cameras ip

good, is there any way to integrate IP cameras with Arduino ethernet, something like that Cameras server when having an event can enter the arduino and reviewing the camera.

If you mean an IP camera server, the answer is: No. The Arduino is much underpowered for such a task. Use one of the Linux based platforms (Raspberry Pi, Cubieboard, OLinuXino, etc.) for projects like this or go directly with a PC-based system.

that's right arduino hasn't the capability to handle video, as much you can controll the ip cameras, pan tilt zoom if they have, check this video it's about a project to control like 20 ip cameras made by myself

good luck!
