Problems This Solves
Mechanical keys were not designed for infrastructure at scale
Hundreds of ODB points, distribution panels, and switchgear units are spread across the field but are still managed using physical keys. This is where the problems begin.
Complex key management
Hundreds of keys for hundreds of assets can easily be lost, are expensive to duplicate, and are difficult to retrieve when technicians change or vendor contracts end.
Uncontrolled authorization
Anyone holding the key can gain access. There is no control over who may access a specific location or during which time period.
No audit trail
When cable theft, vandalism, or operational negligence occurs, there is no record showing who last accessed the asset or when it happened.
High maintenance burden
Conventional electronic locks require cable installation or routine battery replacement, which is impractical for thousands of distributed infrastructure points.
Core Product Functions
One integrated system: passive padlock + smart digital key
The CAA passive padlock requires no battery or wiring. All power and access credentials are transferred from the digital key upon contact. Low-power IoT technology and digital encryption ensure that only authorized personnel can unlock the asset.
