1.1.2 Advantages and New Features
The high-resolution D25M MonoDome is a universally deployable, highly innovative and
easily concealable camera system. A powerful successor to the D24M, the D25M features
five-megapixel image sensors. For technical reasons, the live or recorded images displayed
by an D25M sensor have a maximum size of QXGA. However, the D25M is clearly superior
to the previous model in terms of image quality and frame rate.
Smooth HiRes Video Streams
The modified hardware of the D25M transmits the camera‘s video streams even more
smoothly than the high-performance D24M, even when high resolution is required. Since
image streams of 16 frames per second and higher are perceived as fluid video by the
human eye, the maximum frame rate is limited to 30 frames per second (when using
MEGA resolution of 1280 x 960) in order to provide sufficient camera processing power
for other tasks.
Conclusive Still Images
Thanks to the proprietary MxPEG video codec developed exclusively for MOBOTIX cameras,
the cameras offer the advantage that a recording can be paused at any given point and
still provide meaningful and useful snapshots due to the absence of distortion. This is
essential for security applications and allows individuals or license plates to be identified,
for example. In contrast, the H.264 standard, which was developed for feature movies
and is favored by some video security providers, cannot achieve this with the required
level of quality.
Good Color Images Even In Low Light
The more light-sensitive an image sensor is, the better the image quality, especially when
the ambient light level is low, such as at dusk and in heavy rainfall. The D25M offers the
best MOBOTIX image quality that is currently available thanks to the light sensitivity pro-
vided by the five-megapixel color sensor that is four times higher than that of the previous
three-megapixel color sensor and the new MxLEO exposure control.
More Details When Zooming
The maximum zoom factor of the D25M is 1.26 times higher than that of the S14 due to
the use of five-megapixel technology. This means that the degree of detail provided by
the camera has improved by 26 percent. As a result, an D25M can now be installed even
further away than before from the objects and areas to be monitored. In addition, this
relativizes the horizontal image angles of the new five-megapixel sensors that are slightly
smaller compared to the D24M.
Black&White Image Sensor with 5 Megapixels
You can now order the D25M with a five-megapixel night sensor that can deliver black
and white images with up to QXGA resolution. This results in larger images than those
delivered by the previous 1.3-megapixel sensor with a perceptibly higher degree of details.
