Good morning, I have an NVR2116HS - 4KS3 and I am adding a channel from an XVR4108HS, it is added without problems but I cannot use the SMD function, when activating it on that channel it gives me this message: the maximum threshold of the device analysis channel has been exceeded. I don't understand it. I only have that active channel of the 16 that the NVR supports, according to the characteristics the NVR supports AI (smd), thanks
