How many pictures per second (PPS) can the DX-TL910U record?
a. The DX-TL910U can record up to 60pps. When only one channel is used, the DVR can record 30 PPS, when more than one channel is being used the DVR can record up to 60pps. The unit is intelligent and it does its own math calculating the most allowed PPS. Using the available overall 60pps and the number of cameras connected the DVR will assign the maximum allowed PPS per channel. For example if 6 cameras are being used (6 is divided into 60 PPS) giving a maximum 10 PPS per channel allowed. This number can be changed down to 4, 3. (lowered but not raised above the max of 10).
