Description

technical field [0001] The invention relates to a monitor, in particular to a monitor with a single magnetic head partition wall. Background technique [0002] Due to the needs of criminal investigation, the monitoring of criminals is very important and one of the necessary means. To improve the anti-investigation ability of criminals, more advanced equipment and technology are needed. The existing monitoring equipment is too bulky, and the probe needs to be in stable contact with the wall during monitoring, and the monitoring effect is also related to factors such as the thickness and material of the wall. The use accuracy is not high, and it cannot meet the present needs. Contents of the invention [0003] The object of the present invention is to provide a simple and fast single-head partition wall monitor with superior performance and can be used in different occasions in order to overcome the above-mentioned defects in the prior art. [0004] The purpose of the pres...
