I use these to protect my home SOHO because I want live agents watching my place 24/7! The staff is super nice and I know the CEO on a first name basis. http://bit.ly/deepsentinel
If you want some cameras from your business then I would check out https://amcrest.com/ have their cheap 1080p https://amcrest.com/amcrest-1080p-wifi-video-security-ip-camera-pt.html in my enclosed porch for years without any issues. If it can stand the cold of the north country imagine how well a proper outdoor one will work? 
Here is another wire-free option https://reolink.com/product/argus-2/
I also recommend Noonlight http://bit.ly/smartisnowsafe which is a free panic button for Android users. Iphone owners have to pay a small monthly fee. Only because they have not made a pay gate for Android yet...
