How to determine the quality of the fingerprint lock?
1. Look at the material: The material of the fingerprint lock is basically three kinds, which are plastic, zinc alloy, stainless steel, including plastic durability, fire resistance, explosion-proof performance, followed by zinc alloy, stainless steel. Be
2, look at the appearance: The fingerprint lock of the three materials seems to be almost the same, which is attributed to modern plating technology, which can electrically plated different materials into materials like metal, but plastic fingerprint lock surface general surface Smooth, bright color, and zinc alloy slightly rough and a little color, stainless steel is the most rough and different color. Be
3, Weighing: If you use "see" and "knock" in two ways, you can determine the bracket or drop of fingerprint lock materials, you can use a simplest, most useful method to measure, ie "Baseline", we all know Light or heavy three materials, even if the internal plastic lock components are sufficient and zinc alloys or stainless steel still have a difference, one phase modulation is well known.
Be
4, knock: If it is difficult to "see" fingerprint lock material, we can use "knock" to judge, gently tap the lock body with your fingers, if the voice is not clear or empty, then in general plastic products It's not easy, stainless steel fingerprint locks are more clear focus. There is no much diffusion and penetration, and the sound given between zinc alloys is sharp, not stainless steel but pure fresh, more than plastic products . Be
5, test function: The "test function" here refers to the test of fingerprint lock, fingerprint lock, password lock and magnetic card lock response speed and accuracy. First, test the response speed and accuracy of fingerprint unlocking, please enter you first Fingerprint, which is also a step of verifying the fingerprint lock function. When the fingerprint is recorded, please observe the difficulty of the recorder record the fingerprint. If you can't identify the fingerprint after a few times, you can almost determine that the resolution of the fingerprint lock is not high. After the fingerprint is recorded, the random test locks its identification and response correct fingerprint. ability.
The faster the response, the better the lock performance, and like it can quickly identify the true fingerprint. Then accurately accurately, and vice versa, when testing, it is best to try multiple times, you can better identify advantageous disadvantages. Be
The above is about how to judge the quality of the fingerprint lock, if there is anything you don't know how to communicate with us, we will serve you wholeheartedly.
