Wireless IP Pinhole Camera

[CzarBlanco 0]

Hello everyone

 

This is my first post, I have a project for wireless IP cameras and have some doubts which I hope with your help clarify

 

First, the project requires 2 outdoor cameras and 7 Pinhole Hidden Camera, all must be WIFI and they will be spread over 3 floors.

 

I researched on the subject and these are my questions:

 

• 1. Is there any way to connect them all at NVR, the question is because in the market there are solutions that support only 4 channels.
  2. Should I use 2 NVR to avoid saturating the bandwidth using subnets
  3. Know of any free software that allows me to replace the NVR with a computer
  4. The Pinhole cameras that I plan to use are like this
