    i just received two cameras, why can i access the first one but not the second?

    answer: the devices are shipped with a default ip address of 192.168.1.4 for easy setup. however, each camera has a unique mac address. the operating system may cache the previous camera's ip and mac information. when setting up the second camera with the same ip, use the command "arp -d" to clear the cached information before connecting.
