Hello

I am thinking of investing in a D-Link or similar Switch with POe ability , 

 

I have a AVM542 Outdoor Camera , and it specifies 12V 1.5amp as power source. 

So my question is , do Switches that provide POE always output at 12V ?  every spec I see is only shows Watts , --> DGS-1008P

I
s POE ports a standard Voltage ?.. 

Thanks in advance for any help guys. 

Rhys

True PoE is 48V in accordance with the 802.3af spec.

In reality PoE these days is a mix between active 802.3af and passive PoE that delivers power over pins 4,5 and 7,8 using whatever voltage a device requires.

That camera says it's 802.3af so will will work with any 802.3af switch. It probably also has a DC connector so can be powered using 12VDC if PoE is not used.

Damn Jaycar are expensive. Those passive injector cables are only about $1 each to buy from usual sources.

They have always been expensive, and made 10x worse by Disksmiths moving out of the electronic market.
