Should I add a Power Injector

[Firefighter]

I'm installing Empire Tech Loyrta 4mp PTZ that uses 22 watts with the IR on
to a Amcrest NVR with a Max 22.5 Watts POE Per Port...

This doesn't follow the general 80% rule in electrical.

Should I install a power injector and not worry about burning up a poe port or am I over thinking it?

Ptz PTZ494M-25X
Nvr Amcrest 4108e

Thanks

i have a 4108 Poe, but i only bench tested a PTZ ( loryta 4mp ) for about a week mostly with IR on as it was in a basement .......So i know it works, ....but long term... no data for you....,
I got a POE switch. because i found it speeds up the access time to the Web GUI's of the cameras when they aren't bound to the NVR,
I sold the Loryta PTZ but You might just as well get an "802.3 at" ( 30 watts per port) rated poe switch. Like a 4 port....it's a bit cleaner on the other end of the wire run if you don't have to monkey with an injector on the other end of the run....
if it's on a fairly short run the voltage drop would be minimal....but if its on a really long run...the Amcrest might under power it....unless the Loryta has some +/- variance allowed.

Thanks, I bought a 30 watt injector since this is a clients house and not my own..
