DJF 4.0 Canon PTZ - User Guide 

Thanks. A dedicated windows/ Mac computer for Companion app must be on 24/7 to control Canon Cameras this way all the time.

Hello I am using CANON CR-N300 / CR-N500 as a Companion. I recently upgraded the firmware and the speed control for ZOOM In / ZOOM OUT in Companion is not working. It zooms in/out very slowly. I would appreciate it if you could improve it. For reference, when I asked CANON, they said that the CR-N300 & N500 firmware cannot be updated to the previous version. I tried to update the firmware to the previous version, but it didn't work. ㅠㅠ Latest version V150 / Previous version V140 For reference, the latest version only has the basic function of autotracking, which is inconvenient. ㅎㅎ (Full version is $1,200) Presets and other functions work normally. Thank you. Companion 3.3.1 /canon v1.5.0 /CR-N300/ CR-N500
