KEL-7L — 7" AI All-in-one PC
The smallest KEL that runs AI on the unit: a 6 TOPS NPU behind a 7 inch 1024×600 touch screen, so face recognition and QR reading happen at a door frame or a machine panel instead of on a server. Same body and cut-out as the KEL-7S, with 4K HDMI and gigabit Ethernet added. Designed and built in Thailand.
- CPU: Quad-core Cortex-A72 + Quad-core Cortex-A53
- NPU: 6 TOPS — AI runs on the unit
- Display: 7" 1024×600 · 4K HDMI out
- I/O: RS232/485/TTL · gigabit Ethernet
- Fanless — no moving parts

What is the KEL-7L used for?
Face Recognition
Recognition at a door frame, decided on the panel with no server round trip
Access Control solutions →QR and Ticketing
A compact check-in point that reads the code and decides locally
Kiosk solutions →Machine Vision
A camera at the station, the check running at 6 TOPS behind a 7 inch screen
Machine Control solutions →Frequently Asked Questions
Is the 6 TOPS NPU the same as on the bigger models?
Yes — the KEL-7L, the KEL-XL and the KEL-21L all run the same 6 TOPS NPU and the same Cortex-A72 + Cortex-A53 CPU, so an application built for one runs on the others. What changes is the screen: 7 inch, 10.1 inch or 21 inch.
Can it switch a door lock directly?
No. The KEL-7L has no access-control relay — it reaches a reader or a door controller over RS232 or RS485. If you want the relay on the panel itself, that is the KEL-7S in the same 7 inch body.
Does 7 inch limit what the AI can do?
No. The NPU, the CPU, the RAM options and the serial ports are the same as the 10.1 inch KEL-XL — the screen size only changes what an operator can read and touch.
