Help IP cameras conflicting

[Mornedb]

I recently bought 5 ezviz husky cameras and a 8ch nvr. I installed 4 cameras and everything was going smoothly until the last camera. As I connected it to the ezviz app, one of the other cameras went offline. I could not get it to work until I took if off and reset it and re-added it to the app. As I did that then another camera went offline. So I can't have all 5 running at the same time? Is there an ip clash? I assigned them all ip address to each of the mac addresses but didn't change anything. Can only get 4 working at one time. What can I do? They are connected to a 8 port switch with ethernet cables. Help would be really appreciated.

Hi,
Sorry, we have no recent experience with EZVIZ - does Hikvision's SADP (or is there a similar EZVIZ utility?) show the cameras on your network, connected to your switch.
I can't think of any reason why you would not be able to add / get more than four working.
