these are all ip cameras. the behavior has slightly changed now. even with only two cameras active, the icamsource app will just randomly die. once it dies, it will never restart. i have to manually remove and recreate the plist, which is absurd!
as i said, i have used this product for years without issue. now it won't stay up at all with the same exact configuration - no new cameras, no new network equipment/config, etc.
frustrating and baffling.
