Chronos User Discussion / Long-term sustained capture (1TB of data) to SB or and network?
« on: April 20, 2022, 06:21:38 AM »
We have a pair of 2.1 camera and have used them very successfully for one project -- but we had short clips downloaded vis SD cards since at that location we did not have network.
We are thinking of using them on a new project that would require a small window (maybe 128x128 image) captured as fast as we can.. but need to capture for a moderately long term (8hrs a day for 50 days). 8hrs at 7500fps of 128x128 is about 1TB but I can download over a network at outside the capture window. I see 2 ways.. capturing to a large SD card in the camera or a USB SSD in the camera (a 1TB class 10 card should hold 8.6 hours) and then remotely access afterward via SMBor streaming over the network interface and capturing on the computer. The streaming view over the network says it supports 1920x1080@60fps but I presume that is H264 and I need uncompressed. Looking through manual I did not see any way to stream uncompressed.. anyone find a a way? An alternative would be to save to NSF but have no idea what sustained rate I could do.
Can anyone comment on experience with the tradeoffs between long-time SD capture and long-time network capture? Am what I am describing even possible or I am limited to 32GB of capture then stop recording to dWe have a pair of 2.1 camera and have used them very successfully for one project -- but we had short clips downloaded vis SD cards since at that location we did not have network.

The streaming view over the network says it supports 1920x1080@60fps so at 128x128 the data rate seems like we might get 7500fps at the same effective pixel/data rate.
