Office security

The pandemic makes me reconsider the usage of offices I rent. Since many employees now work from home the offices are now quite empty and partially even became storages for hardware we supply. So, the number of people especially during nights became so few I feel it makes our office attractive to robbers. The solution is to set a professional security system. The first I found was Ajax. According to various reviews, the system seems really good. Also, it's very user-friendly due to the ability to operate it with your smartphone https://ajax.systems/software/. But I want to find out about more systems before making a choice. So, can you recommend me any? Which one do you use? What are the advantages and disadvantages?

Much obliged in advance!
