We are going to replace our Swann NVR-7250 with eight poe camera with a new system and would like recommendations. I don't mind if the cameras need to be from the same manufacturer as the NVR and I don't mind putting together a system if I can get a better NVR and better cameras not buying a package. I really like that our Swann system doesn't require a monthly fee but I don't like their app. Thanks for suggestions.
