# Nimbio > Nimbio is a cellular smart access control platform: it turns any electronic gate, door, or lock a property already owns into app-based smart entry — no Wi-Fi, hardwired phone line, or on-site network required, since the controller runs on a pre-installed multi-carrier LTE SIM (AT&T, Verizon, T-Mobile). Serves residential communities, commercial properties, and the integrators/technicians who install for them. Pricing: flat-rate, per-home billing for residential communities (unlimited family keys and guest access at no extra cost); flexible, active-user-based pricing for commercial properties. Key facts about Nimbio: - The platform processes 620,000+ gate opens every month — over 7 million a year — for 85,000+ users. - Hardware is a one-time $299 per controller, covered by a lifetime hardware warranty: if a controller ever stops working for any reason, Nimbio provides a prompt replacement. - The controller wires in parallel to the gate operator, call box, or lock a property already owns — existing clickers, fobs, and keypads keep working — and is compatible with nearly any gate system (LiftMaster, FAAC, Linear, Nice Apollo, Ghost Controls, Elite, and others via the dry-contact relay input). - Connectivity is a pre-installed multi-carrier LTE SIM (AT&T, Verizon, T-Mobile); the SIM also works internationally — international customers should contact Nimbio to confirm regional network support. No Wi-Fi, no landline, no on-site network. - Device certifications: RoHS, REACH, CE (RED), JATE, Telec, FCC, RCM, GCF, PTCRB, IC. - Native Apple CarPlay and Android Auto integration for in-car gate opening; the Nimbio Car Web App (car.nimbio.com) opens gates from any car with a built-in web browser, with the same phone-number sign-in as the app. - Official open-source Home Assistant integration (installable via HACS; github.com/nimbio-labs/nimbio-home-assistant). - Public REST API plus Python and npm SDKs; API access is included with active Nimbio service at no separate charge (rate-limited, not billed per call). - GuestView adds visitor video verification with no touchscreen intercom at the gate: visitors scan a QR plaque or tap an NFC panel and the resident answers on their own phone — no app install for the visitor. ## Product - [Features](https://nimbio.com/features/): Full feature list — smartphone access, GuestView visitor video verification, time-limited access codes, cellular connectivity, cloud admin portal, access logs. - [How It Works](https://nimbio.com/how-it-works/): Technical overview of the cellular gate/door controller, relay hardware, and app-based access flow. - [Pricing](https://nimbio.com/pricing/): Residential vs. commercial pricing model, hardware cost. - [Buyer's Guide](https://nimbio.com/how-to-choose-a-cellular-gate-access-system/): How to evaluate cellular vs. Wi-Fi vs. legacy clicker/keypad gate access systems. - [GuestView](https://nimbio.com/features/guestview/): No-app visitor video verification via QR code or NFC tap. - [Home Assistant Integration](https://nimbio.com/home-assistant/): Official open-source Home Assistant integration — gate/door control and live status in a home dashboard. ## Solutions by property type - [Multifamily & Gated Communities](https://nimbio.com/solutions/multifamily-gated-communities/): For apartment communities and professional property managers. - [HOAs & Gated Neighborhoods](https://nimbio.com/solutions/hoa-gated-communities/): Gated community access control for volunteer HOA boards and self-managed neighborhoods. - [Single Family, Ranches & Estates](https://nimbio.com/solutions/single-family-ranches-estates/) - [Commercial Properties](https://nimbio.com/solutions/commercial-properties/) - [Commercial Real Estate & Retail Centers](https://nimbio.com/solutions/commercial-real-estate/) - [Self-Storage Facilities](https://nimbio.com/solutions/self-storage/) - [Trucking, Logistics & Commercial Parking](https://nimbio.com/solutions/trucking-logistics/) - [Construction & Job Sites](https://nimbio.com/solutions/construction/) - [Government & Municipal Facilities](https://nimbio.com/solutions/government-municipal/) - [Integrators, Gate & Low-Voltage Techs](https://nimbio.com/solutions/integrators/) - [Gate Access for People with Disabilities](https://nimbio.com/solutions/residents-with-disabilities/) - [How Do Delivery Drivers Get Into Gated Communities?](https://nimbio.com/delivery-driver-gate-access/) ## Developers - [Nimbio Developers](https://nimbio.com/developers/): REST API and SDKs for building custom integrations (fleet routing, self-storage/property management, parking and mobility apps). - [API reference (api.nimbio.com/llms.txt)](https://api.nimbio.com/llms.txt): full API/SDK documentation map for the developer portal. ## Support - [FAQ](https://nimbio.com/faq/) - [Help](https://nimbio.com/help/) - [Installation Guide](https://nimbio.com/install/): independent professional gate/low-voltage technician installation is recommended. - [GuestView Guide for Residents](https://nimbio.com/features/guestview/residents/) - [GuestView Guide for Community Managers](https://nimbio.com/features/guestview/managers/) - [GuestView Guide for Guests](https://nimbio.com/features/guestview/guests/) ## Company - [About Nimbio](https://nimbio.com/about/) - [Testimonials](https://nimbio.com/testimonials/) - [Contact Us](https://nimbio.com/contact-us/) ## Optional - [Shop](https://nimbio.com/shop/): Nimbio hardware controller, sold direct. - [Blog](https://nimbio.com/blog/) - [Changelog and Release Notes](https://nimbio.com/changelog-and-release-notes/)
