DS-2CD2142FWD-IS Power Supply?

[GMD99]

I bought this camera sometime ago with the intent to connect it to my Hikvision NVR powered via PoE. However now I want to place it in a location that cannot be powered with the PoE. So I need to buy a 12 VDC power supply.

The specs say...

Power Supply: | 12 VDC ± 25%, PoE (802.3af Class3)
Power Consumption: | Max. 5W

Will any 12 volt power supply work or do I have to have a specific type?

Any 12V DC 1A or more centre positive will be fine.

Not sure what you mean by "in a location that cannot be powered with the PoE", but if you mean that it cannot be connected directly to the NVR PoE, that's fine. You can still use a PoE injector like a TP-Link Gigabit Ethernet PoE Injector Adapter (TL-PoE150S). $15 on Amazon. Put it right next to whatever drives the Cat5 for the camera (i.e. router, AP, switch...) and you're done. No need to find the right AC adapter or figure out how to run the DC wire.

Thanks for your post... however I went ahead and bought the power supply suggested by Alistair. The location of the camera lends itself well to using a power supply, so I'm happy with this setup.

The PoE injector is a good and valid suggestion, though, and worth bearing in mind for any future changes.
Something to consider is how easy (physical access to what's powering it) would it be to power-cycle the camera if that is ever needed.

Hi. I Have similar camera
DS-2CD2142FWD-IWS.

In manual says: Use a power supply 110-240V~, 47-63Hz,
2A / 12 ---..., 5A (connector with positive central).

Do I must use 2A adapter for good working?
But it work at 1A i saw..
5A is maximum which go on this camera?

 

[alastairstevenson]

As the camera will consume less than 0.5A the 1A power supply is more than adequate. A 2A supply would be ok as well, just a bit wasteful.

Aha. Is that what's on the box
write 12V ---... 0.6A means that camera need only 0.6A to work (even in wireless mode)?

Yes, that's correct, though it's usually the IR LEDs being on that causes the maximum power draw.

Ok. I will use 1A charger.
Thank you.
