It should work in theory, but some things get finicky when the ssid later doesn’t match the mac address they were set up. It’s not consistent though. So setting them up on router 1, then disconnecting it and turning on a new router with the same SSID sometimes causes devices to spaz out and not want to connect to the new router even though the SSID/pw is the same. I don’t know why, I just know that I have had this issue with some devices…but not all of them.
My suggestion is to set up the devices using the phone’s hotspot as their primary WiFi. Then go set them up in the warehouse and activate the hotspot so that they will connect to Wyze servers and start recording. After they start up and you verify they are recording, you can cut the hotspot and go home. They will continue to record, but will not give you any notifications. When you return to the warehouse, you can activate the hotspot and within a few minutes the cameras should connect to it and allow you to access them and their playback on the SD cards remotely.
Again, there will be no cloud recordings and notifications. Also, remember that the SD card loops. A V2 cam uses an average of just over 9GB for a full 24 hours of recording in HD settings. So if you use a 32GB card, you’re looking at 3.5 days of recording on average (give or take a little depending on a few factors). My 128GB cards hold almost exactly 14 days of recordings. So, if you use a 32GB card and try to check something from a week or 2 ago, it will be long gone, unless you have it set to only record when it senses motion.
Make sure to run some tests first (set it up, drop the hotspot, walk away for a few minutes, come back, turn the hotspot back on, try to reconnect to the cam and verify it’s working as intended. These devices aren’t always 100% consistent with each other. Sometimes one will work the way all the others do and the other doesn’t like it even when all the settings are the exact same. So verify first.
Good luck. Hope that helps.
