I have read were the PoE switch generates heat and may fail if it gets too hot.  How much heat can it take?  I need to put a switch in my shop  for the shop cameras and the shop is not air conditioned.  I am in south georgia and the summer time heat can average mid to high 90's for days on end and may hit over a 100 at times.  Is a PoE switch going to work under these conditions?

Operating Temperature: 0°C~40°C (32°F~104°F)
Storage Temperature: -40°C~70°C (-40°F~158°F)
Operating Humidity: 10% ~ 90%, non-condensing
Storage Humidity: 5%~90% non-condensing

 

Those are the specs for heat

Our PoE operating temperatures vary from 

 

POE-4G1G:

Operating: 0° ~ 45°C (32° ~ 113°F)
Storage: -20° ~ 90°C (-4° ~ 194 °F)

 

POE-24MB2G-M

Operating Temperature: 0 •- 50 • C (32 •- 104 • F)
Storage Temperature: -20 •- 70 • C (-4 o- 158 oF)

I suggest going with an NVR without the PoE switch built in so that both units are cool. Having multiple Devices in one can create heat and in your case where you do not have a means of cooling down your electronics I would go with lets say a 4ch NVR and a 4 port PoE switch. Give me a call if you need assistance in choosing your Recorder.

I was actually looking at the 16 channel nvr and two 8 port poe switches.  The nvr  and one poe switch will be located in my office that is air conditioned. The other switch will be 165 feet away in the shop.  The plan is for six cameras in and around my office and six cameras in the shop.  I have a dedicated cat 6 cable that runs from my office to the shop for the poe switch.  From there the cameras will be located around the shop with a distance of no more than 120 feet from the poe switch.

I don't see any issues with this setup. PoE has not limitations other than normal Data Transmissions cannot go further than 300' from the Router/switch.

Keep the switch low as heat rises and I recommend a small external fan if it really hot in your shop pointed at the switch.
