how to I set up WIFI and extend the range of my Wireless Security Cameras for my business?

[obeliskzero]

Hello all!
I have these Firstrend Wireless Security Cameras That I want to get set up on our wifi.
(Link: https/www.amazon.com/dp/B077HX91ZN/ref=twister_B07FTJW87J?_encoding=UTF8&th=1)
Currently, the range is terrible, and all they are currently doing is connecting to the NVR itself.
I'm having difficulties with them cutting out, losing signal, etc.
I was wondering if there was a way to connect the cameras to the WiFi so we can have a better range,
Or if there's a way just to improve our range in general?

Some things I should mention is:
*There are parts of the building that are made out of concrete, and other parts made out of wood.
*It is a one floor, somewhat large building (Used to be a bar) that has a TON of walls.
*We are trying to see both the front and the back of the building, as well as inside.

I really hope we can come to a conclusion so we can fix this issue (and so I don't look like a fool, LOL!)

Thank you so much!

This page -- http/www.surveillanceandsecuritycameras.com/firstrend-1080p-security-camera-designed-for-firstrend-1080p-wireless-security-camera-system/ implies that the cameras and NVR do not use standard WIFI. They are proprietary. If that is the case (and I bet it is) you can't extend the wireless range of the cameras.

Okay, so in reality, the WiFi Range Extender won't help? If it's proprietary, is there a way to change that?
In reality, my biggest concern is that we no longer have the box and can't return it, and i'd be solely responsible.
thank you!

I can't find any technical info on the cameras (quick look). If you can find an FCC ID registration number, you can get more technical info about the radios at the FCC page. My guess is that the system uses 900Mhz or some other frequency besides standard WIFI frequencies.
