Configuring the DVR
700-0042 R004 3–11
If all the cameras are configured to record at the same resolution, frame rate and
picture quality, calculate the system recording capacity by dividing the value in
the table by the number of cameras. If the cameras are set to record at different
rates, contact Seon Design for assistance in calculating the recording capacity.
The EX4 DVR processes 4 different video inputs simultaneously — the frames
per second (FPS) is aggregate based on the sum of all the camera frame rates. In
other words, the recording times shown in Table 3-6 to Table 3-9 are independent
of how many cameras are connected to the DVR.
Important:
The average image size is dependent on the scene content and the lighting
conditions. Your actual recording times may vary.
