The surveillance camera is already a very widely used camera. So in the application and procurement of the majority of users, if the camera is broken, how can we repair the camera? So what about camera repair and surveillance camera repair skills? Below I will share with you the commonly used camera repair skills, for your reference!
1. Voltage detection and disconnection method.
2. Voltage detection method: used to detect the voltage of each key point in the circuit to judge the fault point.
3. Disconnect method: When there is a short circuit or excessive current in the circuit, use this method to reduce the fault range.
4, resistance detection method: used to judge the quality of a certain part of the circuit.
5. Current detection method: The fault is judged by observing the current value.
6. Observation method: Initially check whether the circuit is damaged by irresistible factors such as charring or explosion.
7. Experience method: judge the fault point based on past experience.
8. Substitution method: For components that cannot be determined to be damaged, use the substitution method to verify whether the suspect component is damaged.
9. Adjustment method: When there is a deviation between a certain value of the product and the normal product, it can be adjusted by potentiometer or other settings until the satisfactory effect.
10. Induction method: When there is no output or the output is unstable, an interference signal is added at the output end to accurately determine a certain component of the fault in a certain part.
11. Temperature method: When there is a failure after a period of use, the heating method can be used to eliminate the fault.
12, touch method: open the case, touch each component (chip) with or without overheating or exceed the normal temperature, that is, the hand can not stay on the component, it will feel abnormal heat and judge the fault point.
Flat Vacuum Light Box
Blister light box is a luminous light box composed of LED light bars and acrylic panels. It is characterized by its unique vacuum shape, more attractive than the LED light box symbol on the plane, and more three-dimensional.The blister light box adopts the three-dimensional luminous character processing technology. Due to the stable quality of acrylic, its products are characterized by good light transmittance, clear farsightedness, high compressive strength, colorfast for more than ten years, and bright as new, which are incomparable with other light boxes and metal characters. It is the best choice for businesses with sustainable business and strong strength.
The overall thickness of the flat acrylic lamp box can be thinner than that of the vacuum lamp box. It looks more exquisite and beautiful.
