Battery-free, keyless locking for the access points that matter most.
Cabinets, manholes, gates, containers and security doors can be managed without physical-key handovers, with every authorised opening visible on the VIoT platform.
Smart Infra Locks
Battery-free, keyless locking for the access points that matter most - cabinets, manholes, gates, containers, and security doors across critical infrastructure sites. Every access is logged, authorised remotely, and visible on the VIoT platform, so site teams stop depending on physical keys and start managing access the way they manage every other asset.
Smart Infra Locks
Battery-free, keyless locking for the access points that matter most — cabinets, manholes, gates, containers, and security doors across critical infrastructure sites. Every access is logged, authorised remotely, and visible on the VIoT platform, so site teams stop depending on physical keys and start managing access the way they manage every other asset.
Battery-free locking - no batteries, wiring, or recurring replacement; the lock draws its energy from the key device at the moment of opening
Remote, revocable access - grant or cancel access instantly from the platform; no physical key ever needs to be collected back
One-time, auditable access codes - every opening uses a fresh credential, so a lost key device or code carries no standing risk
Works through outages - stays operational even if mobile network or site power fails
Built for harsh sites - rated for extreme heat, cold, moisture, and vandalism; suited to outdoor and unmanned locations
Centralised management - manage locks, sites, and user access on-premise or via a secure cloud, with a full access log for every door
An authorised user requests access through a mobile key device or an app, which is issued a fresh, single-use credential tied to that one opening - nothing is stored on the lock itself. The lock reports every open/close event, along with tamper and battery-health alerts from its connected door/sensor guard, back to the VIoT platform over the site's available network. On the platform, teams see live lock status, a complete access log (who opened which lock, when), and instant alerts for forced entry, sabotage, or a door left open.
