Interlock Mercury G3 Smart Gate Lock with Dual Camera Security

The Interlock Mercury G3 is best suited for homeowners who want a smart gate lock with stronger gate visibility, visitor awareness, parcel monitoring, and remote app access. It is designed for Singapore metal gate setups, including common HDB, condominium, and landed property gates.

The upper camera helps you view visitors at face level, while the lower camera helps you monitor parcels, items, or movement near the floor area. This is useful because many gate activities happen at different heights, especially for deliveries.
