Security engineering companies in the intelligent security monitoring system or product specific purchase, need to pay attention to the following points:

1. See if the product has passed the quality certification

Security engineering companies to buy products, first of all to see whether it is a qualified product through quality certification, can meet the requirements of electromagnetic compatibility EMC. Can not be greedy for cheap and choose no quality certification products, otherwise not only the project can not pass the final acceptance, resulting in unnecessary waste, more importantly, delayed time, affecting safety.

2, foreign and domestic products are the same, choose domestic products

Security engineering companies in the purchase of products, first of all, should check whether the domestic security enterprises have corresponding products to meet the demand, if the domestic does not meet the needs of intelligent functional products to buy foreign products. If the performance of domestic and foreign products is equivalent, the products of domestic enterprises should be purchased to support and promote the development of domestic national enterprises.

3. Domestic independent intellectual property products are the same as imitation foreign products, and independent intellectual property products are selected.

Security engineering companies in the purchase of products, but also to see whether it is independent intellectual property rights or imitation of foreign products. If the performance of the two is roughly the same, we should try to choose products with independent intellectual property rights to support and promote the development of domestic security.

4. See if the product has been intelligently evaluated and identified by experts, and can be evaluated and verified by itself.

Security engineering companies in the purchase of products, we must see whether it has been through the expert's intelligent assessment and identification. Even if there is a relevant expert evaluation and appraisal certificate, it is necessary to confirm its authenticity online, and then select it appropriately according to the standard grade range of its evaluation and appraisal.

5, the system product interface should be compatible with each other to meet the requirements of national standards, and easy to integrate and expand.

Security engineering companies in the purchase of products, we must pay attention to the entire system product interface to be compatible with each other and meet the requirements of national standards, so that the system integration expansion. Because each unit is in the development stage, the construction of the security monitoring system must consider the future integration and expansion.
