POE switch help

Recommended Posts

Hi

 

I am attempting to set up an 7 camera system at my house however i have no idea about POE switches. My knowledge of POE switches is that generally speaking only half the ports in a system are POE (system dependant obviously) and you should look at the maximum output of unit as it may determine what the actual maximum output of the ports are (if they are all in use). I have seen people talking about gigabit systems, are gigabit ports also capable of powering IP cameras (from what i can make out it is essentially the same but capable of higher transfer speeds)? Because of my lack of knowledge around POE switches, I think it may be best to go for an unmanaged port so that its not a complex.

 

In my searches I have found a couple but not sure if they are compatible. My cameras are Hikvision ds-2cd2032-i (i think they require 5W and 7W with infra red). Can anyone please advise if the following are suitable or recommend a POE switch (i am planning to extend our house in the future so may be adding more cameras). Ideally a D-Link or Netgear POE switches because they are easy to come by here in Australia for a reasonable price.

Managed/Unmanaged

A managed switch lets one log in and configure the data-traffic a little better...as well as monitor data traffic too. For a home/small business, a managed switch is typically overkill (and unneccessary cost). An unmanaged switch works great for 99.7% of the home/small business situations.

 

For the power-part (POE), the managed switch doesn't add anything for you as the managed part is to handle the data details.

 

Gigabit

Handles more data, not related to the power (POE) part. I'd use these when the rest of the network is also Gigabit. A camera, or computer, may only be sending some 5-10 megabits each, but a gigabit (1000Mbps) network would't max out nearly as soon as a 100Mbps would.

 

Compatibility

99%+ of the POE switches will do the job fantastic, hands down. Just plug it in and go.

 

Distance

For just 50' or 150'...I rarely, if ever, have any issues at all.

When I get out to some 200' or 300' lengths of cable, sometimes I do run into a couple of POE switches that don't seem to send the juice out as well as others. Rare, but I see it more at long distances.

 

I've used Zyxel regular switches on some LANs, but not POE, so I'm unfamiliar with them. But I wouldn't expect them to be an issue. The D-Link-brand (and Netgear, TPLink, TrendNet), I've used many times without issue for small 8-16 port applications.

 

Ports

The main issue I hear from my customers is that later down the road...they want more cameras. So getting a switch (and NVR channels) ahead of time with that in mind, then it's easier to add to the system if there's open ports still.

 

Some brands/models of POE switches do only have half the ports powered. But many of them have all the ports powered.

 

Juice

Yes, if you can, look for total output of the switch as well as per-port output. There are named specifications in the 802.3 (such as af, at, etc), but the bottom line is if it's providing the juice you want. More reading here:
