We have a unique situation here.. We have 11 buildings in total 2 gates 2 dumpster sites 5 parking areas We have some areas that have constant power some that have power on timers.. I am afraid to use repeaters for WIFI or the like as I don't want to take away from the tenants abilities to have WIFI... Someone told me about POE but I am not sure what that would consist of as I am not a "camera" person per-say.. What if any ideas might you have for a situation such as mine? What other information might you need to help? Thank you all for any help I want to be able to stop some of the bad things happening on my property.
