Store anti-theft system installation should pay attention to the first one, identify the scene to eliminate the first time

In order to ensure the quality of the project, it is necessary to first investigate the source of the interference. If it cannot be eliminated, install the machine away from the interference source. There are two types of interference sources: the first is active interference, such as various spark interference, motors, hair dryers and sparks caused by poor contact, or interference caused by severe power clutter; The interference is passive interference, such as a coiled wire near the machine, a POS machine at the checkout counter, various signal lines of the printer, and whether the power line has a roll.

Shopping mall anti-theft system installation should pay attention to three, power precautions

1) Strictly grounding Some three-pin sockets do not have a grounding terminal. You need to re-pull a special line from the power distribution cabinet. This is done on the one hand in compliance with safety standards to avoid accidents; on the other hand, it reduces crosstalk in the power grid.

2) Guaranteed heat dissipation Because the system works for a long time, although the power box has sufficient power margin, if it is placed in a narrow or even semi-closed place, the temperature rise of the component too fast will affect the stable operation.
