Hi new to forum and camera's. I bought a 8 channel wireless nvr system from a company called ckk on amazon. As i can tell all these chinese companys use the same nvr operating system. Is there a way to not have the camera's use the nvr's built in wireless subnet and use my local wireless network instead. I can get them to use local network wired but not wireless. O btw I am an IT professional so you don't have to dumb it down for me. would be nice to be able to maybe putty into nvr and either change the subnet range, shut it off or be able to go into camera's and change ip address since it looks to me that they are set statically to nvr wireless subnet or install a custom OS on nvr like you can do on a router. cant find anything on the internet to suggest how to do this.

There probably is a way, but not many here will recommend it. In your case, you would rather use the NVR built-in wifi or you will end up causing problems on your wifi.
In fact, Wifi and cameras do not go together, especially if you want it for security/surveillance.
There are always ways if you don't want to run an ethernet cable.
You need power anyway, so go with a powerline adapter to run the date over your electric lines or use a nano-station.
Maybe you are fine now one day with wifi cams, but one day something will happen. A new device, neighbors microwave, etc.
Cameras connected to Wifi routers (whether wifi or not) are problematic for surveillance cameras because they are always streaming and passing data. And the data demands go up with motion and then you lose signal. A lost packet and it has to resend. It can bring the whole network down if trying to send cameras through a wifi router. At the very least it can slow down your entire system.
Unlike Netflix and other streaming services that buffer a movie, these cameras do not buffer up part of the video, so drop outs are frequent, especially once you start adding distance. You would be amazed how much streaming services buffer - don't believe me, start watching something and unplug your router and watch how much longer you can watch NetFlix before it freezes - mine goes 45 seconds. Now do the same with a camera connected to a router and it is fairly instantaneous (within the latency of the stream itself)...
The same issue applies even with the hard-wired cameras trying to send all this non-buffer video stream through a router. Most consumer grade wifi routers are not designed to pass the constant video stream data of cameras, and since they do not buffer, you get these issues. The consumer routers are just not designed for this kind of traffic, even a GB speed router.
When people come here with camera issues that are slow, not responsive, etc. and in troubleshooting we find out the cameras are going thru a router, once they reluctantly remove the camera from the router, everything clears up and then they mention their Netflix and Zoom meetings are better as well.
So the more cameras you add, the bigger the potential for issues.
Many people unfortunately think wifi cameras are the answer and they are not. People will say what about Ring and Nest - well that is another whole host of issues that we will not discuss here LOL, but they are not streaming 24/7, only when you pull up the app. And then we see all the people come here after that system failed them because their wifi couldn't keep up when the perp came by. For streaming 24/7 to something like an NVR or Blue Iris, forget about it if you want reliability.
This was a great test that SouthernYankee tried and posted about it here:
I did a WIFI test a while back with multiple 2MP cameras each camera was set to VBR, 15 FPS, 15 Iframe, 3072kbs, h.264. Using a WIFI analyzer I selected the least busy channel (1,6,11) on the 2.4 GHZ band and set up a separate access point. With 3 cameras in direct line of sight of the AP about 25 feet away I was able to maintain a reasonable stable network with only intermittent signal drops from the cameras. Added a 4th camera and the network became totally unstable. Also add a lot of motion to the 3 cameras caused some more network instability. More data more instability.
The cameras are nearly continuously transmitting. So any lost packet causes a retry, which cause more traffic, which causes more lost packets.
WIFI does not have a flow control, or a token to transmit. So your devices transmit any time they want, more devices more collisions.
As a side note, it is very easy to jam a WIFI network. WIFI is fine for watching the bird feed but not for home surveillance and security.
The problem is like standing in a room, with multiple people talking to you at the same time about different subjects. You need to answer each person or they repeat the question.
Test do not guess.
For a 802.11G 2.4 GHZ WIFI network the Theoretical Speed is 54Mbps (6.7MBs) real word speed is nearer to 10-29Mbps (1.25-3.6 MBs) for a single channel

Agree ^^^^^, Wifi and surveillance cams don't go together well if you want it to be reliable.
My suggestion, if you still can. Return the system you just purchased and look at something from Hikvision or Dahua.

+1 on both previous posts.
Not to pile on but I believe the wireless signal between the wireless NVR and the wireless cams could be proprietary and/or encrypted.

I'd still recommend returning them ..
"O btw I am an IT professional so you don't have to dumb it down for me "
wifi security cameras tend to be a time sink and issues with reliability .. sort of like attempting to keep windows 98 secure ..
+1 above.
Have someone walk around at night and can you identify them (or a stranger) or is it a blur and soft focus due to wifi not keeping up?
Post a picture of someone walking past the camera at night. Maybe you found a cheap camera that works, but we have yet to see that unless the camera is simply for pet watching.
A wise man here says buy once, cry once.
Many of us went down the path of cheap cams and within a year replaced. I have boxes full of junk. I should have just bit the bullet the first time lol.
That is basically what we are trying to share with you.
It is easy to get wowed with a static image from a cheap cam, but clean capture of motion at night is what most of us need. And if a camera can do that, it can do the daytime.

Known around here
I have 1 box of cameras and DVR’s that were part of the learning curve. most analog, some ip.
costs money to experiment. I learned by doing and watching in here. now i’m a Certified hobbyist.
