Honeywell, a US-based industrial technology group supplying building automation systems, has agreed to offer cloud video products from Rhombus as it expands the security business acquired from Carrier Global in 2024.
Rhombus, a cloud-managed physical security company, will contribute video management and AI analytics to a system combining those functions with Honeywell’s access-control technology. Honeywell will initially offer Rhombus products in North America, with deployment in other regions due to follow.
The agreement covers product integration and resale through Honeywell’s channel partners and systems integrators. The companies also plan to connect Rhombus’ AI analytics directly with Honeywell access-control platforms.
Honeywell builds on Carrier security acquisition
Honeywell completed its $4.95bn acquisition of Carrier’s Global Access Solutions business in June 2024. The transaction added LenelS2, Onity and Supra, along with approximately 1,200 employees, to Honeywell’s building automation operations.
Honeywell said the acquired operations and its existing security portfolio were expected to produce combined annual sales of more than $1bn. LenelS2 brought access-control products including OnGuard and NetBox.
Cloud security was already part of the LenelS2 portfolio. Before the Honeywell acquisition, the business offered OnGuard Cloud and the native-cloud Elements platform, which included video capabilities through an integration with Milestone XProtect.
The Rhombus agreement therefore expands Honeywell’s cloud-video options rather than introducing them for the first time. The proposed system will allow customers to manage access control and video through one cloud solution.
Rhombus adds AI analysis to security video
The Rhombus platform covers cameras, access control, sensors, alarm monitoring and third-party integrations. Its analytics can search recorded video, identify activity patterns and provide information about the use of physical spaces.
Rhombus Insights allows customers to configure AI prompts for analysing activity. The company says the results can help users investigate incidents and examine how areas within buildings are being used.
A Rhombus article published in February 2026 described natural-language video searches, automatic detection of events such as loitering and occupancy counting, and alerts generated when specified activity is detected.
Rhombus had also introduced Relay in March 2025 to connect compatible third-party cameras to its cloud platform.
The combined Honeywell and Rhombus system is intended for organisations with distributed properties, including retail chains, fitness centres and schools.
Cloud video solutions are growing by more than 20% annually and are forecast to remain the security industry’s fastest-growing segment through 2029, according to Omdia data cited by Honeywell.
