I do apologize that you having issues with your camera.
Sounds like you having some type of power drain on your batteries?
Without going into a bunch of deals lets first ask you this, What type of batteries are you using?
Most batteries that are bought under $5 bucks will not work in these types of camera's successfully. Please check the back of the battery package to see what devices are supportive. I recommend batteries.com for high grade long lasting batteries. I also recommend recharge-ables so your not wasting your hard earned cash on something that is going in the landfills.
Now the alternative power source for this would be better batteries. Now if it drains rechargeable like it does the ones your currently using then the device would have a fault inside somewhere. Please consider using rechargeable first, if you have any questions let us know asap.
