Media 0 Posted March 7, 2009 I order some IP cameras.. I'm not sure which POE to use any suggestion? Share this post Link to post Share on other sites
Sawbones 0 Posted March 7, 2009 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: http://www.newegg.com/Product/Product.aspx?Item=N82E16833122152 They seem to be out of stock at the moment, but I'll try to post back when I've got everything hooked up.

cglaeser 0 Posted March 7, 2009 any suggestion? I too use Netgear and it works fine, FWIW. Best, Christopher Share this post Link to post Share on other sites

VST_Man 1 Posted March 8, 2009 for the bigger boys http://www.newegg.com/Product/Product.aspx?Item=N82E16833122077 used these in a recent install..works great Share this post Link to post Share on other sites
Sawbones 0 Posted March 8, 2009 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. Share this post Link to post Share on other sites

Does the POE send out 12VDC or higher? i 've heard some stories the POE burns out IP cameras Share this post Link to post Share on other sites
Monitor Your Assets 0 Posted March 9, 2009 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! http://www.3com.com/products/en_US/detail.jsp?pathtype=purchase&tab=features&sku=3CDSG10PWR 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. 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 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.

Soundy 1 Posted March 9, 2009 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 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. another question is can i use Cat6? instead of cat5? Sure, they're just two different types of wire. Does the POE send out 12VDC or higher? i 've heard some stories the POE burns out IP cameras 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. Share this post Link to post Share on other sites
skane 0 Posted March 13, 2009 -- 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. Share this post Link to post Share on other sites
VST_Man 1 Posted March 13, 2009 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. Share this post Link to post Share on other sites
Soundy 1 Posted March 14, 2009 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.

Sawbones 0 Posted March 14, 2009 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. Share this post Link to post Share on other sites
ak357 0 Posted March 14, 2009 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 Share this post Link to post Share on other sites
Sawbones 0 Posted March 14, 2009 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.

amirm 0 Posted March 15, 2009 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. 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. Share this post Link to post Share on other sites
