Hello, y'all！

Today we are going to answer a question that many of you are concerned about - can the surveillance system run without network?

In fact, none of our DVR/PoE NVR system require an internet connection to be used locally. The internet connection is used to allow remote connection using a smartphone app or PC client. Non-local operation is limited when there is no internet connection, but the system will still work as a local security system with recording and storage. 

After understanding this, a new question arises: some Zosi products are not sold with a hard drive, so how do we pick the right one to install and use on our own?

In general, I recommend that you choose a professional surveillance internal hard drive instead of a regular PC hard drive, as they differ greatly in terms of read/write and storage parameters. For example, a 3.5 inch Seagate Skyhawk, Samsung or Western Digital (purple) hard drive is perfect and compatible with Zosi products, so it's a good idea to buy them.

As for how to install and format the drive to make sure it works, I'll tell you more about that in another article later. 

Please let me know if you have any questions!
