I found a great deal on these cameras... I think... about $60 each, so I wanted to buy a couple to add to my Blue Iris NVR; however, I quickly learned from reading that Swann likes to lock their cameras for use only with their NVR... That being said I understand that this may actually be a re-branded HKvisionand it may be possible to install HKvision firmware or otherwise get these to work in another ecosystem.. Is this just a waste of time?? Any help is appreciated.. (I have not purchased one of these yet)
