Hi I`m going to upgrade to a NetGear 16P POE+ GB Unmanaged switch from an unnamed 8 port one I got from Andy to add a few more cameras.Is there a Wiki page ,or a step by step about this procedure?I`m sure its not as easy as it seems from reading here for years. I couldn`t find any. I was thinking about putting 3 newer models in place of the older ones before adding more,. Can I change the IP of the new camera to the older one after unplugging it and just switch cams? They are not PTZs. Although 2 are the newt 8K dual 4MP color model.I hope someone can point to information or give me an idea how to do this. Seems fairly simple ,but my first time.Have to be careful! Thanks for any comments.
