Hi - in the PM you asked about power during the daytime - I wanted to share with others A) passive injector for one 20 watt flood is the ( follow link) WS-PS-48v30w plus this WS-POE-1-WM Daytime power is zero B) there are many poe+ switches - like this...

Sure - send me a private message - we can work with you.

Hello - we now also have a Dusk / Dawn 20 watt model with PoE+ / 802.3at compatibly on our website at atxled

One thing to consider, is the electrical engineering difference between passive and 802.3af or "true PoE". It is about the voltage, not passive vs "true". A Hikvision or such camera can operate at either 12v from a wall wart, or 48v from the ethernet cable. If you try to extend using...

Hi, if the cameras are truly PoE - then this is a lower cost, very rugged PoE switch http://find-a-poe.com/product/WS-POES-8-7-48v60w/ - it only uses 2 watts itself, so it needs no cooling, and can operate in tough environments. if the cameras are similar to the Foscam W type (non PoE) then you...

I am sure cameras exist at faster than 100mb/s data rates - say in raw mode and 30 frames per second - that is just 150k RGB pixels in raw mode to hit 3.3 mbit per image. But with compression in modern cameras so good, the bandwidth used for most applications is far below the raw data rate...

If you have a switch already - you can add 16 ports of PoE for $125 here http://www.amazon.com/gp/product/B00IJI0U78 there are also 8 port and 12 port versions of this midspan injector to add PoE to any existing switch or router. No Fan. Dual power supply option for failover.

You can add PoE+ to any non-PoE switch port with this passive midspan injector http://www.amazon.com/gp/product/B00KHD6V26 for 120 total watts (there are also 144 and 240 watt versions)

We have a web page to answer the question about distance with PoE. http://wifiqos.com/poe-calc.html there you can input the voltage, and it will calculate the loss in the ethernet wire over distance. Using that tool, one can see that it is the Loss in the cable that determines the max...
