A:Answer Hello Josh,
Thank you for reaching out to us with your question. Yes, this recorder can be upgraded to at most a 4 TB hard drive. There are many variables that contribute to the overall amount of storage space. Frame rate, recording resolution, number of cameras, area activity, and PIR settings will all play a factor. Contact our technical support team and see if a rough estimate is available.
Please let us know how we may further assist you,
Thank you.
