One of my friend's electric bike was stolen last week. Theft in his locality is very common. So he's planning to install a security system in his outdoor. Which will be the best security system? Wired or wireless security system? Both of them have pros and cons (http://www.fire-monitoring.com/benefits-wired-vs-wireless-security-cameras/), so he's a bit confused to take the correct decision. It will be really helpful if you suggest your ideas.
