CLB on nurse call modules, controller architecture and hospital alarm distribution, but operates across a much broader building-systems portfolio.
