dmz is worst case on most routers?
id say most customers don't care as long as it works.... Trying to explain the reasons why make you the over charging numpty who charged for stuff that wasn't needed
the sound bombs require remote power
The prem is not a proper fire panel
If you want 'proper' fire then use proper fire kit. DO NOT use intruder gear in a fire alarm
why would anyone offer Imo the best comms (watch this space too) for free? Everything costs id rather know the up front ones vs the hidden ones.... Do you really believe the free ones won't need a full system replacement to keep it running?
funny enough re hkc I just fitted a system (friend believe it or not) on a few gates on a small farm. no waterproofing like that test I did 5 yrs ago on my house. Still no issues and furthest gate is over 500m away
