Top 5 CCTV Problems in Penang (And How to Fix Them)
Is your security app showing a "Device Offline" message? In Penang, high humidity and coastal salt air (Batu Ferringhi/Tanjung Tokong) can quickly damage surveillance hardware. Here is how to fix the most common issues.
01. Black Screen / No Video
Common in Bukit Mertajam & Butterworth
The Cause: Power supply failure due to lightning surges. The Fix: Replace the power adapter (approx. RM30–RM50).⚡ Pro-Tip: Install a small UPS to protect your system from Penang's heavy thunderstorms.
02. Blurry Night Vision
The Cause:
Condensation or IR light reflection.
The Fix:
Clean with microfiber. If the fog is inside the glass, replace with an IP67-rated camera.
