What's the use of store surveillance security?

For small and medium-sized shops, the security system is mainly based on monitoring and anti-theft, and the security system is relatively more complicated because the crowd is complex and the monitoring area is wider than the home. But compared with other large-scale security systems, the security of shops is relatively simple. Then, how to arrange the monitoring and security of shops? 1. What's the use of store monitoring security?

For the store's security system, monitoring mainly plays the following roles:

1, commodity loss prevention: install a fastball camera in the area of valuables and easily lost items, and monitor these areas 24 hours a day. The system can monitor one or more areas within the monitoring range. Once important items are moved or taken away, the system will immediately send out alarm information such as sound and text in the CCTV monitoring room, and at the same time start high-definition video recording, which can better guard against theft and play a certain deterrent role. Even if the goods are lost, the video materials can be queried and played back in time through the DVR system of the branch company, and the video materials can also be provided to the public security organs to solve the case. For the undesirable elements who often go in and out of shopping malls, they can be printed out through DVR system and posted internally for employees' identification. At the same time, with the assistance of DVR, the number of security/loss prevention personnel in the store can be appropriately reduced, thus reducing the labor cost.

2. Supervision and management: Through the DVR system, the employee's work image and the goods in the store can be displayed at a glance. Managers can more reasonably co-ordinate the deployment of personnel positions in all districts of the store, assess employee performance and correct employee service attitude.

3. Statistical analysis of data: Through DVR system, you can check the flow of people at the entrance and exit of the store, check the buying habits of customers and the best-selling degree of goods, and also check the location and quantity of goods in order to replenish goods in time. Through video data and video intelligent tracking analysis, we can also understand customers' walking habits, so as to put the most commonly used and best-selling goods in places where customers can easily obtain them.

Shops generally do not have a professional engineering department, and users have limited knowledge of the security industry, so the system is required to be very simple and easy to operate. First of all, in terms of products, chain stores need some highly integrated products, such as built-in microphones and pickups. When there is a dispute with a customer, not only the video at the time of the dispute can be played back online, but also the audio information at that time can be restored, which is conducive to solving the dispute more effectively. At the same time, after adding the sound factor, the shopkeeper can understand the working status of employees more intuitively and comprehensively. The connecting line should also be standard wiring, preferably plug and play, without complicated wiring by users.

A small convenience store is generally equipped with about 2-4 cameras, which are installed in key areas such as cashiers, entrances and exits, shelves, warehouses, etc., and are basically installed in the corner with the widest viewing angle. As for the choice of bolt machine or ball machine, it mainly depends on the specific situation in the store, but we should pay attention to the overall style in the store.

Second, the anti-theft alarm system

From the way of detecting signals, the anti-theft of shops can be roughly divided into radio system, electromagnetic wave system, microwave system, frequency division system, intelligent system and acoustic magnetic system.

1, acoustomagnetic system

The tuning fork will only cause * * * vibration if the oscillation frequency is the same. Acousto magnetic system has realized almost zero false alarm operation by applying this physical principle. When the acousto-magnetic system tag fixed on the commodity enters the detection area of the system, it will generate * * * vibration, but it will give an alarm only after the receiver receives the * * * vibration signal for four consecutive times (once every 1/50 seconds).

Acousto-magnetic system is characterized by high anti-theft detection rate, almost zero false alarm, good anti-interference, and the width of protection exit can reach 3.5 meters. There are two kinds of anti-theft labels, which can protect most kinds of goods in shopping malls and can be degaussed repeatedly. Even at the POS cash register, the system can still work normally.

Acousto-magnetic system includes vertical system, channel system and concealed system. There are many models of 10 to choose from, which can be widely used in department stores, supermarkets, specialty stores, video stores, grocery stores, pharmacies and office buildings.

2. Radio system

Radio frequency (RF) uses radio waves as transmitting and receiving signals, and detects electromagnetic waves with a frequency range of 7.4-8.8MHz, with a center frequency of 8.2MHz, and the tag generates interference at 8.5MHz, thus triggering an alarm.

The biggest advantage of wireless system is its low cost and convenient installation. However, because its anti-theft tag is a ring coil type, the system is easily disturbed by some items, such as electronic products such as cash registers and metal objects. , resulting in false alarm or no alarm.

The radio system has two kinds of labels, soft and hard, which can protect most items in shopping malls. The distance between the two brackets is generally not more than 0.9 meters, which is usually used in shopping malls with only one entrance and exit. There are two kinds of radio systems, vertical and tunnel, which are used to protect department stores, clothing stores and supermarkets.
