How do you connect to power source?

With my application there were already existing wires and a transformer. All I did was replace an older unit. By the way you asked your question makes me think you should have a qualified electrician install this unit.

We bought it before starting the enclosed porch where we mounted it, and it gets power from being connected where the doorbell is connected.

I was just replacing the original one. Power source was already available for mine to be installed.

Dear Janet,Wiring instructions illustrations look more complicated than it is. Just connect the two wires to any low voltage tranformer. Just be gentle on the install. This is designed to connect to your existing doorbell transformer for power. If that's not your plan, you need a transformer to supply power. thank you for your interest!

There is no power chord. You need to purchase 12/2 wire and plug to connect to the power source.

I would go to Radio Shack and ask how could connect. I don't have this problem.

Thanks, If I can get/keep a connection I'll try downloading the driver. Already did the power saver. No luck for me there.

USB Cable connects in the back and the other end can be connected to a computer USB Port or to a USB electrical adapter that plugs into the wall for power. You will need to purchase these seperately. Kirk B. answered on December 29, 2013

They are just different ways of connecting, one by screw block and one from a power adapter plug. It depends on what you are going to power it from. The negative screw block terminal is very useful as well to connect the grounds of the source signals and the power adapter so you have a common ground.

use the USB cable that comes with it. plug it in using the micro usb and the other end into your computer or an AC adapter.

A power supply is not needed. Just plug in the 2 usb plugs to your computer. Power comes from the usb connections. If you don't have 2 usb connectors, try Radio Shack or Best Buy to match the plug needed.

To supply power to this caerd, you have to have a powered USB port available. Plug the included cord into your existing on-board USB port and plug the other end into the small connector in the middle of the card.No added power for things like wireless mouse adapters or thumb drives, but needed for things like external drives and cell modems.

I had to provide my own power source. Power is not wired to these points on the circuit board. Start with a simple continuity test using an ohm meter.

No you do not - simply connect it to the GPIO headers on a raspberry pi. The connector on the bottom is where the unit draws power from.

I have mine plugged into a PSU. This is likely the only way to receive power.

The other answers are correct. This needs to be plugged in to a power source.

The next comes with a connector you plug into then. Then get a molex plug to get back to a power source.

You just plug it into the computer via USB drive and set it up that way and you are ready to go. No other power source needed.

Just run the wires down to a 12v power source and connect them using solder or proper wire connectors.

With the USB cable that is included. You can either plug it into your computer or a wall outlet converter (http://www.amazon.com/Wall-Outlet-Converter-Power-Buddy/dp/B00C7GH8UK).
