We look forward to working with you and helping make your property a more secure location. I think that there might be a solution to this problem, but only if you really like the camera a lot. You could likely go out and find a type of battery for it. Then, you can rig the camera so that it has a battery backup. But, the downfall to this is that the camera was never intended to be dual featured like this. Will it work properly after making this modification?No way to tell. I do not think that I would be brave enough to do this on my own anyway. Also, you would have another problem of making sure that the batteries were always charged and in working condition. It would really funny if power actually did go out and then your back up battery system conked out because they were not charged. Also consider your level of technical expertise and mechanical ability. If you are someone who likes working with their hands and enjoys putting something together, then you may have more options than someone like me.
