1.1 The Concept Behind the MOBOTIX D12
High-Resolution Live Video (640x480) with up to 30 Frames/s
The second generation of cameras from MOBOTIX now delivers smooth live video
display in VGA format with synchronous live audio, yet it keeps the network load to
a minimum (approx. 2Mbps). Live video display now match the performance of
analog video systems. When recording, MOBOTIX systems easily outperform ana-
log systems, since MOBOTIX cameras store the same resolution and quality with
the same frame rates as in the live display. MOBOTIX technology thus allows si-
multaneously recording the video from 30 cameras in continuous recording
mode on one standard PC at 30fps each, including the audio channel of the
cameras.
Low Bandwidth Requirements
MOBOTIX' patent pending MxPEG streaming format allows fast live video with au-
dio at extremely low network load (1 to 2Mbps). Since the MOBOTIX camera itself
detects movements in the image, video is only transmitted if movements occur,
and when the video and audio data are stored.
Voice over IP and ISDN
Moreover, MxPEG provides for synchronized audio and two-way communication
between the camera and your computer. Room surveillance with audio is possible
using Internet Explorer or MxViewer. Alarm notification on your mobile via Internet
(SIP) or ISDN telephony is just as easy as event-controlled voice messages directly
from the camera.
IP Telephony and Video SIP
All telephone features can be used via Internet telephony thanks to the integrated
SIP client. The SIP client allows remote-controlling the camera using the touchtone
keys and also places the alarm calls of the camera. Video SIP establishes audio/vi-
deo connections to the camera using Windows Messenger or similar applications
(e.g. Counterpath x-Lite/eyebeam).
Long-Term Storage Included
MOBOTIX cameras have an integrated long-term storage system for Linux,
Windows and Mac OS X computers. Every camera manages its own storage space
as a ring buffer on the shared folder. Thanks to this decentralized approach, 30 live
cameras can store images on a regular Pentium 4-class computer with 30 fps
each, including audio (also depends on the operating system).
Event Storage on SD Card
An SD card can be inserted into the integrated slot to increase the internal memory
of MOBOTIX D12 cameras (SD cards will be supported after a software update,
which will be available at the end of 2006). A 2GB card can permanently store up
to 65,000 images in CIF format, 40,000 images in VGA format or 13,000 Megapixel
