Whatever CCTV system one chooses it will always need cameras, so a camera is a no brainer first purchase, assuming that one would opt for a ONVIF compliant system. One can then test this using Blue Iris or similar and a spare PC. However, in order to choose an appropriate camera one needs to understand how motion detection works. Is it done by the NVR or by the camera, or a combination of both?For example, a camera could have a PIR built in, whereas the NVR can only “see” the image. In this connection, I recall that somewhere in your articles you said that your system did not support advanced motion detection, whereas in your packaged systems review you put this as a con. Thanks for stopping by!Yes I am familiar with Swann equipment and they have lots of good features. However the reason I do not recommend them is that their cameras and NVRs are locked down – they do not work with any other brand or manufacturer’s products. You can see under the compatible products section of the product page, they list only a few Swann NVRs. This is because they do not support the ONVIF standard which guarantees inter operability. Or in other words you are stuck with them once you start buying their cameras/NVRs similar to what Apple does with iOS. This is not at all the DIY spirit I subscribe to, so I avoid such brands.
