Description
Gate security in Singapore homes often faces unique challenges compared to main door security. Unlike interior doors, gates are exposed to corridors, visitors, and delivery activity — making visibility just as important as access control. The Interlock Mercury G3 Digital Gate Lock redefines that balance with a new layer of awareness built directly into your gate.
First Dual Camera Smart Gate Lock in Singapore
As the first dual camera smart gate lock in Singapore, the Mercury G3 introduces upper and lower camera monitoring engineered specifically for gate environments. The upper camera provides clear visual verification of visitors at eye level, helping homeowners confirm who is at their entrance before granting access. The lower camera monitors the floor area, detecting parcels, items, or unusual activity that would typically go unseen by a conventional lock.
This dual-camera system transforms your gate into an intelligent observation point — capturing everyday moments as well as potential security events. Whether you live in an HDB flat with a corridor gate, a condominium hallway unit, or a landed property with frequent gate movement, the Mercury G3 enhances your home’s situational awareness without relying on external cameras.
Built upon the trusted foundation of the Mercury G2, the G3 represents a major evolution in smart gate protection rather than just an update. It maintains the familiar access convenience (palm vein, facial recognition etc.) Interlock users trust while adding a deeper sense of peace — knowing that your gate now watches just as carefully as it locks.
