2.3.3 Deciding on the Connections (Network/ISDN/RS232
First, decide on which camera connections you would like to use.
Network is key
In general, you should always provide a network connection, if technically possi-
ble (a WiFi connection using a bridge or similar would also be acceptable), since a
network connection brings a number of advantages:
• The highest frame rate is only reached if the bandwidth is high enough;
ISDN and GSM/GPRS will
not suffice to deliver smooth video images.
•The camera's external ring buffer (storing the video/audio data on a file
server) can only be used via a network connection.
• Compared to the costs of dial-up connections (ISDN, GSM/GPRS), the costs
for file transfers and other accesses by and to the camera are reduced con-
siderably when using a network that is already up and running.
• Software updates are best accomplished using a network connection, if dis-
mounting the camera is not an option.
SIP telephony reduces costs
ISDN connection of MOBOTIX cameras is not required if the network permits SIP
connections for Internet phone connections. Thanks to the SIP capabilities of the
MOBOTIX D12 (see chapter9,
Telephony Features , in the Software Manual ), the
camera can place voice calls (e.g. for alarm notification) via the network and can
also accept incoming voice calls via Internet telephony. You can call the camera
from a phone to obtain the time and date of the last event, for example.
