This article seems to not have experience in what what a field tech needs that works on ip cameras
I don't believe security camera switches were well researched on this article or know of what happens in the field for technicians. Yes power is important for the ports but there are additional options/features available on other manufacturers out there which blow some of the ones mentioned out of the water.
I personally have used Netgear, Engenius, TP-Link, Zyxel, etc. & recently have come across Zyxel's GS1300 switches. These switches not only have a good amount of power but they have the ability to power a camera 250 meters away. That's over 800 feet to power an ip camera! We have stumbled across situations where the runs do need to be far from the switch. This happens due to lack of power in the area or even the lack of structures. We recently deployed this switch in a parking lot setting where the run was around 750 feet from the switch. We were able to increase the power of the port to power the camera and boom the camera came up and is still up to this day.
An additional feature for ip camera installers which helps a lot is the ability to reboot the port remotely or even automatically. The Zyxel GS1300 has this ability to either reboot the camera when it drops automatically or you can even connect it to their cloud which gives the ability to view and reboot ports remotely. This is HUGE for ip camera installers and saves the time to drive a truck to the site.
It seems this article only touches on minor features which most switches are already providing today and doesn't understand which a real work ip camera installer goes through or requires.
