With the improvement of people's security awareness, people to the community access control system is not only limited to simple doorways and keys, but pay more attention to a complete set of perfect community access control system, to ensure the safety of the residence.So a set of reliable quality and durable access control system in the end how to choose it?

First, strong and durable

Ruthiness and durability can be said to be the most important condition of the access control intercom system, because first of all, from the functional point of view, access control intercom system is to protect the safety of the user's life and property, if even it itself is not strong enough, then how to talk about protecting others?Secondly, access control intercom system is the user in and out of the must pass through, use is extremely frequent, so often can hear the user complain about access control intercom system failure.

So how do you determine if a product is sturdy and durable?

It is suggested that users should try their best to consider the products of mature brands that are in the leading position in the world. On the one hand, they have typical users, and their quality has been tested a lot, and they have been highly recognized in the industry.Here Xiaobian can recommend some well-known brands, such as: Elem brand, Italian electric lock is the leader of the access control industry;Hikvision, Zhejiang Dahua, Honeywell are international large monitoring brands.

In terms of hardware, from the controller to the terminal identification equipment are mature and stable products.As the core of the system, the access control controller needs to support the off-line working mode, and must use non-volatile memory chips such as Flash, so that the information will not be lost when the power is off or the information is hit.The failure of server and terminal identification equipment does not affect the normal operation of the system

For many cases of human damage, in the selection of equipment should also pay attention to the product in the anti-human damage performance, such as whether it has anti-demolition alarm and other similar functions.

II. Compatibility

Users all know that there is not only one type of a large residential area, which may be integrated with multi-layer, small high-rise, high-rise and other different grades of residential positioning. Due to the audio and video coding and decoding algorithm, wiring standards, communication protocols, interfaces are not unified and the compatibility/standardization problem has been perplexing the buyers.In this case, multi-system compatibility of the device is required, so that different system requirements can be integrated according to different levels of the community, so as to adapt to different user needs.

So, in order to facilitate future upgrades, capacity expansion and anti-interference considerations, it is recommended to choose the terminal identification equipment in line with international standards, rather than the wider the compatibility, the better.Some formats have some advantages in the local, but do not meet the international standards, will be upgraded, expansion and anti-interference to bring trouble, should adhere to the practical, stable, in line with the standard principle.

Three, anti-interference design

Anti - jamming ability is a common headache in the building intercom industry at present.In terms of product quality, the anti-jamming capability is urgently needed to be improved, especially in some thunderstorm prone areas.In the field construction, improper selection of wire, wiring is not standard and so on will also lead to a variety of interference problems.Therefore, it is necessary to cause the universal attention of product suppliers and construction parties.

At present, the rated voltage of most building intercom gate power supply on the market is 220V, AC peak or synthetic voltage is 190-250V, and the test voltage of resistance to electric strength should be 1.5KV.To achieve this requirement, it can only meet the requirements of sudden changes in the circuit system, but it can not resist the attack of lightning overvoltage and super-large current.Therefore, the building intercom door should have lightning protection protector and grounding device good anti-static, anti-lightning, anti-leakage design, so as to avoid many problems in the later use of the product.

Four, humanized design

The access control intercom product is a product for the public, and the humanization of use is one of the most important characteristics.Humanized design here mainly refers to the humanization of the operation interface, including indoor machine, door machine, etc. For buyers, it is often children and the elderly use more, so the operation mode, the operation interface as far as possible the fool the better, such as: the operation process of language prompts, family messages, etc.;The screen graphical interface is richer, not just text prompts, etc.

As for this point, users in the purchase of products to understand more, after shopping around, choose their own like and suitable products.
