hi, i hope someone can answer this, im using a sensormatic system, speed dome cameras, intellex systems, i beleive pelco, all ptz are switched to 893, so recently i obtained 2 ptz, and basically just plopped them into the system and it was fine, i later obtained 2 more ptz's possibly older types, and i tried putting them into the system, i get video, and the camera is doing its checks, then theres some words on the screen (cant remeber exacty what) but also what shows up is CHECKING NETWORK TYPE, that stays there and thats it, no control over the ptz however i can see video. any ideas? thanks
