Fine interior installation camera wiring诀窍

[ Huaqiang Security Network News ]
The camera of the camera is a semiconductor imaging device. Although it is small, it has the advantages of anti-glare, small distortion, long life, high sensitivity, anti-vibration, etc. Image generation is based on the current surveillance camera defense system. CCD cameras, so the safe installation of cameras has become a topic of concern, especially in terms of wiring. How to carry out indoor wiring? Listen to the author's suggestion.
Camera
When the camera is installed, the wiring of the conduit is available in both clear and dark configurations. The camera's clear piping requires horizontal and vertical, neat and beautiful. Dark piping requires short, smooth, and elbows. When wiring, try to avoid wires with connectors. Unless the connector is not available, the connector of the camera must be crimped or soldered, and the wire connections and branches should not be mechanically affected. The wires that are empty in the tube must not have a joint under any circumstances. If necessary, place the connector on the junction box probe terminal. The alarm from the camera alarm control box to the ceiling requires management to be installed in the wall or protected by iron pipes to improve the anti-destructive performance of the anti-theft system. In addition, the AC power should be routed separately, the camera cannot be connected to the signal line and the low-voltage DC power line. When worn in the same tube, the AC power cord should be installed in accordance with electrical installation standards. The signal line cannot be parallel to the high-power power line, and it cannot be worn in the same tube. If it is limited by the environment, it should be kept away from the line by 50cm. For the camera cable, the rated voltage should be greater than the working voltage of the line; the insulation of the wire should conform to the installation method of the line and the environmental conditions for laying. The cross-sectional area of ​​the wire should meet the requirements of power supply and mechanical strength.
Through the above steps to install, I believe that everyone will understand, I hope to help everyone.

7 Bars Led Grow Light

7 bars led grow lights is a special lamp to provide light for plants. It usually consists of seven light bulbs, each with a different color and wavelength to simulate the spectrum of natural sunlight. This light fixture is widely used in indoor planting and gardening.

The use of the 7 bars full spectrum led grow lights mainly depends on the following aspects:

1. Light time: plants need light for photosynthesis, and different plants have different needs for light. In general, most plants need 10-12 hours of light per day, so 7 bars plant lights are usually set to work 10-12 hours per day.

2. Light intensity: Plants also have different needs for light intensity. Some plants require more light, while others require less light. 7 bars waterproof led grow lightss usually have an adjustable light intensity function that can be adjusted according to the needs of different plants.

3. Distance and Angle: The distance and Angle between the plant and the 7 bars indoor grow light will also affect the lighting effect. In general, the distance between the plant and the lamp should be kept within an appropriate range to ensure that the plant can fully receive the light.

4. Types of plants: Different plants have different needs for light. Some plants need stronger light to promote growth and flowering, while others have lower light requirements. Therefore, when using the 7 bars indoor grow lights veg, it needs to be adjusted according to the type and needs of the plant.
