Who comes in. When they came in. What happened next.

Access control and video security in the same console. Every door event linked to camera footage automatically. No switching between systems. No gaps in your audit trail. Rhombus access control covers every entry point — loading docks, service corridors, back of house, executive areas, pool gates — managed from the same platform as every camera on your property.

Hardware · Every Entry Point Covered

Four products. Every door scenario a hotel faces.

Main Entrances · Two-Way Audio · Video Verification

DR40 Video Intercom

Your front door, back of house entrance, or loading dock in one device. The DR40 combines video intercom, access control reader, and two-way audio into a single unit. Staff verify visitors visually before granting access. Guests communicate directly with the front desk remotely. Every interaction is logged with timestamped video. Perfect for after-hours entrances, service areas, and any access point where visual verification matters before entry is granted.

All Entry Points · Mobile · Card · Fob

DR20 Door Reader

The standard reader for controlled access points throughout a property. Supports mobile access via phone, keycards, and fobs. Fast, reliable tap-to-enter performance. Ideal for fitness centers, spa areas, back-of-house corridors, storage rooms, server rooms, and any space where access needs to be controlled and logged without the full video intercom feature set. PoE powered — one cable installation.

Infrastructure · Powers Everything

DC20 Door Controller

The brain behind every Rhombus access control deployment. The DC20 connects your door hardware — electric strikes, magnetic locks, REX sensors — to the Rhombus platform. Compact and PoE powered. Supports up to two doors per controller. Communicates directly with the Rhombus cloud so every access event is logged and linked to camera footage in real time. No additional software, no separate server, no IT involvement required.

Credentials · Mobile · Card · Fob

Secure Cards & Fobs

Rhombus Secure Cards and Secure Fobs use encrypted credential technology that prevents cloning and unauthorized duplication — unlike standard hotel keycards which are trivially duplicated. Issue credentials directly from the Rhombus console. Revoke access instantly from any device. Temporary credentials for contractors and vendors expire automatically. For properties managing multiple staff access levels across dozens of controlled areas, the credential management alone saves hours per week.

The Unified Console Advantage

Every access event. Every camera angle. One platform.

When a door event happens — authorized entry, failed credential, forced entry, door held open — the Rhombus console automatically links that event to the nearest camera footage. Your security team sees who entered, when, what they looked like, and what happened in the area immediately after. No manual correlation. No toggling between systems. No missing the context that matters.

Loading Dock Management

Every vendor, contractor, and delivery driver logged by credential and by face. Time-stamped video of every loading dock entry. If inventory goes missing or a claim arises, you have a complete record — who entered, when, what the camera saw. No more relying on paper sign-in sheets or badge swipe logs that don't tell the whole story.

After-Hours Access Control

Set automatic access schedules by credential level. A night-shift kitchen crew member's card only works during their scheduled hours. A contractor's temporary fob expires at the end of their project date. An executive credential works 24/7. All managed from the Rhombus console without calling IT or reprogramming hardware at the door.

Incident Investigation

When something happens — a guest complaint, a missing item, a liability event — Rhombus gives you the complete picture. Search by time, by door, by credential, or by face. The AI Search feature lets you type what you're looking for in plain English and pulls both the access log and the relevant camera footage simultaneously. What used to take hours takes seconds.

The access control and camera integration is what separates Rhombus from every system I evaluated. Other platforms give you a door log and a camera system that don't talk to each other. With Rhombus, every door event has video attached automatically. For a property manager running a liability-conscious luxury hotel, that's not a feature — it's the entire value proposition.
