Guidelines for Spec Sheets
Requirements for Surveillance Systems
The requirements listed in the following represent the minimum requirements for surveillance systems, if
they are to be considered state-of-the-art technology:
➢ Video surveillance has to deliver images with a minimum resolution of 960 lines per image per
camera in order to guarantee that persons and objects can be identified properly in the live im-
ages.
➢ The camera images need to be recorded with at least 960 image lines in order to guarantee that
persons and objects can be identified properly in the stored images.
➢ The system has to allow for simultaneous display and storage of the live images as well as the dis-
play of the stored images and video sequences without the risk of loosing data.
➢ The system needs to be able to record at least 20 smooth video streams simultaneously on one
standard computer. The recorded video streams need to contain at least 10 images per second.
➢ To reduce costs, the system should not require additional power lines for the camera's power sup-
ply. Instead, power should be supplied via the network cabling (e.g. Power-over-Ethernet).
➢ The system needs to be able to operate in outdoor applications at temperatures between -30° to +
60°C (-22°F to 140°F) without any additional heating in the surveillance cameras. This will reduce
power consumption to a minimum, thus providing for cost-efficient protection of the whole system
using uninterruptible power supplies.
➢ The cameras should not have to rely on any moving parts such as auto iris, mechanical filters, mo-
tors, fans or similar. This ensures that the complete system is highly reliable and maintenance-
free.
➢ The surveillance cameras need to be able to bridge at least a one-minute failure of the data con-
nection or the storage device without losing any storage data, images or video sequences.
➢ The surveillance cameras need to able to output voice messages and to react to sounds in the
camera perimeter and to trigger alarms accordingly. The system needs to play back and store the
audio signals in a lip-synchronous manner.
➢ The cameras need to employ wide-angle lenses with an image angle of 90 degrees or more so
that the monitored areas are covered as efficiently as possible.
➢ The system needs to be able to integrate analog cameras (e.g. PTZ cameras) seamlessly. This re-
quirement is valid for displaying and operating the cameras as well as for storing the correspond-
ing images or video sequences.
➢ The housing and the materials have to be chosen in such a way that the cameras have a life ex-
pectancy of at least five years.
