    I'm curious about the fan noise as well. My company sells injectors to a lot of customers who are looking for quieter solutions, so I'd be interested to find out what are some quieter PoE switches.

    @giomania @Arjun hello friends!!

    any thoughts on a switch to run Blue Iris with about 20 cameras or so?

    A switch with more ports would be fine too..I prefer to have at least 24 ports or more

    I heard Cisco is the way to go, but that may be too expensive? Any alternatives?

    Thank you

    @theoxonian may want to refer to the 24-port V7 switch that @jrf introduced :)

    Also, is there a PoE switch (extender) that is powered fully by PoE, but also contains an AC adapter (which can be plugged into a nearby outlet) that acts as a fail-safe in case that part of the network goes down? The D Link doesn't come with an AC adapter, nor does it support it.

    In essence, is there a switch that can powered by both AC Adapter (connected to AC port) and PoE connected to uplink?

    Seems like the Intellinet 561082, netis PE6105, both come with an AC Adapter, but can be powered by another PoE+ switch as an alternative; but I'm not sure if it can be powered by both at the same time.

    This PoE Switch would be within close proximity to the NVR and act as the bridge between the main switch and the NVR. Thus, a few key cameras (especially in chokepoint areas) would be connected to this switch.

    @Tyler Andrews does this switch support that feature?

    There is a switch a posted a few posts back the "Intellinet" it can do BOTH as in be powered off the uplink port FROM a Poe switch and also provided POE power. It also has the option to add an AC adapter to power it from a wall outlet. However I'm not sure what you are looking for because if the main switch powering it goes down. Even if a remote switch has power are you just hoping to continue recording to SD card? Because you won't have any traffic flowing back to a NVR or such. At that point just put a UPS on the main switch.

    I just feel that redundancy in any setup matters :) Suppose the electrical outlet goes bad switch would fall over to PoE uplink port as backup for source of power; if PoE uplink port fails for whatever reason, switch would still be powered by included AC adapter. Now this is from a power perspective and would still be able to continue feeding video transmission into network through an alternate port (good if its multi-port switch).

    From a data transmission perspective, I'd have this switch connected to another switch (which doesn't have to be a PoE) to continue feeding video into the network without any IP clash.

    It can sound twisted and jumbled, but I wouldn't want to try if this could potentially damage the circuitry in the cameras. I hear PoE is a fairly sensitive thing especially if not handled responsibly, lol :D

    Just ordered #2. Apparently I have WAY too many wired devices in my lan and adding all these cameras isn't helping. I know I'm slacking on the video for the switch. I'm working on it.

    Since you just ordered #2, now I'm even more curious and interested in the sound, lol ;)

    I personally haven't used this particular switch (a customer was showing it to me the other day which is why I recalled it), so I wouldn't want to say 100% it will. But I'm 99% certain it will for two reasons: 1) it has a DC barrel port and 2) based on my experience with other RouterBoard products. I'll check with a guy I know who uses a lot of these.

    However, I can say 100% our passive PoE switch will do 30 watts through the uplink port and have a back-up power supply through the DC barrel port. Full disclosure, this switch is sold by my company and it is Passive, so it doesn't do auto negotiation for the PoE power. Having said that, the other pros are that it's fanless and energy efficient. WS-GPOES-8-7

    I also ran across a different Extender Hub that isn't backed up with DC power, but I'm interested to see if anyone has used one of these extenders successfully: http://amzn.to/2jaGy6U (Again, full disclosure, in case you don't recognize the URL type, this is an Amazon Affiliate link, however I'm genuinely interested to see if anyone has used and liked one of these extenders to see if I should recommend this to customers looking for this kind of thing).

    @Arjun. Not an expert but I saw some potential options using "redundant POE injector".

    Hey Tyler, I'm actually using that Extender Hub right now to power two cameras. It doesn't use a power adapter and is solely for use in IP cameras (as disclosed in specifications on Amazon). @nayr shared his review here, 1 to 4 PoE Extender It provides up to 25.5 watts of power. Each port supports PoE devices which are af compliant. However, this extender needs to be connected to an PoE at-type power source in order for it to fully work.

    Also, as per your recommendation from that product listed on your online store, I'd still prefer active-PoE in this setup, and avoid Passive, as I want the flexibility of adding other PoE devices

    I talked to some Mikrotik experts, and, yes, they work on DC power and pass through PoE.

    I heard back from Intellinet regarding the PoE-Powered 5-Port Gigabit Switch with PoE Passthrough ( 561082), they stressed that Power Adapter and PoE (connected to uplink for power) cannot be used at the same time as a power source. That's a bummer. I've heard some users state that Mikrotik units tend to occasionally reset to default factory settings over time, thus not promising. Any other make & model suggestions?
