Ubiquiti EdgeRouter X SFP vs Ubiquiti EdgeRouter POE?

Question

FreeBSD

Good day.
Please help me choose Ubiquiti EdgeRouter X SFP or Ubiquiti EdgeRouter POE (5 port)?
Both devices support PoE output.
Both have dual core processors.
The plans are to buy 2 identical devices, demolish the native EdgeOS, install FreeBSD / OpenBSD / Linux and use the first one for ACS, and the second one for recording from CCTV cameras (instead of a DVR / server).
Is it possible?
PS
Or try to build everything on Ubiquiti TOUGHSwitchPRO POE (8 ports)?

Answer 1

both support poe. but at one on all ports. and the other on one!

Answer 2

Hmm.
Let's start with the fact that PoE, which Ubnt has, is not 802.3, but we simply drive 24-48 volts over 45-78 paras. And normal ip cameras need 802.3. Theoretically, at 48 volts from ubnt, they will start, but it will be very bad.
And the second part of the plan is even "better".
The video recorder is a specialized device with ready-made firmware and specials. iron with accelerators for encoding and decoding h.264. And on this mips you are going to do it programmatically? Not to mention that there is practically no open source video surveillance software. ZoneMinder can be left out.
Well, similarly, ACS systems are focused on software for Windows.
