The outcome you are buying
Every entry starts with a conversation you control — from the doorway, the app, or wherever you are.

Opening without knowing
Gates opened blindly defeat access control entirely.
Visitors stranded at the gate
Failed intercoms create frustration and improvised access.
No record of entries
Buzz-in without logging weakens accountability.
Audio-only ambiguity
Video confirmation removes doubt about who is at the gate.

Common questions
Should I choose audio or video intercom?
Video adds identity confirmation at the entrance — valuable for homes, estates and receptions. We recommend based on entrance type, budget and risk.
Can I answer the gate from my phone?
Where the selected system supports it, yes. Remote answering is confirmed per system during specification.
Can the intercom open my existing gate motor?
In most cases yes — intercom release outputs commonly integrate with existing gate automation. Compatibility is confirmed on site.
My intercom has no sound/video — can it be fixed?
Often. Cabling, handsets, cameras and release mechanisms are all diagnosable — maintenance covers intercom faults.
