For “Shenzhen rental house video access control alarm system project” Delongsi Chuang launched a more advantageous single-door solution
Based on the construction design and maintenance experience of a large number of projects in the early stage, Delongxichuang has specially launched a more advantageous single-door solution to achieve simple construction, convenient maintenance, saving construction materials and labor costs. Strong low-cost support, making it more cost-effective.
The rental house monitoring access control alarm system is based on years of technical research, landlord demand analysis and public security business discussion, using the second-generation ID card, residence permit identification technology, remote network digital video technology, remote access control technology, remote alarm technology and computer Network software technology, a high-tech security system specially designed and manufactured for rental houses. The system not only satisfies the safety and living needs of landlords and residents, but also provides business support for the public security department. It is an integrated system integrating access control system, monitoring system, alarm system and special public security business system.
In order to cooperate with relevant departments to strengthen the comprehensive management level of social security and enhance the ability of public security to crack down on prevention and control, Delongxtron requires the promotion and construction of Shenzhen rental house videos with functions such as access control, video surveillance and alarm in places such as rental houses in urban villages in Shenzhen. The access control alarm system realizes the strong police of science and technology, improves the management level of rental houses and the management level of floating population, and at the same time improves the security and prevention capability of rental houses, reduces the incidence rate, and enhances the means of solving cases. Complete functions, strong practicability, easy operation, easy expansion and upgrade, and convenient maintenance, etc., according to the construction experience of a large number of projects in the early stage, a single-door network video access control project solution is specially launched, which greatly facilitates on-site construction wiring and later maintenance. The project operation cost is reduced, so that the rental house video access control project can be operated.

system structure
The rental house video access control alarm system is a set of systems that can operate independently and networked, that is, the monitoring access control alarm system of the rental house, and the data acquisition system of the public security part.
The rental house monitoring access control alarm system has two functions. The first is to provide a set of electronic security means for the rental house, which is convenient for landlords, tenants and public security joint defense, and can also provide integrated data collection methods for the public security department. The overall system structure is shown in the figure.
Overall structure diagram of rental house monitoring access control alarm system
As can be seen from the figure, the system is divided into four parts, which are described as follows:
1. Basic system
The basic system is that the rental house system and the community monitoring system constitute an independent operating system, which can realize door opening by swiping card, video monitoring and alarm system.
2. Management center system
The management center system completes the functions of floating population data collection and rental housing intermediary services.
3. Public Security Bureau System
The Public Security Bureau has completed the management of floating population, management of rental houses and online pursuit of escape. These systems have been completed by the Ministry of Public Security and are running systems.
Overall system design
Basic system design of rental house
The system structure installed on the first gate of the rental house is shown in the figure.
As can be seen from the figure, the basic system of the rental house, the front end is composed of access control controller, card reader, electric control lock, camera, optical transceiver, alarm device, power supply and other equipment. The management center consists of computers, hard disk video recorders, optical transceivers, switches, card issuers, readers, liquid crystal displays and ADSL networks.
The video signal of the camera and the data signal of the access control controller are transmitted to the management center through the optical transceiver.
The networking between the rental house and the monitoring center belongs to the category of local area network, and the existing line resources of the village can be used. The biggest feature of this system architecture is that there is no operating cost and no need to pay for networking.
2 Overall design of front-end video access control for rental houses
There are more advantages in the entire solution architecture. The specific advantages are as follows:
1. The voltage of the electric lock is stable and the system stability is improved:
Electric lock is the most “troublesome” kind of lock among all locks. The instantaneous change of current when unlocking is very large, which can easily affect the stability of other equipment or lines. When using a single-door controller, the length of the power cord of the electric lock is two or more. Meters or so, the voltage of the electric lock is stable, and the scope of interference with other equipment and lines is greatly reduced, thereby improving the reliability of the system;
2. Save the labor cost of wire and wiring:
Card readers, electric locks, door sensors, exit buttons, and warning lights are all near the control box, and the wiring distance is short. Except for the network cable that needs to be routed through outdoor pipes, other lines do not need to be routed through outdoor pipes, which can save a lot of wire and wiring labor costs; Furthermore, if the access control points are scattered, the advantage of a single door is more obvious.
3. Convenient debugging and maintenance, saving debugging and maintenance costs:
The front-end equipment of each door is put together, and the system debugging is intuitive and simple, which is more conducive to finding the cause of the fault.
4. The single-door network controller can work offline. After a long time, even if the outdoor network cable is abnormally disconnected, the single-door network controller can still open and close the door normally, and the system has good robustness.
5. The risk of failure is relatively much smaller:
Assuming that the controller is damaged, the multi-door controller may cause multiple doors to fail to open, and the single-door controller can only open one door at most, and the risk of failure is relatively small.
6. Using a single-door network controller, there is no special requirement for the wire, and the requirements for the power supply and other equipment are also very low. The ordinary wire and the commonly used 3A access control power supply can be used. After the battery is powered off, the persistence time will be longer.
