PC Security Lenses
Problem Phenomenon
[Problem Phenomenon] Security surveillance lenses require high transparency, impact resistance and weather resistance
Cause Analysis
PC surveillance lenses are impact resistant and transparent, preventing vandalism; outdoor units require weather-resistant coatings; optical quality ensures imaging; when troubleshooting on site, verify each item according to this mechanism one by one, and avoid blindly adjusting the machine based on experience alone
Solution
Select optical-grade PC for surveillance lenses; outdoor coatings for weather resistance; surface hardening to prevent scratches; after adjustment, take samples continuously to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes, so as to locate effective measures
Key Takeaway
PC surveillance lenses are impact resistant and transparent, durable for security; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
