Guys I will like you to use your intuition and give me your opinion on what are the chances and challenges of operating a security business in Nigeria, that can provide alarm system installed to clients and a monitoring station to indicate a break-in?

According to President Obasanjo, Nigeria is a grossly under-policed state. So I think security is a lovely business. We have to prevent crime because there's little that one can do after it has happened.

How would a monitoring system work with such an eratic power supply in the country? You will continue to have spurious alarms due to power fluctuations and PHCN / GEN switch over. I'm sure there are way's to overcome this however I would suggest delaying in the alarm side of thing's and concentrate on Security personnel training. Good luck.

You can power your security alarm with UPS system that runs from a battery when NEPA is not available. A security alarm doesn't require much power, you know.

Yep your right, a UPS would be good for individual homes. But do you think a monitoring system (I read that as a central control room covering multiple properties) connected to multiple UPS would work? Do you appreciate how sensitive alarm's need to be to detect line breaks? It could work but I very much doupt it (My opinion) it would be an expensice mistake if it does'nt.
