Today's communities have all used the access control intercom system, which has brought convenience to the occupants but also brought certain troubles. How to buy a safe building intercom product? What problems should you pay attention to when installing? Please read this article!
Security building intercom purchase
1. Building Talkback System Design: When choosing a security building intercom system, you must ensure the buildability of the networked system! Design must be stable and reasonable! Isolation protection and fault information forwarding must be precise and fast! It must be required that the building intercom system has a multi-channel (or independent) alarm information channel! To ensure that the alarm information can be notified to the user or the security personnel of the management center at the fastest time! Secondly, the building intercom system must take automatic circuit inspections to detect the status of the equipment and wires in the network at any time! Prevent problems such as alarm messages that cannot be transmitted due to natural and human-induced faults!
2. The management center machine and the user indoor unit are the key: The management center machine must have the principle of multi-channel working at the same time. The alarm information at any time must be given priority by voice plus character! The voice prompts can alert the security personnel present at the scene; they serve the function of warning and reminding; the characters accurately display the alarm types and addresses and types, and the security personnel make correct decisions based on the alarm address and type of the police displayed by the management center. The processing method to avoid the loss of property; followed by the front-end equipment, indoor machine user machine can be made of performance! Indoor extension must have super stability! Stable operation at any time! Precisely distinguishes the working status of each police type! The indoor user's machine is easy to operate and can be withdrawn and armed at any time for each type of police.
3, the function of the corresponding equipment should be complete: the user indoor unit, the unit door host, the management machine must have withdrawal, arming management! And can quickly and easily remove the defense; building intercom system related accessories, must have the level of intelligence, can forward all kinds of alarm, fault information function, with superior protection!
4, the corresponding alarm detector: the corresponding alarm detector must have linkage alarm function (more on-site alarm function is better); alarm detector must be stable and reliable; to reduce false positives!
5, power supply management: As the network system has automatic inspection line function; detectors may be deployed at any time, disarm, ready to work! The source of the system's capabilities - the power supply must be stable and reasonable, with a variety of fault protection features!
6, the installation of equipment: equipment involves two aspects: First, the use of wire must meet the system design requirements! The second is that the installation of equipment must be strictly implemented according to technical requirements! Ensure that the installation of each alarm detector is reasonable; ensure that all wiring ports are firm; ensure that the corresponding building intercom equipment is installed stably and reasonably.
7, as long as the above problems are handled well! The realization of security-type building intercom is very promising!
From the project cost point of view: building intercom + home alarm = security intercom, choose security building intercom system is relatively cost-effective. This is also the reason why the building intercom system of the four defense areas or more defense areas is under the influence of greenery! As a building intercom industry insider, the security defense building now has a relatively strong security requirements. We don't want to have many functions. There are many alarm detectors and many are not necessarily practical. We must be reasonable!
Access control intercom installation focuses on issues
When installing an access control system, pay attention to the following three major areas:
First, prevent electromagnetic interference For readers, open the door button to pay special attention to anti-electromagnetic interference, especially lighting switches, electric typewriters and computers and other interference problems. If conditions permit, the reader should be installed at a distance of more than 30cm from the power source.
Second, to prevent the attenuation of the transmission signal The controller must be installed to take into account the distance between the controller and the reader, the ideal transmission distance is within 50m. For signal transmission cables, cable shielding and signal attenuation due to long-distance transmission must be taken into consideration. During the construction of the pipeline, the line pipe and cable tray made of steel should be used, and reliable grounding should be performed.
Third, the controller and system software debugging system debugging is to ensure the quality of the access control system, the key link. The focus is on the commissioning of the controller and the operation of the system software. The commissioning of these two parts must be carried out by the manufacturer at the same time. The function of the controller is to set the relay linkage output function according to the need besides the card reader input, the time and location of the alarm generation and start-up such as camera, alarm horn and so on.
Although the access control in the community facilitates the safety of visitors to the majority of residents and the security of vehicles, the disadvantages follow.
If there is no visible end in the household access control, the visiting guests will impersonate the identity of another person, such as X classmates or friends, courier companies, etc., so that the homeowner will open the door without protection. Therefore, it is recommended that the community's contractors use the visual access intercom system as much as possible to improve the security of the residents' access control.
For the vehicle access control system, some car owners will carelessly place the IC-type access control card in the vehicle instead of carrying it. This causes the thieves to have the same car card. Therefore, it is recommended that the card be stored separately and stored with the card. To improve safety.
Although the access control system is convenient to use, if you have problems and you want to find a contractor to carry out repairs, most people will not find people because of the huge profits in the current access control system. Although the real estate agent will not pay the access control contractors However, the contractor would rather not have the balance and will not perform maintenance and repairs. Because the line layout of the access control system is conducted from the ground, once problems occur, it takes a lot of manpower and material resources to carry out line excavation and troubleshooting, which is quite troublesome.
