Blue Iris

I have two Amcrest cameras that receives a clip: write error 80004005, undefined error. The third camera is running fine. The cameras are set to continuous recording. The file rotates to a new file name when the error occurs. Any suggestions on how to fix this?

Do all of the cameras write to the same location, is it a local drive or on a NAS or other remote drive, do all of the cameras have unique short names? How much free space is available. Are you recording to the standard BVR format? What is the memory that is available, what is the CPU load? Is this an actual PC or is it running on some sort of Virtual Machine? How is your storage configured to manage free space? How often does this error occur? Is the folder excluded from being scanned/monitored by your AV software

Good questions. A web search for this error shows:

Error Code 0x80004005 occurs when Windows cannot access a file or folder, and has several potential causes such as ownership issues, an antivirus blocking access, network configuration errors, or a bugged Windows Update.
