The CTV-CR20 EM G controller worked well for a medium-sized access control project. Installation was straightforward, and the integrated EM-Marin reader responded reliably within the specified 5 to 8 cm range. Storing up to 10,000 keys is ideal for our client’s facility, and output signals integrated smoothly with their existing door hardware. Overall, it fit the application without extra configuration needed.

Installed the CTV-CR20 EM G on a recent project requiring autonomous access control. The integrated EM-Marin card reader worked well with our existing cards, and the 5 to 8 cm reading distance was consistent. Memory capacity for 10,000 keys fits our needs perfectly. Setup was straightforward, and the output signals integrated cleanly with the existing system controls.
