In today's rapidly advancing world, the prevalence of surveillance systems has undoubtedly grown, paralleled by the occasional emergence of technical issues. In response, we've crafted an invaluable compendium featuring twelve meticulously curated maintenance techniques for surveillance cameras. This compendium is an embodiment of pure, actionable knowledge, an indispensable guide for anyone seeking to enhance the performance and longevity of their surveillance systems. Let's dive in!

**1. Voltage Detection and Disconnection Strategy**

**2. Voltage Detection Method:** This technique serves as a reliable means to evaluate voltage levels at key junctures within the circuit, thereby deciphering the precise points of malfunction.

**3. Disconnection Strategy:** When grappling with short circuits or excessive currents, this method proves indispensable in identifying fault locations. It's achieved by systematically isolating segments of the circuit to narrow down the potential problematic areas.

**4. Resistance Detection Technique:** Employ this method to ascertain the health of specific circuit components by gauging their resistance values.

**5. Current Detection Approach:** Employ this approach to assess the presence of faults by scrutinizing current values, shedding light on any irregularities.

**6. Visual Inspection:** Before delving into technical intricacies, a visual assessment is a preliminary step to detect telltale signs like burn marks or evidence of explosion-induced damage.

**7. Experience-Driven Approach:** Drawing from previous experiences can provide valuable insights into potential fault points, allowing for more targeted troubleshooting.

**8. Substitution Methodology:** When uncertainty arises over a particular component's functionality, the substitution technique comes into play. Replace the suspected component with a known working one to validate its role in the fault.

**9. Calibration Method:** When deviations from established norms occur, use adjustment mechanisms like potentiometers to fine-tune until desired results are attained.

**10. Inductive Analysis:** In cases of erratic outputs or instability, introduce controlled interference signals at the output end to pinpoint issues within specific components of a segment.

**11. Temperature Analysis:** For intermittent malfunctions that surface after a period of use, the temperature method can be applied. By applying controlled heat to various components, you can identify components that might be sensitive to temperature changes.

**12. Tactile Approach:** As a hands-on method, the tactile approach involves physically assessing components (such as chips) for unusual heating. If a component is excessively hot, implying abnormal functionality, this technique helps pinpoint fault locations.
