1. The wire used for the surveillance camera should have a rated voltage 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 of the laying. The cross-sectional area of the wire should be able to meet the requirements of power supply and mechanical strength.

2. When wiring, try to avoid wires with connectors. Except for the joints that are not required, the camera's joints must be crimped or welded, and the wire connections and branches should not be subject to mechanical forces. Under no circumstances should there be any connectors for the wires that run through the tube. If necessary, place the connectors on the terminal blocks of the junction box probes.

3. The wiring should be installed horizontally or vertically in the building. Wiring should be protected by bushings (plastic or iron pipes, optional according to the technical requirements of indoor piping). Metal hoses can be used for the ceiling wiring, but they must be fixed and beautiful.

4. The signal line cannot be parallel to the high-power power line, let alone in the same tube. If the environment is limited, you should run the cables in parallel, and keep them away from more than 50cm.

5. The AC power of the alarm control box should be routed separately. The camera and the signal line and low-voltage DC power line should not be put in the same tube. The installation of the AC power line should meet the electrical installation standards.

6. The wiring from the alarm control box to the ceiling requires additional management into the wall or protection with iron pipes to improve the anti-theft performance of the anti-theft system.

7. Conduit wiring has two types: bright and dark. The camera piping needs to be horizontal and vertical, neat and beautiful.

1. Turn on the automatic electronic shutter function of the camera

2. Use the controller to adjust the lens aperture to the maximum

3. Point the camera at an object 30 meters away and adjust the focus to infinity (most lenses are facing the lens and turn the front focus adjustment ring clockwise to the head)

4.Use the controller to adjust the lens zoom to push the scene as far as possible, and adjust the rear intercept of the lens to make the scene most clear

5. Use the controller to adjust the lens zoom to pull the scene, fine-tune the lens focus to make the scene most clear

6. Repeat 4-5 steps several times until the scene is always clear during the lens zoom

The Regulations of Henan Province on Public Security Technical Prevention Management stipulates that no unit or individual may buy, sell or view or copy the information collected and maintained by the computer room system without the notification of the public security organ. The videos posted on the Internet will face a fine of up to 30,000 yuan. The regulations also stipulate that the installation of monitoring facilities should be provided with clear signs to remind citizens to protect their right to privacy; at the same time, it is prohibited to install monitoring systems in places involving citizens' privacy.

Public security organs at or above the county level may impose fines of 5,000 to 30,000 yuan on units that violate regulations, and fines of 1,000 to 5,000 yuan on individuals.

1. Infrared hemisphere series machines have poor image illumination, whitening or bright white aperture at night.

This phenomenon is caused by improper assembly of the machine. When the photosensitive device (photoresistor) is too far away from the hemisphere during assembly, it will cause the infrared lamp to start incompletely and cause the machine to have poor illumination at night; the phenomenon of white or bright white apertures is mainly caused by the infrared light emitting tube The infrared light is refracted to the lens through the dome cover. The solution to this phenomenon is to avoid refracting the infrared light to the lens surface. Generally, the sponge ring is used to isolate the lens from the infrared light. When assembling, the dome cover must be close to the sponge ring.

2. The night vision infrared waterproof machine has normal images during the day and whitish at night.

This phenomenon is generally caused by the use of reflective objects in the machine's environment or in a small space, which is caused by the reflection of infrared light. To resolve this phenomenon, first determine whether there is a reflective object in the use environment, improve the use environment as much as possible, and then check the effective infrared of the machine. Whether the distance corresponds to the actual use distance; if a long-range infrared machine is used in a small space, the machine's image will become white due to the infrared light being too strong.

3. If there is no image, first check whether the polarity of the external power supply is correct and whether the output voltage meets the requirements.
), Then check whether the video cable is in good contact; if you use a manual aperture lens, you need to check whether the aperture is open. For an automatic aperture lens, you need to adjust the LEVEL potentiometer to make the aperture in a suitable position.

4. The color distortion and color cast may be caused by improper white balance switch (AWB) setting, or the ambient lighting conditions may change too much. At this time, you should check whether the switch setting is in the OFF position and try to improve the environmental lighting conditions.

5. The image is distorted or geometrically distorted. This phenomenon may be a problem with the geometric correction circuit of the camera or monitor or a problem with the optical lens, or it may be that the characteristic impedance of the video connection cable or equipment does not match the output impedance of the camera. When the above phenomenon occurs, please check whether the optical lens used is abnormal and the input impedance switch of the monitor is set to 75, and then check whether the impedance of the video connection cable is 75.

Focal length: The focal length of the surveillance camera refers to the distance between the lens and the photosensitive element. The magnification of the lens is approximately equal to

(1) Network Camera 11 (ordinary version) is a new generation of cameras produced by combining traditional cameras and network technologies. As long as the network camera is plugged into a network cable (no computer required), it can transfer images through the network To the other side of the earth. You can remotely control the camera by 320 degrees left and right, rotate 60 degrees up and down for monitoring, and record the monitoring screen, send it to the mailbox or

The security industry has ushered in a new era of digital surveillance, video surveillance platforms have also entered the fast track of development, and video surveillance equipment has begun to become intelligent and convenient. It is understood that the future development trend of China's video surveillance market is family and civilian. With the continuous improvement of the contemporary home network environment, the increase of consumer spending power, the enhancement of security awareness, and the increase in independent living households, domestic household civil monitoring equipment has quietly risen. In response to the user's needs, a new type of security monitoring equipment, a power network IP camera (English name: plugCAM), is developed. This type of monitoring equipment, known as a power network surveillance camera, is based on PLC technology and uses existing power lines Transmission of network video signals is a typical representative of the third monitoring method, namely power line monitoring. This product can bring ubiquitous monitoring services to users through technology fusion.

The power network IP camera consists of two parts. The front end is a 500M PLC bridge (you can also use the power cat PLC bridge with it). The smart camera terminal is a power network IP that integrates the 500M power cat PLC bridge function. camera.
