<\/span>What is the difference between Basic mode and Cloud mode?<\/span><\/summary>

In Basic mode, you can program one controller with a connected code keyboard through that same code keyboard (or manage it through the app – with wifi). The controller does not require an internet connection. Basic mode is suitable for installations where there are only a few users and a maximum of two gates\/doors. Adjusting codes is not often done, so management is optional rather than required. To manage via the app, you must be within wifi range of the controller. <\/p>\n

In Cloud mode, you can install multiple controllers with and without a code keyboard. The controllers require an Internet connection. Cloud mode is suitable for installations where there are multiple users and multiple doors. Where there is a need for timetables, automatic switching user groups. Adjusting user rights is done regularly and easy management is an essential part of the installation. <\/p>\n<\/div><\/details>

<\/span>What is an ES4 controller?<\/span><\/summary>

The ES4 controller is the heart of any setup.<\/p>\n

A smart piece of hardware – 100% developed and produced in Belgium – that allows you to achieve small, simple installations (Basic mode) or larger more complex installations (Cloud mode).<\/p>\n

You can group controllers into single or multiple installations. You can manage access with or without a keypad and have the flexibility to securely access any application up to 500 users with the same controller. <\/p>\n

The device functions without internet, as well as over wifi, LTE-M \/ 4G and Ethernet (RJ45). So it can also be easily installed in locations that are mobile (e.g., yard chains, events). <\/p>\n<\/div><\/details>
