This! I manage about 70 CCTV cameras, over the past 15 years. Partially as a hobby. and axis cameras are the best bar none. They are expensive, but if you don’t have a need for the latest gen axis, then eBay is your friend, along with one or two generation prior of axis current gen cams. They are just very well thought out in terms of installation, and ui/operation. Axis is among the most responsive to security issues (which mostly can be negated by controlling your cameras at the network level through vlans and firewall rules). They have a very intuitive web based UI, for example one well thought out ability is through events/rules- you can add a physical SD card into the camera and set up a rule that if the video feed is not being accessed ( set a inverse trigger for “live stream accessed”) then start recording to the on-cam SD card (i.e. your NVR has gone off-line or a network issue is stopping the feed, then you have onboard storage saving that video). That’s just one example.
