The system has been installed and used in 45 prisons in the United Kingdom and has begun to be promoted throughout Europe. The main purpose of installing the system is to prevent prison keys from being taken out of the prison. For prisons, the key is very important. Take out of the prison, for the security of the prison, all the keys and locks of all the doors of the prison must be replaced. This will cost a lot of financial, manpower and material resources, and will also affect the normal work of the prison.
The solution is to ensure that each key has a TC4S proximity card, which is permanently fixed on the key ring to ensure that the proximity card and the keychain are not artificially separated. The professionally designed TC4S is sturdy and wear-resistant and has a long service life. It is suitable for fixing with a large series of metal keys. The key ring of the induction card is embedded with a steel ring, and the entire electronic part is sealed with epoxy resin. Each proximity card has a unique ID number, and each staff member has a metal sign of his own, with the staff number engraved on it. When the staff comes to the key collection area, they must first carry the metal Give the sign to the key clerk, and tell the clerk his name and number. After the clerk has verified that they are correct, take out the keychain belonging to the staff member from the corresponding key cabinet and place the keychain close to the EC1A card reader for easy access. The card reader reads the ID number of the proximity card carried on the set of keys, and transmits the ID number to the system (computer) via RS232. The system immediately has three actions:
A. The personal information of the staff corresponding to the ID number is found from the staff database and displayed on the computer screen, so that the key keeper can confirm whether the personal information stored in the computer is the same as the visitor, such as photos and gender , Age, metal tag number, etc.
B. Record the time to pick up the keys.
C. Start the surveillance camera to capture real-time images of key pickers and archive them for later analysis.
EC1A card reader has a built-in buzzer. The buzzer will beep once every time the card is read. If the buzzer cannot beep and the red indicator light flashes, it indicates that the battery voltage of the proximity card is low, and the card needs to be replaced in time (low battery phenomenon).
When the key is returned, the custodian will show the returned keychain in front of another EC1A, so that the system can record the key return time, and then find relevant information from the database for comparison, such as: the returned key corresponds to the key cabinet Location and relevant personnel’s metal tag number, and whether the person returning the key is the holder of the metal tag.
In order to prevent the key from being taken out/into the prison, a CR1A reader is installed at the entrance and exit of the prison. The commonly used card reader is CR1A-MS, which can connect two external antennas and each antenna can be made into a stainless steel bracket. Beautiful and sturdy (pictured below). The card reader is equipped with a relay, which can be used to drive an alarm (horn), so that when the keychain is brought into prison, the card reader will sound an alarm after reading the proximity card on the keychain. (The purpose of installing a card reader at the entrance of the prison is to prevent the key from being taken out of the prison and copied by the bad guys and then brought back into the prison to avoid inspection by the prison management.
If the prison exit channel is more than 1.2 meters wide, we recommend the CR1A-DS-MS card reader, which can be connected to four antennas, divided into two groups of master/slave antennas, two of which are in the form of stainless steel antennas. ) Installed on the left and right sides, and the other two antennas are installed on the ground. This structure is often used to monitor the entrance of the vehicle, but it should be noted that the proximity card in the vehicle cannot be identified. The solution is to use a handheld card reader ELC-W, which can provide a reading distance of 1 meter, the card reader is equipped with a strong rechargeable battery, the continuous working time is up to 8 hours, the staff can hold this kind of reading The card device detects whether there is an induction card in the car.
On the basis of the above system, the following applications can be added according to actual requirements:
1. Fix a proximity card on the prison valuables to prevent the valuables from being taken out of the prison.
2. Install card readers in main places of the prison for personnel tracking and prison key tracking, such as near the cell where special criminals are held or near the prison hospital.
3.The staff holds the card for dining, attendance and other all-in-one cards
4. Family members of visitors (visitors) are issued cards when entering prison, and the cards are taken back when they leave prison, so as to track the situation of family members (visitors).
