Six Key Door Entry Features
Keyless & Mobile Credential Entry
Ditch traditional keys and embrace smart entry: access by mobile app, proximity token or key-fob. Our next-gen authentication methods give you secure convenience, reduce lost key risks and allow instant revocation of access when needed. Ideal for modern premises, these systems bring flexibility without compromising safety.
High-Definition Video & Audio Intercom
See who’s at your door in crisp HD, hear them clearly and speak back instantly — from the door panel or your mobile device. Our door-entry intercom systems combine high-resolution cameras, smart low-light sensors and two-way audio to safeguard your entrance. Whether you’re onsite or away, this feature gives you full control of access with clarity you can trust.
Remote Access & Mobile Secure Entry
Grant or deny entry from anywhere, at any time — with secure mobile and tablet access. Our systems integrate with your smartphone so you can unlock the door, view live video or review visitor logs on the go. Perfect for busy businesses or property managers, this seamless remote control adds convenience and strengthens safety at the same time.
Vandal-Resistant, Weather-Protected Hardware
Our robust entry panels are built to last under the toughest conditions — from extreme weather to high-traffic use. With reinforced metal housings, tamper alert sensors and corrosion-proof finishes, you’ll enjoy reliable performance and minimal downtime. Choose equipment that’s engineered for endurance, not just appearance.
Integrated Access Control & Visitor Management
Turn your door entry system into a full access-control platform: link in fob and card readers, track authorised users, set timed access zones and manage visitor permissions. With our scalable solution you can customise who can enter when and where, giving you smarter oversight and better security across your site.
