Gate and Access Control App Development

What a gate and access app has to get right

Access control is a chain: a person, a credential, a decision and a physical action at a gate, door or barrier arm. The app sits in the middle of that chain. It must know who the person is, whether their credential is valid for this gate at this hour, and how to send the command to a controller that may be on cellular, Wi-Fi or nothing at all. Tepia starts every access project by drawing that chain for each site type you serve, because a gated neighborhood, a self storage facility and a truck yard make the decision differently.

Guests are the hard part. Residents want to let in a dog walker every weekday morning, a contractor for two weeks, a party of twenty on Saturday and a delivery driver once. Managers want each of those passes to expire, to be traceable to the resident who issued it, and to stop working the moment a resident moves out. Couriers and emergency services need their own paths that do not depend on a resident answering the phone.

Safety is not optional. Automatic gate operators are built to the UL 325 safety standard for entrapment protection, and an app must never bypass sensors or encourage someone to open a gate they cannot see. Tepia designs remote open features with clear warnings, optional proximity limits and logs, and leaves safety logic in the operator where it belongs.

Credential types and when to use them

Most sites end up with several credentials at once. Tepia helps you choose which ones the app issues and manages:

The app’s job is to manage all of these from one admin portal, so issuing a new resident’s tag, plate, app access and PIN happens in one step and revoking them happens in one step too. Our Bluetooth and BLE app development page covers the proximity side in more depth.

Hardware, cloud and property system integrations

Tepia builds access apps across three layers. On the device, the app handles login, credentials, Bluetooth and push notifications, usually in native Swift and Kotlin or React Native with native modules for Bluetooth. In the cloud, a backend on AWS or Azure holds sites, gates, users, schedules and logs, and sends signed, short lived commands. At the gate, controllers receive those commands over cellular or the site network and report status back.

• Controller firmware and protocols from your hardware team, including relay outputs, Wiegand or OSDP readers and over the air updates.
• Property management systems such as Yardi, RealPage or AppFolio, so move ins create access and move outs remove it.
• Self storage management software, so a tenant who falls behind loses gate access automatically and regains it when the account is current.
• Twilio for call box calls to residents’ phones and text guest passes.
• Video systems that attach a snapshot to each entry when cameras are present.

Security gets the same weight as the user experience: device binding, rate limits on commands, encrypted traffic, role based admin rights and penetration testing before launch. Tepia’s IoT and connected device team handles provisioning so each controller is enrolled once and trusted from then on.

How Tepia approaches gate and access control apps

Tepia runs its six phase process with a US based project manager who coordinates your software, hardware and installer teams, so firmware and app releases line up.

1. Discovery: site visits to representative gates, interviews with residents, property managers, installers and support staff, and a review of controller capabilities and existing apps. Deliverables are an Investigation Summary, an Interview Summary and User Stories such as a resident sending a one day pass to a contractor from the driveway.
2. Design: a design questionnaire, moodboards, a style guide, and wireframes for the resident home screen, guest pass flow and the manager portal, tested with residents who are not technical.
3. Development and Testing: an Alpha at a lab bench with real controllers and a Beta at live sites, with test plans for command latency, offline Bluetooth fallback, pass expiry, permission edge cases and security.
4. Training: hands on sessions for property managers and installers, plus a support playbook built on scenarios like a resident locked out at night.
5. Launch: import of sites, gates and residents from spreadsheets or the old system, a site by site transition, and support reps ready for the first weekend.
6. Support: quick response on access failures, bug tracking, and feature requests such as new controller models or plate recognition.

Typically Discovery takes 1 to 3 months, development and QA 2 to 6 months, and launch about a month, with hardware schedules setting some milestones. Read more about our process.

Off the shelf access platforms or your own app

A property manager with a few gates can often use an access platform sold with the hardware, and Tepia will say so in Discovery. Building your own app makes sense when:

• You manufacture gate operators, controllers or call boxes and want an app and portal under your own brand.
• You are a dealer or installer managing hundreds of sites and need one portal across them.
• Your sites mix gates, doors, amenities and elevators from different makers and need one resident credential.
• Your access rules depend on account status in a property or storage system the platform does not support.
• You need guest, courier and vendor workflows that the packaged app handles poorly.
