how does it get power? Battery, wired or both?

It comes with a 12 vdc power supply that plugs into a 110 vac outlet. It can run on a battery but will take .5 amp during night operations.

It comes with a power supply, doesnot use batteries, and is not POE (power over ethernet) enabled.

The cameras are installed so I do not remember if they can use batteries and it`s difficult to take a look now. Better verify the specifications at Trendnet` site. In my case I`m powering them with the 110/220V AC converter they provide. One point of attention, I could not find yet a cloud service that could record streamings from this model. Camcloud only record static images and Trendnet cloud services do not make records, they only have Live View.

It has a plug that plugs into a wall outlet, it recvs and broadcast thru WiFi to your router. It was very simple to set up and works fine.

Its self powered. So just plug into it and youre good. It works solo or you can daisy link them together.

It needs both, you can run it for a short time on just batteries but some features will be missing. The batteries are needed to maintain operation when power fails. You should always have AC power and batteries.

Wired directly to the battery.. The sole purpose of it. If there is a fire you can kill all power!

Its a 12 volt power outlet to be wired to a 12volt battery, similar to a cigar lighter in a car, but can be wired where you want it.

For power it comes with a plug-in transformer you can use if have a way to run the wire from AC to the doorbell, or it can run on two AA batteries. I have one on AC and one on AA, both work just fine. They are wireless from the doorbell to the base station.

This is both battery powered and has an AC adapter. The lamp works well with either source of power.

You can do both. It has a cord which you plug in and it also has a place for batteries.

the battery is for backup only..... in case electricity goes out. You still need to wire it.

It is powered with a USB cable and plug that they provide. You can leave it plugged in all the time or let it run off the internal battery and just plug it in to recharge the battery. Some functionality is sacrificed if run off battery power to conserve power. I'm going to see if I can cut off one end of the usb cable and permanently wire it into the vehicle.

This unit is powered from the voltage of the wire. No battery. There was is another model number that bruns from battery. I install those models. Just search it.

there is a voltage converter you simply plug in. That part of the is wired.

The great thing about this one is that it has both options. It's a plug in but they also wire it in case you want to hard wire it.

It is powered by the USB connection and doesn't require an additional power supply. It is not wireless and must be connected with the USB cable.
