Running IP camera off batteries


I am working on a project for my computer science degree and have run into a problem.

My project is to control a small chicle over the internet. Currently I have it all working except the fact that I am unable to power my IP camera by a battery pack.

On the actually camera it states DC 5V and on the power adapter it states OUTPUT 5V===2000mA

This is what I have bought so far

5v regulator

Battery holder

Rechargeable batteries

If anyone has any ideas how i can get this IP camera running off batteries then please let me know.

Thanks in advance.

  1. Your Ic only supports 1A. Your camera need 2A.
    You need something like this:

    you will need to give it more than 5V to ensure proper regulation, this one has a minimum of 8, you might get by with 7.2V (6 1.2V rechargeable cells) but 7 would make it up to spec at 8.4V (wired in series). May need a heat sink on the ic. Theoretical 100% efficiency would give you 3360 mAh at 5V I think? or 1.68 hours of runtime if it actually pulls 2A@5V. so maybe an hour and a half realistically.

    I only do hobby electronics, there are plenty of people here who know more than I do. Also, there are other sites that are dedicated sites for these things.

    Be careful, it is easy to fry stuff when you make custom power supplies....
