Digital technology

Digital camera systems are replacing classic analogue solutions. Digital systems are advantageous for users primarily due to their improved abilities for processing image signals and distribution in classic computer networks. Another advantage is the ability to save selected image sequences in high quality on recording equipment - hard disks. These sequences can be played from any location on the data network repeatedly without loss of quality. Image data may also be saved after any length of time. When the decision-making concerns the purchase of a camera system, we recommend digital technology as a common standard.

Advantages

• Record of image on hard disk (HDD)
• Setting quality of records independently on each camera
• High capacity of recording media
• Guarantee of constant record quality during replay
• Evaluation of changes to scenes viewed
• Observation of movement of objects (persons) in the image
• Setting of pre- and post-alarms
• Localization of places in the image (license plate, face)
• SW configuration of cameras and units from one place
• Distribution of video signals to any place(s) in the data network
• Combination with other security systems (ESA, EFA, SKV)

Transitioning to Digital Technology

If you have already invested in the installation of a classical camera system with analogue cameras, multiplexers, recorders and a control room, you will at some time have to start solving problems with decreasing image quality, worn out cassette tapes and rebuilding video recorders. In addition, you will not be able as a practical matter to access shots, at your workplace, for instance. This problem can be quite easily solved by integrating a video server (video streamer) into the analogue system. It will immediately "requalify" equipment and you will be able to start enjoying the advantages of the digital world. These include, in particular, remote access and easy digital sending and saving images. One of the greatest advantages of video servers is that they allow you to remotely view live digital shots (from analogue cameras), anytime and from anywhere using a computer connected to the network. For example, you can monitor the situation in manufacturing while you are on a business trip, or you can check whether an alarm has been activated by mistake. In addition, shots from events that triggered an alarm can be quickly and easily distributed for further investigation to many people in various locations via a computer network.
