Actually the software should take the boring part of video monitoring and attract the human attention to recognise dangerous situations only.</li><li>Sometimes the length of the video archive storage space is just too short. To prevent this the system designer must do <a href="http://www.jvsg.com/bandwidth-storage-space-calculation/">CCTV storage</a> estimation to choose a proper disk volume.</li></ul><p>Wrongly made CCTV systems are just wasted money.
