How to choose manufacturers in the security market price fluctuations?

With the use of security inspection machines more and more widely, the security inspection machine manufacturers on the market are constantly increasing. Many manufacturers are occupying the market with price. Many users do not know how to choose manufacturers to buy? I watched this house and looked at the house again, but my heart was always without a bottom. Now the eye-eye security check for everyone to summarize the purchase suggestions.

First, the parameters are preferred:

In the current market situation, regardless of the size of electronic products, the competition of parameters is inseparable. In the security inspection product industry, some manufacturers flaunt the parameters of their own products, the penetration is high, the cargo conveyor belt is negative, due to technological development. On the other hand, this is understandable, because product technology is indeed a little bit better, but with these tiny parameter advantages to mislead consumers, this behavior is not worth promoting in the whole industry.

Second, the company set the time priority:

For those newly established sales companies, they need to be carefully considered, because they do not have the ability to take high risks, and the after-sales service is good, and it remains to be tested. But it is not the sooner the company is established, the better, or the sooner the company is established, the better, no absolute, the key is to identify and examine.

Third, the case customer priority:

If a security checker manufacturer can't provide their user list, it can fully explain their lack of strength. If possible, the seller can provide the customer case contract. It depends on whether the security equipment provided by the seller has a qualified test report or certificate. This is the quality of the product you want to purchase, and does not include related after-sales service.
