How to maintain a biometric system?

There are many users of biometric system. Some use it in such a way that its shelf life exceeds a decade, the others damage it within just a few years. So what does help you prolong the longevity of a biometric system? Let's us educate you. There are some precautions that you have to take.
Don't clean the dirt buildup with an alcohol-based or a gasoline-based cleaner. The prohibition is even more important for a better performance of sensor. The abrasive cleaning agents make the layer of silicon on the sensor cloudy and lead to a poor performance. You should rather buy a mild ammonia-based cleaning agent.
Maintain the biometric system every three months at least. Longer interval can lead to short circuits in the hardware due to moisture condensed. The moisture is one more threat to the product life of the biometric system. The moisture trapped in the sealed packaging of the system causes product failure quickly. What can be done to maintain the integrity of the machine, then? Before making a purchase, try to know if the assembly was done in a controlled environment. Ask the buyer to what extent the packaging is permeable to moisture.


You should use a proper desiccant solution to avoid moisture. Make sure there is not any defect through which the moisture can pervade the desiccant.
If the biometric system is installed outdoors, the metal housing should be affixed.
The case is more appropriate for the lonely premises. Out of hours anybody may intrude in the building and tamper with the machine.
As shown in the picture below, the area sheet of plexiglass covering the sensor can be cut to allow the enrolled fingers to punch in.

Dust deposited on the hardware can be wiped out with a soft cotton piece of cloth.  The detergent can be used to clean the sides of the biometric system. If the dirt particles are big and obvious enough, lift up the front part of the hardware and remove the dirt particles.
