Rhombus announces Rhombus Studio, custom dashboards and mini-apps built on its open security platform.

Rhombus announces Rhombus Studio, custom dashboards and mini-apps built on its open security platform. New service delivers in-house custom-built dashboards tailored for customers' unique use business use cases. SACRAMENTO, CA, UNITED STATES, October 8, 2026 / EINPresswire.com / - Rhombus, a leader in cloud-managed physical security, today announced Rhombus Studio, a custom build service designed to turn unique operational needs into live dashboards and mini-apps for organizations across education, transportation, healthcare, retail, manufacturing, self-storage, agriculture, and other industries. Organizations today want more from their physical security systems. Cameras, access control, and sensors are already capturing an enormous amount of data every second of every day. The question is no longer just, "is my building secure?" It's "what else can this system tell me?" Every organization runs differently, and many have operational questions their security system was never designed to answer. A mulch manufacturer wants to see, count, measure, and track different types of mulch being produced from their cameras. A train yard needs to know when rail cars arrive out of sequence. A gym wants to see when its front desk goes unstaffed or how often different exercise machines are being utilized daily. A multi-site operator wants device health for every location on a single page. Until now, most physical security platforms offered the same standard dashboards and insights to every customer, no matter their industry, operational questions, or goals. Rhombus Studio closes that gap. Rhombus's in-house team works directly with customers and channel partners to define the need and create custom dashboards with Rhombus' 900+ LLM-friendly API endpoints. Each build draws live data from Rhombus cameras, IoT sensors, and access control, with AI-driven logic that can run continuously from every second to every hour. Custom dashboards are accessible directly within the Rhombus platform, with nothing extra to install or download. "Since releasing its CLI and MCP server almost a year ago, US National Times has been amazed at the response from its customers and partners. The world is no longer looking for a one-size-fits-all solution. Customers don't want a deeply embedded/closed ecosystem with a single pane of glass - they want their own custom pane of glass. However, not every customer or partner has the time or resources to build their own solutions with its CLI and MCP server. They can articulate what they want, but building/hosting/maintaining a customized solution is more than many can invest. So US National Times built Rhombus Studio - a white glove, custom built solution. Built by Rhombus, maintained by Rhombus, envisioned by its customers and partners." -Brandon Salzberg, CTO at Rhombus Channel partners can now say yes to prospects whose needs go beyond standard security platform features, without taking on custom development themselves. Where custom work on security data has typically meant engaging a third-party agency, Rhombus designs, builds, and hosts each dashboard itself, and can deliver a working proof of concept on a customer's real data. For partners who prefer to build themselves, the same experiences can be created on the open Rhombus CLI, giving teams the capability to build dashboards and experiences on their own. How Rhombus Studio Works 1. Customer purchases a customized dashboard - Customers work with the Rhombus team, through their channel partner, to define the exact problems they are looking to solve and what Rhombus can build. Rhombus will let you know what hardware is needed to bring your idea to life and connect you with an installation partner if you don't already have one. 2. Rhombus builds it - Customers get tailor-made dashboards without hiring a developer or contracting a third party, going from idea to working build in days, not months. 3. Ongoing hosting - Dashboards can be accessed within customers' Rhombus Console accounts. Each dashboard is hosted and paid annually, with pricing based on the dashboard's complexity. Custom Views into Every Part of Your Business Examples of how Rhombus Studio can support organizations include but are not limited to: - Efficiency Dashboards: Turning cameras into productivity meters that count, measure, and track output in real time. - Space and Occupancy Utilization: Understand how people actually use a physical space. See where customers go, how long areas sit empty, and when attention or staffing is needed. - Infrastructure & Systems Management: Dashboards that manage security ecosystems such as hardware health across multiple sites. - Smart Detection and Predictive Alerts: If it's recorded on camera, traced on a smart sensor, or captured with access control, it can be in your dashboard. Systems that don't just watch, but recognize a specific event or anomaly and trigger action. Any Industry. Every Use Case. Dashboards can be built with Rhombus Studio for the needs of any industry. Healthcare facilities can track PPE compliance and handwashing between patients. Schools can flag hallway activity during class periods. Construction sites can verify that subcontractors arrive wearing hard hats and other required protective equipment. The possibilities are endless. Availability Rhombus Studio is available beginning October 8, 2026, through Rhombus channel partners in all countries where compliance permits.

Rhombus announces new door controller.

Rhombus announces new door controller. The DC10 Single-Door Controller is suited for applications that need to secure only a single door, such as offices, retail storefronts, small gyms or warehouse doors far away from any other exit or entrance. Built on feedback from customers and partners, Rhombus says the new DC10 single-door controller gives you more flexibility to match hardware to each site and keep project costs in line with what the job requires. The DC10 connects a single door to the Rhombus Access Control and Security Platform. It also works as a hub for Rhombus Smart Sensors and Panic Buttons. It pairs enterprise-grade scalability with a compact design built for the tightest spaces, so you get full cloud-based access control without the complexity, Rhombus adds. Built for tight spaces. The DC10 is purpose-built for single-door installs, so you only pay for the capacity you need. Its compact, discreet design fits where larger controllers can't and can be mounted on a wall or ceiling, or in plenum spaces above air handling areas in drop ceilings due to its UL 2043 rating. Additionally, the DC10 has an IK08 impact rating, so it can hold up to knocks in tight, high-traffic areas. The open-bottom cable access lets wiring route over the controller and tuck neatly under retention tabs. With 90 W PoE++, a single cable delivers full power and connectivity, with the ability to pass both through to a nearby camera too. The DC10 also has built-in BLE connectivity which lets it act as a hub for Rhombus environmental sensors, door and window intrusion sensors, motion sensors, panic buttons and other select sensors within 100m line-of-sight, so you don't need a separate hub. Reliable cloud management. With both Ethernet and WiFi connectivity, the DC10 connects to the Rhombus cloud and keeps operating during network outages. You can manage doors from your phone or computer wherever you are, with no on-site server required. Lockdown support lets you secure entrances instantly from anywhere in the world. The DC10 plugs into the same Rhombus Platform that manages cameras, sensors and other access control hardware. It supports up to two readers, including Rhombus Readers and third-party certified (Wiegand or RS-485/OSDP), so it fits into existing deployments. It also includes one dry AUX relay for devices like low-voltage sounders, strobes or external alarm panels. Because the DC10 and DC20 run on the same platform, you can mix them across a site.

Rhombus and Gymdesk partner to connect door access directly to gym membership.

Rhombus and Gymdesk partner to connect door access directly to gym membership. Rhombus and Gymdesk integrate access control with gym memberships, automatically syncing door access, fobs, and attendance in one platform. SACRAMENTO, CA, UNITED STATES, September 10, 2026 / EINPresswire.com / - Rhombus, a leader in cloud-managed physical security, today announced an integration with Gymdesk, a gym and fitness management platform, to automatically connect door access directly to membership status for gyms, martial arts schools, and fitness studios. "Our mission at Rhombus is to build true partnerships and deliver simple, smart, and powerful solutions that fit each customer's needs. We're building the infrastructure layer for physical security, enabling companies like Gymdesk to put our cloud-based access control right inside their software, so gyms can manage members and doors together in one system." - Jeremy Gulley, Director of Ecosystem at Rhombus With the integration, Gymdesk membership status becomes the single source of truth for determining who can access the facility. When staff freeze, cancel, or renew a member in Gymdesk, Rhombus Access Control updates that person's door access automatically. Employees can use Gymdesk to issue new fobs, revoke door access, and manage member data without logging into a second system or entering information twice. Staff assign, revoke, and replace fobs directly within the member's Gymdesk profile. Every entrance through a Rhombus access control automatically logs attendance in the member's Gymdesk profile, helping teams track gym usage and anticipate staffing needs, cleaning schedules, and peak traffic periods. "Gym owners kept asking for door access that's actually tied to their memberships. When a gym member freezes or cancels their membership, the fob should stop working, without anyone maintaining a second list. We could have built our own hardware. Partnering with Rhombus was the better answer: they're excellent at access control, we stay focused on gym management software, and they built this with us rather than just selling us a product. That's the part that made it work, and it's why I'm optimistic about what comes next for our customers." - Alex Cuevas, CEO of Gymdesk Many gyms rely on separate software programs for access control and gym membership management, forcing staff to manage fobs, check-ins, and cancellations multiples times in various different platforms. This partnership closes that gap. Gymdesk owns the member relationship, Rhombus owns door access control, and the two stay in sync automatically, so access always reflects current membership. Gym owners don't have to handle installation on their own. Rhombus helps connect customers with the right reseller partner for their needs, many of whom provide professional deployment services. From planning and installation to getting the system up and running, customers can get the support they need while staying focused on running their business and protecting their employees and members. How the Integration Works Member-driven access - Freezing, canceling, or renewing a member in Gymdesk automatically updates that person's door access through Rhombus. One console, no double system entry - Staff assign, revoke, and replace fobs right from the member's Gymdesk profile, with no separate access-control system to manage. Attendance tracking - Every entrance through Rhombus Access Control logs attendance in Gymdesk automatically. Tier-based permissions - Door access is set once per membership tier, so new members inherit the right access without requiring individual configuration. Unstaffed operation - Business-hours rules and remote unlock allow gyms to offer extended or 24/7 access without staffing the front desk. Unstaffed Operation The integration is built to keep the doors running even when no one is watching them. Gyms set business-hours rules and can remotely unlock doors when needed, enabling extended or 24/7 access without dedicated front-desk staff. If internet connectivity drops, Rhombus door controllers keep working from a cached member list so members already entitled to access can still get in, and the system re-syncs with Gymdesk once the connection is restored. Gymdesk supports 4,500+ gyms, martial arts schools, and fitness studios, consolidating memberships, billing, scheduling, and attendance in one platform. Thousands of organizations trust Rhombus to secure their facilities and streamline their operations through a single, cloud-managed platform. For Gymdesk customers, Rhombus Access Control is now available as an integrated door-access solution. Organizations interested in the integrated solution can visit https://www.rhombus.com/integrations/gymdesk/ or contact Gymdesk directly.

Rhombus and CENTEGIX partner to unify video security and emergency response.

Rhombus and CENTEGIX partner to unify video security and emergency response. Share with Your Network and Follow CENTEGIX for More SACRAMENTO, CA, UNITED STATES, JULY 23, 2026 /EINPresswire.com/ - Rhombus, a leader in cloud-managed physical security, today announced a partnership with CENTEGIX(R), the nation's most-used wearable panic button provider, to integrate their complementary platforms and deliver a faster, more coordinated emergency response for organizations across education, healthcare, government, and commercial sectors. "When seconds matter most, operators shouldn't be hunting for the right camera feed. Our integration with CENTEGIX means the moment an alert fires, Rhombus is already showing you exactly what's happening." - Garrett Larsson at Rhombus The integration connects CENTEGIX's CrisisAlert TM wearable panic button with the Rhombus cloud platform, enabling security and safety teams to move from alert to action with greater speed and clarity. When a staff member activates their CrisisAlert badge, Rhombus automatically surfaces the relevant camera feeds for that precise floor and room location directly in the Rhombus Console, giving operators immediate visual context without manual searching or switching between systems. "Speed and precision save lives. CrisisAlert already pinpoints exactly where help is needed, down to the room. Our partnership with Rhombus brings live video to that same moment, leveraging existing camera investments to give responders the situational awareness to see what is happening and act without hesitation. This is what coordinated safety looks like, and it reflects our mission to protect every person during emergencies from the everyday to the extreme." - Brent Cobb, CEO of CENTEGIX Together, Rhombus and CENTEGIX address one of the most persistent challenges in safety operations: the gap between knowing an incident has occurred and understanding where it is and what is actually happening. CrisisAlert delivers room-level precision to every alert, while Rhombus delivers the live video context that turns a notification into actionable intelligence. How the integration works. * Instant camera surfacing - A CrisisAlert badge activation automatically pulls the relevant Rhombus camera feeds for the exact location of the alert, directly within the Rhombus Console. * Room-level location accuracy - CrisisAlert's precise floor-and-room-level alert data directs Rhombus to the right cameras immediately, eliminating response lag. * Unified incident response - Rhombus Alarm Monitoring can escalate incidents with live video verification, ensuring first responders have a real-time view before they arrive on scene. * Multi-sensory alert coordination - On-site CrisisAlert alerts - including strobes, intercom announcements, and screen takeovers - work in concert with Rhombus's platform-wide notifications for a synchronized, campus-wide response. * Shared situational awareness - Safety Blueprint(R) digital incident maps and Rhombus's camera network give operators and first responders a complete picture of the facility during an emergency. Instant lockdown. In a critical incident, a lockdown that depends on manual steps is a lockdown that begins too late. The Rhombus and CENTEGIX integration eliminates that dependency entirely. The moment a CrisisAlert badge is activated, Rhombus Access Control can automatically execute a lockdown sequence - securing entry points, restricting access across designated zones, and locking down the campus in real time. Security teams and administrators retain full visibility and override control through the Rhombus Console, while CENTEGIX's multi-sensory on-site alerts simultaneously direct staff and students to follow safety protocols. The result is a coordinated, automated response that compresses the time between threat detection and a secured environment to seconds. The partnership makes Rhombus a part of CENTEGIX's Platform Partner Program, an ecosystem of 80+ integrated safety and security technologies working together to compress emergency response timelines. CENTEGIX currently protects more than 18,000 locations and 18 million people across 50 states, including four of the ten largest U.S. school districts. For Rhombus customers, the integration is available through the Rhombus Console. For CENTEGIX customers, Rhombus is now available as a certified platform partner. Organizations interested in deploying the integrated solution can visit www.rhombus.com or contact CENTEGIX directly.
