as I said before: If you have Enterprise-grade requirements, don’t expect Consumer-grade solutions and prices.
And i second this strongly.
except, the breaking in WILL happen. Regardless of security system or not. Question is, does your security system meet the requirements to have police/security on the spot within seconds to get the intruders on the go? or do you only end up with a blaring alarm sound, everyone is already ignoring and some blurry videos with no indication on how to catch them?
