Thank you, Matt. Good afternoon and welcome to everyone. We are pleased to report fourth quarter and full year results that exceeded our expectations. Our SaaS and license revenue in the fourth quarter was $165.7 million, up 11.7% over the last year. Our adjusted EBITDA for the quarter was $46.4 million. I want to thank our service provider partners and our employees for their contributions to our 2024 performance.
We continued to see nice momentum in the business as we finished out 2024, particularly in the commercial security and EnergyHub parts of our business. On today's call, I'll review our performance in the primary areas of the business and then provide more details on our recently announced acquisition of CHeKT. In 2024, our North American residential business continued to be the largest component of our diversified business.
Our advantage in this area comes from our scale, the quality of our offerings, and the outstanding relationships we have built over the years with our service provider partners. We've been focused on this market with a sustained commitment of resources for longer than anyone else. While the market remains competitive, our service providers generally have little patience for less complete offerings. Consumer demand for professionally installed and serviced smart home security solutions remains solid.
One product that we recently released for residential, and particularly for the residential rental market, is the new Pro Thermostat HQ. This unique thermostat product connects to our cloud directly via an onboard cellular communicator. The Pro HQ does not depend on a Wi-Fi network to provide connected thermostat capabilities.
A builder that builds a home and wants to remotely control the temperature and humidity of the property before it's sold now has a connected thermostat solution that does not require an internet subscription for the property. Similarly, rental property managers frequently want to remotely manage the HVAC system for a property between tenants. These temporarily vacant properties often do not have Wi-Fi service. Property managers can now install and use the Pro Thermostat HQ to manage and monitor vacant properties all the time.
Our growth initiatives also continue to scale during 2024. These include our commercial business, the international business, and EnergyHub. Collectively, 26% of our total SaaS in 2024 was generated by these businesses. Collectively, their SaaS revenue grew nearly 25% on a year-over-year basis. I'll review each of these businesses and highlight several recent developments that provide a nice backdrop for 2025.
I'll start with our commercial business, which produced over $80 million in SaaS revenue in 2024. Physical security solutions continue to evolve into cloud-based software solutions that are more capable and cost-effective. Alarm.com purposefully designed our commercial offering to seamlessly integrate across access control, intrusion, and video monitoring all into a single cohesive platform, accessible and easily managed through a single app.
We believe that our solutions align with what the market wants, and our service provider partners offer the professional design, installation, and maintenance services that the commercial market requires. Included in our commercial business is OpenEye, our enterprise video business. OpenEye continues to post strong growth, generating nearly $20 million in SaaS revenue in 2024. As I have discussed on recent calls, Remote Video Monitoring Service, or RVM, should also further expand the addressable opportunity we have in the commercial market.
Historically, the primary use case for video solutions was to support investigations and determine when an incident occurred and who was involved. RVM is transforming video surveillance cameras by enabling them to now also deter crime before it happens. One method that we use for deterrence is to apply AI to identify certain types of activities that appear suspicious.
Our system can then engage the potential perpetrator with a generative AI voice that is dynamically tailored to the environment and the individual. We do all this in real time. Our recent acquisition of CHeKT takes this a step further and expands our position in the RVM space. We believe that CHeKT has built the best SaaS software solution for control rooms to professionally monitor properties through an array of security video cameras.
The CHeKT platform can ingest active surveillance events from nearly any video camera and enable those events to be effectively escalated and handled by control room personnel. Operators can focus on critical events, initiate deterrent activities, reduce false alarms, and speed response to threatening scenarios, and improve overall security outcomes.
