POE what do you guys use?

[Media 0]

I order some IP cameras.. I'm not sure which POE to use

 

any suggestion?

[Sawbones 0]

I just bought a Netgear switch that has four 10/100 ports, and four 10/100PoE ports (total of eight) for a hybrid system (two axis camera servers and a couple of IP cameras).

 

It's this one:

They seem to be out of stock at the moment, but I'll try to post back when I've got everything hooked up.

I too use Netgear and it works fine, FWIW.

 

Best,

it is ok switch

but it will cut your bandwith by 30-40 %

that why I stop using them

used these in a recent install..works great

My experience with rack-mounted equipment is that they rarely pay any attention to how much noise the item produces. They figure it's going into a rack in a datacenter or wiring closet somewhere, so they put these tiny 40mm fans in them... and they're literally like sitting next to a hair dryer.

 

My current rack-mount switch (a 16-port Linksys managed Gigabit switch) was horrendous... bad enough that I took it out of the rack, took it completely apart, removed the two tiny noisemakers-disguised-as-fans that they'd installed, used an 80mm hole saw to cut a hole in the top of the casing, and installed a low-profile 80mm fan+grill (just enough clearance that it didn't hit any of the internal components.

 

The result? Ultra-quiet, and it moves more air through that switch than those tiny little fans ever did.

 

The only downside? I voided the warranty.

What are you using now?

 

by the way the camera are acti 3401

10/100 would be fine i think for 4 cameras or what do u think

It's my first time testing IP stuff

 

another question is can i use Cat6? instead of cat5?

 

Does the POE send out 12VDC or higher? i 've heard some stories the POE burns out IP cameras

[Monitor Your Assets 0]

For home, I use a 3COM 10 port switch (3CDSG10PWR). It's a managed switch, has one SFP port (just in case), is rack mountable and has a quiet fan!

For customers, it's generally a case by case basis. The bigger shops tend to stick with Cisco because it's well documented and well supported.

Yes, you can use Cat-6 instead of Cat-5.

 

The current/popular flavor of PoE (802.3af-2003) is rated at 15.4W, but one must account for loss over the length of the cable. An upcoming flavor of PoE (802.3at) will deliver 24W of power.

I've used a LinkSys SFE-1000P for two different sites now, and been pretty happy with them. They have eight 10/100 PoE ports and two fiber/GbE (gigabit ethernet) ports - cameras go on the PoE ports, DVR and NAS RAID rack go on the gigabit ports, and everyone gets along nicely! They have management capability as well, but I haven't yet had need for it.

Sure, they're just two different types of wire.

Current PoE supply spec is, I believe, 48VDC at up to 15.4W, as MYA notes; PoE devices should be able to operate on anything over 12-15VDC, so line loss shouldn't be an issue except over a VERY long distance... and remember that ethernet over Cat-5e is limited to 100m anyway.

 

 

Cameras should not be burning out unless: a) the camera doesn't adhere to the spec; b) the source doesn't adhere to the spec; c) there's a serious wiring problem. I've had a couple cameras die on PoE, and it was specifically because of a wiring problem.

-- LinkSys SRW2008MP -- Very loud. I've had two of these switches fail; but LinkSys support was good in replacing both units.

 

-- Netgear FS108P

 

-- SMC SMCGS8P - Quiet, 8-port, Gbit.

concerning CAT6 over CAT5.....why use CAT6? CAT5 has plenty of bandwidth for a single IP camera............it's a waste of money. Especially since IP cam technology continues to shrink bandwidth use.

 

I can see CAT6 on runs that will be increased to Gigabit with the intent of needing gigabit bandwidth.

 

yea, you can use it, but.........why use 10lb. sledge when a hammer works? The increase in cost is not warranted. Technology just might overcome/pass up wired links.

[Soundy 1]

Depends on the situation... if it's a new install, new construction, going all Cat6 is probably preferable for the long run - not only are you future-ready, it's probably more cost-effective on the whole to buy only one type of cable (bulk pricing) and not have to mix-and-match different cable types.

BTW, that Netgear PoE switch I mentioned up-thread works just fine. I posted a picture from a PoE ACM-1231 camera in one of the ACTi threads... no issues at all.

What i meant before is

that I could not get full bandwith from swtch

 

Example

 

I had Arecont 2 and 3 Mp working no problem with this switch

but at no more then about 60-70 % of max bandwith

i connect through gigabit sw and got full bandwith

then i tried another the same switch

the same problem

 

lots of company i notice do not measure bandwith

 

 

but on another hand your Acti most likely do not need more then 10-15 Mbps

[Sawbones 0]

Ah... I see what you mean.

 

Yes... with protocol overhead and such, you're really only going to get 70-80Mbps out of a 100Mb switch. You can get significantly more out of a gigabit switch, but then you get into jumbo frames and other peculiarities that you need to really optimize a gigabit switch's capability.

 

You also need high-quality network cards... generic chipsets sometimes leave a lot to be desired. I lean towards the Intel Pro 1000Mb cards... always had good luck with them.

Microsemi formally Powerdsine makes very good POE midspans

Cat5 and cand cat6 have the same *network* bandwidth. Gigabit is supported just the same on both.

 

Cat-6 however, is a higher quality cable, reducing the possibilitly of inteference and ability to do better at longer lengths. So to the extent your cable is getting routed through noisy environment, it is a better bet.

 

Not an issue in this space but for extending HD video over HDMI, cat6 is recommended over cat-5 because there, we don't have retranmissions.

ive used adtran poe 24 port switch.. its solid
