The CAT 5a cables are good for 1Gb, unless damaged. The 100Mb switch should be adequate too.
How many camers are they altogether? You mentioned 18 into one AP and then 3 more.
I'm still learning towards the AP being overloaded by 18 camera links. I've done a lot of work with WiFi but not seen so many continuous links into one AP. A cheap WiFi router and laptop on its output would prove or disprove that.
Is there any difference in the amount of blocking between disconnecting the longest link or disconnecting the shortest link?
