Recording Time 
The recording time of the TR9 DVR depends on: 
•  Disk drive capacity 
•  Recording speed 
•  Image quality/compression setting 
•  Image content, motion and lighting 
When more than one camera is connected to the TR9 DVR, the recording speed (IPS) 
for each camera is calculated by dividing the selected recording speed by the number of 
cameras. For example, for a recording speed of 60 images per second and three 
cameras, each camera will record 20 images per second. 
  NOTE: The recording times shown below are based on typical image content, 
motion and lighting conditions. Your recording times may vary.
