In today's prevalent usage of surveillance systems, camera malfunctions have become relatively common occurrences. To equip you with practical know-how, we've compiled a comprehensive list of twelve maintenance techniques for surveillance cameras. These insights are purely informative, so don't hesitate to bookmark them if you find them valuable!

1. **Voltage Detection and Isolation Method**

2. **Voltage Detection**: Assess critical points within the circuit by measuring voltages to identify potential fault locations.

3. **Isolation Method**: Use this technique to narrow down the faulty area in the circuit when short circuits or excessive currents are detected.

4. **Resistance Detection Method**: Determine the functionality of specific circuit components by assessing their resistance.

5. **Current Detection Method**: Analyze current values to diagnose faults accurately.

6. **Visual Inspection Method**: Preliminarily inspect the circuit for visible signs of damage caused by factors like burning or explosions.

7. **Experience-Based Approach**: Leverage past experiences to pinpoint potential fault locations.

8. **Substitution Method**: When unsure about the condition of a component, replace it temporarily with a known working one to verify its functionality.

9. **Adjustment Method**: Fine-tune settings using potentiometers or other configurations when product values deviate from standard parameters.

10. **Induction Method**: Introduce interference signals at the output terminal to pinpoint faults accurately within specific sections of the circuit.

11. **Temperature Method**: Address intermittent issues occurring after a period by applying controlled heating to identify and resolve the fault.

12. **Touch Method**: Open the casing and use your hand to touch components (chips) for excessive heat beyond normal temperatures. If the component is abnormally hot and you cannot comfortably keep your hand on it, identify it as a potential fault.
