Help selecting switch to deliver PoE

Recommended Posts

Hello folks, I'm currently designing a system with 40 IP cameras and I would like to deliver power over Ethernet. Can somebody please recommend me a switch/es to accomplish this.

 

Thanks.

Thanks for your reply. I check the switch and find out just 24 ports can be enable to be PoE. Im trying to power all the cameras just with one switch but it seems that I will have to go with at least two.

 

Also I was checking one this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16833122204

 

And according to this: http://www.netgear.com/business/products/switches/smart-switches/smart-switches/GS748TP.aspx#two

it has PoE in all 48 ports. Im just not sure if it will handle the job properly.

Will your camera switch be carrying any other traffic?

 

I will dedicate the switch just for the system: The 40 cameras, a NDVR and possibly a NAS for recording the data.

Please be wary, although all switches are rated to a certain bandwidth measurement, not all can handle that bandwidth being constantly high - as is the case with constant video streams.

 

I would not try for a single switch as this gives a single point of failure that would lose all cameras - having multiple switches is a much better idea.......we use these, but they are re-branded I assume

Thank you for your reply. I will have that in consideration. Definitely its better to have the load distributed plus in case of failure half of the cameras can still be working.

Your system will be useless if your server or NVR are on the switch that fails. For our network I have two (2) switches, one which services the LAN and a second (identical) switch which has been preconfigured and is on standby. In event of failure I do a manual swap. I also have a failover unit for our firewall; I guess it all depends on how far you want to take it.

hi,

it seems that more and more poe solutions these years.

 

tips:

power budget: remember to consider the power consumption of the poe switch itself.

standard: IEEE802.3f/at , the best is to choose the poe switches which is compliant with both.

I agree with q2u - all eggs in one basket - 1 switch for all means a catastrophic failure if anything goes wrong with the switch.

I would split it into 2- providing less traffic for each switch to handle, you don't want to be running the switch at its max constantly.

always good practice to build in a bit of redundancy and allow for expansion.

depends on how you feel about losing everything if the switch fails - downtime till you get it repaired or fit a new one.

I would look at enterprise level switches, like the higher end Dells or the low end Cisco Catalysts (high end Cisco Catalysts are more then a new car)

 

Also you need to count those watts as well, just because you can get a 24 or 48 port POE switch does not mean all ports are going to have all the wattage necessary, so check up on that as well

 

Does your NVR have dual nics? You could buy two switches and have each on its own network.
