in home security systems
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. Personally, I am not mechanically inclined so I never really intended to build or put together my makeshift system at all. On the other hand, you may be surprised to find out just how simple and easy to install some of these modern cameras really are. I have put in at least 20 different types of cameras all on my own. Some were a bit difficult, but most were surprisingly easy and simple. Usually the instructions were very clear. The times when it became difficult, I was able to jump online and check out some plans, instructions or even videos to guide me through the difficult parts. My point here is that you may actually surprise yourself with what you can do when you put your mind to it. This camera from Clover Electronics, the HDC518 CCD looks very sturdy.
