Office Security System

#1
Hi, we are moving to a new office soon. Need a good security system for the office.

I'm looking for something that can be customized. Moreover, It should be easy to operate. And should have features like access control, security alarm, video surveillance with high definition night vision camera, good cloud storage, a mobile monitoring facility, etc.

Already got some good options from a firm here in Vancouver that provides residential and business security systems. Though I would like to check other options too. So please share your suggestions.
