Buying access control software is not only “which controller”. Decide where data lives, whether video shares the same UI, how door growth is priced, and how fast guards can resolve an incident.
1. On-premises vs cloud
Factories, government, and large offices increasingly need offline operation and data inside the organization boundary. Cloud is easy to start, but ties you to connectivity and subscription. See ACS without the cloud.
2. Hardware and drivers
If the site already has ZKTeco C3, pick software with a native driver — not a custom script per integrator. EAS supports C3 out of the box — see the access control module.
3. ACS + video + map
A separate VMS and ACS doubles windows at the post. Platforms like EAS link door, event, and camera on a facility map.
4. License and TCO
Count more than the entry price: per-door fees × 12 months often beat a one-time license. EAS is ₽30,000 with no door limit; see pricing.
5. Erst testen, dann kaufen
Unterschreiben Sie keinen Vertrag, bevor Sie sehen, dass es bei Ihnen funktioniert. Installieren Sie EAS auf Ihrem Server und öffnen Sie eine echte Tür mit Ihrem Controller. Dafür gibt es die kostenlose 30-Tage-Testversion; die Oberfläche können Sie zuerst in der Browser-Demo ansehen.
