Short answer: If you run LenelS2 OnGuard, NetBox or Elements, you can add AI-based entry without starting over. Edge.AI by Proptech.AI connects to existing access control panels via Wiegand, adding facial recognition, app-free QR codes and analytics while LenelS2 keeps running, or it can replace the system as a standalone platform. Reusing the panels and wiring you already own keeps the upfront cost of AI entry low.
Key takeaways
- LenelS2 is a Honeywell brand whose portfolio includes OnGuard, OnGuard Cloud, NetBox, Elements, BlueDiamond credentials and the Magic Monitor client.
- LenelS2 runs on-premises or in the cloud, and its Elements datasheet lists the LNL controller families as non-proprietary Mercury hardware.
- LenelS2 offers facial recognition through factory-certified partners in its OpenAccess Alliance Program, which lists more than 200 certified interfaces.
- Edge.AI by Proptech.AI can join a LenelS2 site through Wiegand integration, run in parallel or hybrid mode, or replace LenelS2 entirely.
- LenelS2 suits complex enterprises with deep integrations, and Edge.AI suits teams that want hands-free entry and visitor flow without a rip-and-replace.

Where LenelS2 is strong
LenelS2’s strengths are enterprise depth, deployment choice and a large partner ecosystem. LenelS2 calls itself the global leader in advanced physical security solutions, and it is a Honeywell brand: Honeywell completed its acquisition of Carrier’s Global Access Solutions business, including LenelS2, in June 2024.
OnGuard exchanges cardholder data with HR and ERP platforms, coordinates alarms with emergency response systems, connects to elevator and building systems, and scales to multi-server deployments with OnGuard Enterprise.
- Deployment choice: on-prem OnGuard and NetBox, OnGuard Cloud as single-tenant SaaS on AWS with 24/7 monitoring, and cloud-first Elements.
- Open ecosystem: more than 200 certified OpenAccess Alliance Program interfaces, Mercury platinum premier partner status, and BlueDiamond readers that support Wiegand and OSDP.
- Wallet credentials: Apple Wallet and Google Wallet badges through BlueDiamond for NetBox and OnGuard in North America.
- Situational awareness: Magic Monitor unifies access control, video and live internet feeds for security operations centers.
- Industry depth: education, healthcare, government, transportation, manufacturing, energy, data centers and commercial real estate.
If you run a security operations center or depend on HR and alarm integrations, LenelS2’s depth is a strong reason to keep it and add capabilities around it.
Where Edge.AI is different
Edge.AI treats AI identity at the door as the main capability, with facial recognition, QR codes, RFID cards, visitor invites and analytics in one subscription platform, as the Edge.AI facial recognition access control page describes.
Facial recognition without stitching partners together
With LenelS2, face-based entry comes from an OpenAccess Alliance Program partner, and the partner face interfaces we reviewed on LenelS2’s site each require an OnGuard API license. Edge.AI by Proptech.AI includes facial recognition natively at doors, turnstiles and elevators. Proptech.AI specifies 99.9% accuracy from multiple sensors, and Edge.AI alerts on spoofing and fraud attempts.
App-less enrollment and calendar-based visitors
Enrollment happens by email rather than at a badging desk: each person takes a selfie and uploads it, with biometric privacy consent as the first step, and has access on the next arrival. Visitors get invites through Outlook, Google Calendar and other native calendars, pre-check-in on their phones, and hosts are notified on arrival.
At 330 Madison in New York City, where hundreds of people move through the building every minute, Proptech.AI used Appless Self Enrollment and facial recognition, integrated with the building’s turnstiles and card-based access control system.
Analytics separated from identity
Edge.AI reports building usage, people counting, peak hours, unique visitors and popular areas across a portfolio. The analytics platform is separated from the management console, and its data is tokenized and stripped of PII.
Split hardware, privacy and hosting
Legacy single-appliance biometric readers can expose network connections, lock relays or panel wiring if pulled off the wall, and can be stolen along with user data; Edge.AI’s split device keeps those away from the user-facing unit. Consent forms state that data is not sold to third parties or used without authorization, all data can be deleted on request, and PII is separated from the device and the management console. You can host Edge.AI in the cloud or on-premises.
Under GDPR Article 9, biometric data used to uniquely identify a person is special-category data, so review your approach with counsel. This is general information, not legal advice. Whichever face solution you evaluate, ask about independent testing such as NIST’s Face Recognition Technology Evaluation.
How do you add Edge.AI to an existing LenelS2 system?
Treat Edge.AI as a proptech layer for LenelS2 today or as a replacement later. LenelS2 controller datasheets, such as the LNL-M4420’s, list Wiegand among supported reader inputs, the connection Edge.AI’s integrated mode uses; confirm models and card formats with Proptech.AI.
- Integrated: keep OnGuard, NetBox or Elements and connect Edge.AI to the existing panels via Wiegand. LenelS2 keeps managing access levels, alarms and reports while Edge.AI adds facial recognition, QR codes and analytics.
- Parallel: pilot Edge.AI at one lobby or amenity while LenelS2 continues unchanged elsewhere.
- Hybrid: integrate Edge.AI at the lobby turnstiles and run it standalone on amenity doors outside the LenelS2 system.
- Full replacement: Edge.AI is a standalone access control system and can replace LenelS2, for example when servers or support plans come up for renewal. Map integrations such as HR feeds, alarms and video, and ask Proptech.AI how each will be handled.
101 Greenwich in New York City, a JLL-managed building with 1,500 tenants, took the integrated route: six Edge.AI sensors were installed on six turnstiles and integrated with the existing card-based system for 24/7 secure access.
“Proptech.AI’s Edge solution was the missing piece to our security puzzle at 101 Greenwich. We replaced our limited access control system with six Edge.AI sensors installed on six turnstiles, resulting in unparalleled security and 24/7 secure access.”
Jones Lang LaSalle, 101 Greenwich

Cost of ownership: what to compare
Enterprise systems carry costs that rarely appear on a hardware quote. Before you extend or replace LenelS2, compare these categories:
- Software support: support plans such as the OnGuard Software Upgrade and Support Plan, versus a subscription.
- Servers and IT time: patching, backups and upgrade projects, or the hosting model you choose.
- Add-on licenses: partner face interfaces, per-iPad visitor kiosks and API access.
- Integrator labor: reseller hours for programming, readers and turnstiles.
- Badging: card stock, printers and lost-card replacement.
- Lobby staffing: guard and reception hours for visitors and badge exceptions.
- Migration risk: downtime, retraining and data migration.
- Privacy obligations: consent capture, retention and deletion workflows.
Proptech.AI offers Edge.AI by subscription and does not publish prices, so request a quote for the doors and turnstiles in scope. Integrated and hybrid modes reuse LenelS2 panels and wiring, so you can prove the value of AI entry before committing to a larger proptech investment.
Which should you choose?
Most LenelS2 owners face three paths: stay, extend or replace.
- Stay with LenelS2 alone if deep HR, alarm and elevator integrations, a Magic Monitor operations center and an OnGuard-managed face partner are your priorities.
- Add Edge.AI to LenelS2 if the system works but turnstile queues, tenant onboarding and visitor check-in are daily pain points.
- Go hybrid to cover amenities that LenelS2 does not reach today while integrating at the lobby.
- Replace LenelS2 with Edge.AI if a server refresh or support renewal is near and your needs center on doors, turnstiles, elevators and visitors.

Frequently asked questions
Proptech.AI can be a good alternative to LenelS2 for properties whose needs center on doors, turnstiles, elevators and visitors, and Edge.AI can also complement LenelS2 rather than replace it. Edge.AI by Proptech.AI combines native facial recognition, app-free mobile QR codes and RFID cards with built-in visitor management and analytics, hosted in the cloud or on-prem. LenelS2 remains a strong choice for large enterprises that rely on OnGuard’s deep integrations with HR, alarm and building systems.
Edge.AI can work with an existing LenelS2 system through its integrated deployment mode, which connects Edge.AI to existing access control panels via Wiegand so the current system keeps running. LenelS2 controller datasheets, such as the one for the LNL-M4420, list Wiegand among supported reader inputs, but controller models and card formats should be confirmed with Proptech.AI. Edge.AI can also run in parallel, operate in a hybrid setup, or replace LenelS2 as a standalone access control system.
LenelS2 offers facial recognition through partners in its OpenAccess Alliance Program, which lists more than 200 factory-certified product interfaces. Examples on LenelS2’s site include NEC’s enterprise video analytics and CyberExtruder’s Aureus Insight, and those partner listings note that each interface requires an OnGuard API license. Edge.AI by Proptech.AI includes facial recognition natively, together with mobile QR codes and RFID cards, and can connect to existing panels via Wiegand.
Replacing OnGuard servers is not required to use Edge.AI. In integrated mode, Edge.AI connects to existing access control panels via Wiegand while the current system keeps running, and in parallel or hybrid mode Edge.AI runs alongside it. If a full replacement makes sense later, Edge.AI can operate as a standalone access control system, hosted in the cloud or on-prem, which lets an organization retire legacy servers on its own timeline.
LenelS2 is a Honeywell brand. Honeywell completed its acquisition of Carrier’s Global Access Solutions business, which included LenelS2, Onity and Supra, in June 2024. After spinning off its aerospace business in June 2026, Honeywell’s remaining automation company, which includes building automation, operates as Honeywell Technologies. Proptech.AI is not affiliated with LenelS2 or Honeywell, and this comparison reflects publicly available information as of November 2026.
