    With the development of electronic technology, such as electronic computers and electronic amplifiers, the modern EEG is basically a digital EEG machine, the mechanical of the old EEG machine is gradually eliminated. And digital EEG machine is constantly updated. Lead number from the initial 8 of the EEG, and gradually upgrade to 16, 32, 40, 64, 128, 196, and so on, and even has a 256 lead eeg.
At the same time, the combination of EEG and imaging system, digital video electroencephalogram (VEEG). In the same time, the video, and through the software to make every moment of the EEG and video images one one corresponding rise, can be seen in the same time, watching the patients at the same time the video, greatly improving the awareness of the event, can be more easy to shave in addition to the false.
    Video EEG as the name suggests, is the combination of EEG and video. According to the lead number of EEG, it can also be divided into 32 video EEG, 64 lead and 128 video EEG, according to need, can also be easily produced more guide video EEG; according to the number of cameras, can also be divided into single camera video and dual camera video eeg. The current trend is a dual camera video       EEG, a shooting in patients with systemic observed overall episodes, another shooting local can be better observed seizures when face and eye subtle movements, such as lip smacking, blink of an eye. The shortcoming of single camera video EEG is either to look at the general situation, or only to see the situation, can not simultaneously take into account.
The quality of video EEG is mainly determined by the three factors: the amplifier, the camera system and the computer system. Because the computer and camera hardware development is very fast, so the computer and the camera is not the key factor to determine the video eeg. The important factor that determines the video EEG is the anti disturbance ability of the amplifier and the computer software system of the EEG.
The number of leads is not the factor that determines the quality of video EEG. According to the clinical needs, scalp EEG in the outpatient department, and 32 digital video EEG is enough. In epilepsy surgery for invasive electroencephalogram (EEG) is much to lead multiple EEG, usually cases, 128 channel EEG can meet the needs of the general labor.
