Smarter entry solutions for a safer, more efficient site
Protect essential assets with smart IoT monitoring solutions designed for safety, security, and operational continuity.
-
Universal retrofit
Works with existing gates, barriers, doors and intercoms (NO/NC relays, Wiegand, dry-contact). Upgrade without rip-and-replace.
-
Multiple access methods
PIN keypad, QR codes, ANPR, “free-call” from phone, plus Apple CarPlay & Android Auto. Mix and match per site or user group.
-
Cloud management
Grant/revoke access, set schedules and visitor passes in WebAlarm™. Real-time events with searchable audit logs and exports.
-
API integrations
Sync users and bookings via REST API/webhooks for automated access control across car parks and buildings.
Flexible access methods that fit your site
ControlFreq gives you multiple, mix-and-match ways to control entry across car parks, vehicle gates and building doors. Deploy ANPR, QR / Passkey, PIN/keypad, RFID & long-range vehicle tags, or intercom for assisted entry—then manage them all from one place.
Because everything is controller-agnostic and retrofit-ready, you can modernise existing barriers, gates and doors without a rip-and-replace project. Add new entry points, users and schedules in minutes, and keep a full audit trail of who went where, and when.
Instant alerts when it matters
Stay ahead of issues with real-time notifications for access events and exceptions. Get alerted to granted/denied access, forced door, gate left open, tamper, power/battery status, and controller faults—before they turn into downtime.
Choose the channels that work for your team: SMS, email, push, voice calls or integrations with tools like Teams/Slack via. Use escalation rules and time-of-day policies so the right people are notified first time, every time.
Plug-in alerts: Teams, Slack, Telegram
Cloud-based control with 24/7 visibility
With WebAlarm™ Cloud, you can view and manage every entry point across one or many sites—remotely and securely. See live status for car-park lanes, vehicle gates and doors, apply role-based permissions, and make changes instantly without a site visit.
Access comprehensive reporting and event history for audits and compliance, and use APIs to connect with booking platforms or third-party systems. Multi-network 4G/5G connectivity keeps everything online, giving you continuous oversight from anywhere.
