Hardware-free, self-service entry for unmanned gates and entrances.

How It Works

How Sentry Solo Access Control Works

No callboxes. No keypads. No fobs. No hardware to install or maintain. Residents enter with their phone — visitors scan a QR code.

Residents

VirtualKey Smartphone Entry

Residents open gates, doors, and amenity entrances with one tap in the app — no fobs, remotes, or codes to carry. They manage their own visitor list and get arrival notifications from the same place.

SentrySign & VirtualKeypad QR Entry

Visitors scan the posted SentrySign QR code with their phone camera. A digital keypad opens right in their browser to enter a temporary code — no app download, no callbox, no waiting.

Features

Sentry Solo Access Control Software Features

Sentry Solo comes in three deployment options — VirtualKey for resident entry, VirtualKeypad for visitor access, or a hybrid that combines both. Every option includes a cloud-based admin dashboard with real-time entry logs and reporting.

Option 1 · Resident Entry Only

VirtualKey Smartphone Access

VirtualKey turns every resident's smartphone into their access credential. One tap opens any authorized gate, door, or amenity entrance — no fobs, remotes, or codes to manage.

Residents stop carrying fobs, remotes, and gate codes.
  • One-tap entry: Residents open gates and doors instantly from the mobile app.
  • Replaces fobs and remotes: Encrypted mobile credentials eliminate physical hardware.
  • Personal entry log: Residents see a history of their own access activity.
  • Simple by design: Secure personal access without visitor-management features.

Option 2 · Visitor Access Only

VirtualKeypad QR Code Entry

VirtualKeypad replaces callboxes, keypads, and kiosks with a QR code sign at the entrance. Visitors scan the SentrySign with their phone camera, enter a temporary code in their browser, and the gate opens.

Visitors get in with a phone camera — nothing to download.
  • QR self-service: Visitors scan the SentrySign to open the VirtualKeypad in their browser.
  • No app required: Works on any smartphone with a camera — nothing to install.
  • Temporary access codes: Codes are issued per visit and expire automatically after use.
  • Zero hardware: Eliminates callboxes, keypads, phone lines, and repair costs.

Option 3 · Complete Access Control

Hybrid: Resident Entry + Visitor Management

The most complete self-service option. Residents get VirtualKey for personal entry plus the ability to manage their own visitor list, send digital access codes, and receive arrival notifications — all from one app.

One app for resident entry and the guests they invite.
  • Full access control: Residents enter with VirtualKey and manage visitors from one app.
  • Visitor list management: Authorize guests and vendors directly from the mobile app.
  • Arrival notifications: Get real-time alerts when a visitor scans the SentrySign and enters.
  • One platform: A seamless experience for residents and visitors across every access point.

The Control Center

Sentry Solo Admin Dashboard

Every Sentry Solo deployment includes a cloud-based admin dashboard that gives property managers full visibility into access activity, user management, and reporting across all entry points.

Grant or revoke any door from anywhere, instantly.
  • Access restrictions per household: Define a restriction — like limiting certain gates or amenities — then assign which households it applies to and when. Your access points, your rules.
  • Access point scheduler: Automate amenity doors and unmanned gates with flexible open/close times, and set separate schedules for residents, guests, or vendors.
  • Real-time entry logs: View every VirtualKey and VirtualKeypad entry as it happens.
  • Instant credentialing: Grant or revoke resident access immediately from any device.
  • Reporting & audit trails: Generate detailed entry reports for security reviews and compliance.

Why Communities Switch

Sentry Solo vs. Callboxes, Keypads & Fobs

Traditional gate hardware breaks, gets shared, and costs money to maintain. Here's how hardware-free Sentry Solo compares to the callboxes, keypads, and fobs it replaces.

Sentry Solo Callboxes, Keypads & Fobs
Hardware to install None — software only, works with your existing gates Physical units to purchase, wire, and mount
Repairs & upkeep Nothing to break — no weather, wiring, or vandalism repairs Ongoing repair bills for weather, wear, and tampering
Visitor access Each visitor gets their own unique code that expires automatically One shared code everyone eventually knows
Resident credential The phone residents already carry Fobs and remotes that get lost, cloned, or passed around
Updating access Grant or revoke instantly from the dashboard Re-key locks or reprogram and replace fobs
App for visitors None — visitors scan a QR code and use their browser Some systems require an app download or a phone call
Entry records Searchable digital log of every entry Little or no record of who came and went

Comparison reflects common limitations of traditional callbox, keypad, and fob-based gate access.

FAQ

Common Questions About Sentry Solo

Do visitors need to download an app?
No. Visitors scan the posted SentrySign QR code with their phone's camera, and the VirtualKeypad opens right in their browser to enter a temporary code. There's nothing to download or install.
Do we need to install any hardware?
No. Sentry Solo is software — it works with your existing gates and entrances. It replaces callboxes, keypads, and fob readers, so there's no equipment to buy, wire, or maintain.
How is Sentry Solo different from a callbox or keypad?
A callbox or keypad is fixed hardware that relies on one shared code and needs ongoing repairs. Sentry Solo gives residents one-tap entry from their phone and issues each visitor a unique code that expires automatically — with a searchable digital log of every entry and nothing to break or re-key.
Can residents send their own guest codes, or only administrators?
Residents can. When a resident adds a visitor, that guest automatically receives their own access code — which they can save to Apple Wallet or Google Wallet for a fast, tap-to-enter arrival. Administrators can manage and revoke access too, but residents don't have to wait on the office to invite a guest.
Does Sentry Solo work for amenities, not just the main gate?
Yes. Sentry Solo controls access to pools, gyms, clubhouses, and other amenity doors as well as gates and entrances — each with its own access rules and schedule. You can manage every access point on the property from one dashboard.
What happens during a power or internet outage?
Sentry Solo can continue operating offline, so access keeps working even when the connection drops, and activity syncs back to the dashboard once service returns.
What kind of gates and entry systems does it work with?
Sentry Solo is software, so it integrates with your existing gates and entry systems — there's no need to tear out or replace your current setup. It layers smartphone and QR-code access on top of the gates you already have.
How long does it take to set up Sentry Solo?
Most properties are up and running in about 30 days. Our team configures your access points and rules, sets up resident accounts, and gets your gates and amenities live — no hardware installation to schedule.
Can we use Sentry Solo together with Gate Sentry?
Yes. Many properties run both — Gate Sentry at the staffed main gate and Sentry Solo at unmanned secondary gates, amenities, and back entrances. Both run on one platform, so residents use a single app and every entry appears in the same log.
