Manufacturer overview

Mechanical, electronic or hybrid EVVA access

EVVA covers very different security and administration models. Mechanical platforms such as 4KS, MCS, ICS and Akura 44 use protected key profiles and locking plans. AirKey uses smartphones and online administration, while Xesar is designed for scalable systems with local management. Hybrid components can connect both approaches in one property.

Specification

Choose EVVA around the operating scenario

Not every well-known EVVA product fits every property. Key organization, offline operation, smartphone use and ongoing administration should be compared before selecting a platform.

Administration

AirKey, Xesar and mechanical systems differ significantly in issuing, revoking and operating credentials.

User structure

Permanent residents, changing guests and employees require different access media.

Existing installation

Extensions require an exact check of the current EVVA profile, locking plan and availability.

Choose by situation

Which EVVA direction fits your case?

Start with the problem you need to solve. The product is the result of the check, not the starting assumption.

1

Cleaners and contractors change often.

AirKey is strong when rights must be sent remotely and limited by time.

Compare

EVVA AirKey

Plan emergency entry and the charging model too.

2

We want to stay mechanical and plan for a long service life.

Compare 4KS and Akura 44 based on system complexity and budget.

Compare

4KS vs Akura 44

Do not choose the highest tier by default.

3

Shared rooms need electronics, while apartments stay mechanical.

A hybrid EVVA plan can join both areas with suitable combination credentials.

Compare

Akura 44 with Xesar or AirKey

Define common credentials and door groups early.
