In order not to leave a dead corner, video monitoring devices should be installed in business counters, checkout counters, pedestrian walkways and other parts to achieve comprehensive coverage without blind spots. It is a wise choice to install video surveillance on the counters of shopping malls dealing in precious commodities, which has played a role in containment and prevention. The requirement for shop assistants is that they cannot produce two products at the same time, including specialty stores (independent stores) and counters (counters in shopping malls and supermarkets) of gold and silver jewelry stores. You can use the connection of the unit safety control room in supermarkets and shopping malls to install video monitoring equipment in business counters, pedestrian walkways and cashier areas to achieve no blind spots.

General video surveillance system uses digital hard disk video recorder as image recording equipment, which can record video images for 24 hours and keep them for at least 30 days.
