I recently bought a SD49425XB and managed to get the auto tracking firmware put on this and everything seems to be working perfectly. One thing I thought would be good was to set up auto tracking for my alarms and have my alarm do a tour through my presets in the evening. It seems, however that the "timed task" functionality prevents the auto tracking from working correctly!
I've written a little Python script (that you can run on a server, or your PC) which actually uses the Dahua API to set the presets based on your settings at a specific interval and during specific times of day. This means you retain the auto tracking feature, because it's the same as simply selecting a preset in the web interface.
I've tested this on the SD49425XB, but this should work on ANY Dahua NVR / PTZ.
