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. 구매 전에 먼저 써보세요
현장에서 동작하는 것을 확인하기 전에는 계약하지 마세요. 자기 서버에 EAS를 설치하고 자기 컨트롤러로 실제 문을 열어보세요. 이를 위한 무료 30일 체험이 있고, 화면은 먼저 브라우저 데모에서 볼 수 있습니다.
