1. Total Frame Rate Supported by GV-DVR / NVR V8.7
The table below lists the total frame rates supported by GV-DVR / NVR V8.7.0.0 for fisheye dewarping based on CPU capacity. The number of frames supported by GV-DVR / NVR is increased when a high-end CPU such as Core i7 is used. Note that fisheye dewarping is only supported on GV-DVR / NVR when using single stream.
The table is based on the following resolutions and frame rates:
For H.264
- 1 MP at 15 fps (1280 x 1200)
- 2 MP at 15 fps (1440 x 1376)
- 3 MP at 15 fps (2048 x 1536)
- 4 MP at 15 fps (2048 x 1944)
- 5 MP at 10 fps (2560 x 1920)
- 8 MP at 25 fps (2896 x 2768)
- 12 MP at 15 fps (4000 x 3000)
- 5 MP at 10 fps (2560 x 1920)
