Here is my hardware:

Core switch

Nortel (Now Avaya) 5520-24T-PWR POE gigabit switch

Plan

After learning how to configure the nortel switch (should be pretty easy, read up on the manual already), I think the Swann cameras should be plug and play in regards to POE. They work fine using the NVR that came with them which has a 6 port POE switch built in.

However, the indoor Zyxel's are another story, they are not natively POE, and take a 12V/2A DC power source. So my plan is to inject POE into the cables going to them with the Nortel switch, and use a POE splitter at the far end by the camera to extract said DC voltage.

My unknown is that i dont know if 12V/2A will be extractable with a passive POE splitter like the one linked. Thats a pretty hefty load (because the cameras have PTZ and IR on em).

Guidance on if my plan will work?
 
You won't be able to use PoE from the switch to power your non-PoE cameras even with the adapter. You'll need to use the power supplies provided with them and use both parts of the passive setup.
 
and why not? Thats the old cisco way before there were standards and stuff wasnt poe prior to 801.af. Dumb POE basically
 
PoE provides 48V and your device requires 12V. Not going to work with a passive adapter. Cisco had their own proprietary stuff back then.
 
shoot, i hate to have to use the doubleended passive splitters and plug them in in the closet. Thats a huge waste of power space and its an ugly solution
 
What you normally do in enterprise class installs is run Siamese cable which has either cat5e or RG in one sheath and another one with a pair of 18awg power wires. Then you would have a power supply box which you power all of the cameras.

Something like this might work:

1000' 18/2 Fire Alarm cable

The only thing I'm not too sure on is you would really need to make sure that the individual ouputs for each channel on that power supply can handle your PTZs. Some of the ones like that might only output .55amps where yours seems to take a lot of juice at 2 amps to run. I do see that company (Avemia) makes a CMSW236 with the same 12V 2A draw so they should make a supply to power them. Could ask them what models support that particular camera.

Most PTZs are not POE because they draw too much power. If you have a POE+ switch some of the newer stuff can be POE only without a separate power supply.

i havent snaked the ethernet yet either, so its no problem to snake another cable with it, i just hate to run more than is necessary. It bugs me for some unexplainable reason

that switch actually is POE+, it isnt certified for the standard, but it can do up to 15.4W per channel at AT POE qualifications with an extra PSU module. I dont currently have the module, but its nice to have that futureproofing.

bought it here by the way; http://hardforum.com/showthread.php?t=1788546&highlight=

Good switch, but even POE+ won't provide 2A of current. As bman said, you could do a shared 12v power supply and snake separate power to the Zyxel Cams to alleviate the local need for power.
 
jbrukardt, thanks for linking from the Hotdeals thread. The Swann cameras seem very interesting, but I am wondering why you choose them?
 
I'm currently running 6 1080p cameras from a costco combo deal - a lorex system. DVR is sitting in my warehouse somewhere. :rolleyes: I'm running Blue Iris.

The cams are rebranded HIKvision equipment, and I'm pretty impressed with them, personally.

Anyways - if I were to get more cameras I would love to check out Empire Security's stuff, they look decent.

the price was one. The quality was the other.

They are true 1080P, with hefty IR LEDs on them, which makes outdoor viewing vastly better. All that coupled with POE makes for a minimal wiring impact security system for my home. I got 6 good-quality 1080P video cameras for 1200 dollars, when a 1080P bullet is usually at least 400 a piece. And, I got a free NVR which i can ebay off for 300ish bucks with it, as i plan to use Blue Iris.

empire security is one of the few places that sells dahua in the united states, theyre good stuff.
 
my Swanns are also HIKvisions. I dont think the Lorex system was out when i bought mine.

yep, this is what ill be doing.

The PTZs are my indoor cameras, so snaking is a bit easier. ill run some fire alarm cable along with the ethernet, and tie it together on a master 12v bus under the house.
