Performing Stringent Inspections, Using Quality Materials
We conduct long time aging tests. For main boards and IR boards, the test lasts for at least 120 hours under the temperature over 50 degree Celsius; and for finished goods, we double-test them for another 120 hours under the temperature over 50 degree Celsius.

We use good secondary materials for cameras, such as IC chips, LEDs, transistors and capacitance, which are from Rohm, Toshiba and AVX to ensure the highest quality. Moreover, all our cameras use high-quality crystal filters to secure clear, crisp image and color.

With over 10 years of experience, it is easy for our skilled engineers to solve most of the technical problems. Also, we always buy the similar cameras from our competitors, test and compare them with ours, and then we make improvement and update our items.
