Foreword
High-speed dome camera is an integrated monitoring and control product integrating electronics, motors, machinery, arts and crafts and other multi-field technologies. It was born, and in technology and application, it has had a great impact on the security monitoring and control reform. Whether it is the structure, the movement or the drive motor, it is the result of precise calculation and design. In particular, the HD HD 360° unlimited rotation is a major technological breakthrough in monitoring. Such monitoring equipment has unique requirements in construction and installation, and some matters needing special attention should be understood. Next, this article allows us to discuss its installation and construction requirements.
High Speed ​​Dome Camera Pre-installation Ont
Due to its special body and circuit structure, high-speed dome cameras must be well-understood when installing and installing high-speed dome cameras. First of all, after getting high-speed dome camera equipment, you must first do the following checks:
1. Check whether the packaging of the equipment is in good condition. As the packaging and protection methods for this kind of high-speed dome camera are usually required to be high, there are still cases of poor packaging and protection; in addition, before the installation of the high-speed dome camera, due to packaging impact The resulting loose parts can also occur.
2. Check whether the back cover arc of the high-speed dome camera is deformed. This is often the case before the installation of the body, because the fuselage rear cover deformation and the camera itself is not enough tightness.
3, check the transparent acrylic cover has scratches, deformation? This is a picture quality variation caused by unclear or counter-refracted light caused by poor acrylic cover.
4. If it is an outdoor high-speed dome camera, you must first check whether the waterproof tape between the cover and the acrylic transparent dome cover is hardened. Is the elasticity intact and does the infiltrated oil on the top of the waterproof strip and in the fixing groove remain moist? This will affect the outdoor waterproof performance of high-speed dome cameras.
5, before installation, please try high-speed dome camera cover and back cover assembly when the degree of tightness and screw engagement is smooth and no collapse, in practice, the emergence of water in the fall or the fog of the dome is generally this It is caused by the lack of airtightness.
6. Whether there are broken lines and creases in the high-speed dome camera's internal movement and the circuit-connected flat cable (Rabincable). This part should pay special attention to the inspection, because often there is no image or the zooming of the lens occurs after the camera runs for a period of time. Failures such as no action are caused by the loss of the flat cable during assembly or poor pin joints.
7, high-speed dome camera is usually attached to the connection line of the joint line, here contains the image BNC coaxial or RJ-45 network cable connector, three-core power cable, alarm connection line, I / O external control line and the knot First of all, after these short lines come out of the camera body, we must inspect two things: First, if it is an outdoor device, check whether the camera outlet has a waterproof connector, and whether the gasket and apron of the waterproof connector are flat and undistorted; Whether the connector of the splicing cable attached to the device is attached, whether it is loose, and the length of the short line, these will affect the quality of the entire project during installation.
8, but also check the high-speed dome camera internal cooling fan and heating defogger circuit, which is the focus of the camera body should pay attention to, especially in the construction before the actual detection of these circuit contacts and joints are solid. Poor electrical connection may cause short circuit or disconnection, which may cause loss of heating, defogging, or heat dissipation, resulting in camera damage.
9. In the high-speed dome camera, there are many ways to block the movement in the base of the high-speed dome camera. There are a single cassette and double cassettes, there are plastic cassettes and metal cassettes, no matter what the style, in the construction Must be implemented before installation to check its firmness and spring elasticity. Often when a high-speed dome camera is in operation, the movement is detached from the enclosure due to this part of the defect.
10, high-speed dome camera horizontal and vertical rotation with direct motor drive, belt drive two, in particular, need to pay attention is that the majority of the belt drive, before installation may wish to take up the movement and pressure level and vertical drive belt, if too Loose or too tight will cause the camera to rotate up and down and left and right to produce unsteady shake. This is also a very important test item before the installation of a high-speed dome camera.
The above are the necessary precautions and inspection item descriptions for the camera body before the installation of the high-speed dome camera. It should be noted that the location where the high-speed dome camera is usually installed is not a commanding height or a special environment, if there is a camera body Too many problems arise, it will certainly make the engineering company go up and down when installing, and it will affect the construction time and quality.
High Speed ​​Dome Camera Installation
As mentioned earlier, the high-speed dome camera is a product with a special installation location. Therefore, there will be some conditions and constraints in the installation and construction details that are different from those of a normal camera. Therefore, we are working on a high-speed dome camera. When installing, it is inevitable that there will be some rules that must be followed and followed. Let's also explore the key points of installation.
1. The cable connection of the high-speed dome camera must be performed cautiously: Because the high-speed dome camera is usually installed in a space above a certain distance, the position is high and maintenance is not easy. The lead wire and the main cable are connected to the wire line or the connector is connected to the two Ways. In line docking, we often see engineers tying the bare copper wires at both ends and wrapping them with electrical tape. Some engineers will use the sealing terminals to wrap the second wire in the terminal to prevent it from falling off. But personally feel that a better way is to connect the two-wire end by welding and then cover the heat-shrinkable insulation bushing. This is a time-consuming, labor-consuming and cost-increasing way, but think about it. Follow-up maintenance will be no worries, this approach is still worthy of adoption.
2. When the high-speed dome camera is connected to the cable, if the connector is docked, for example, after BNC, 3.5mm Jack docking or pinpinin docking, the connector must be fixed with electrical tape or heat shrink tubing. Only after a certain period of time does the joint loosening event occur after application, it is even more important to note that when the screw is crimped, the end of the wire must be soldered and plated to increase the resistance against slippage and conduction during crimping. Sex.
3, high-speed dome camera indoors, the cable outlet must have a certain export guide, especially the plane ceiling fixation, do not press the cable directly to the base, otherwise it may be in a period of time because Thermal effect or line conductor skin effect causes wire breakage or short circuit caused by heat softening; indoor installation embedded in the ceiling should pay attention to the placement of the 24V power transformer and the spacing from the lighting high-voltage power supply, which is usually a sloppy installation practice will lead to unprocessable Image power harmonics interference.
4, the installation of outdoor high-speed dome camera should pay particular attention to the problem of the water guide of the fixed bracket, many engineering companies when installing a high-speed dome camera, often installed in a higher position than the cable junction box, in the camera When the end line enters the junction box, it does not enter the line or is waterproofed vertically below the junction box. As a result, rain often occurs as the tail pipe passes through the hose and enters the junction box (case). Light causes a short circuit. At worst, transmission and camera equipment are damaged.
5, high-speed dome camera installation should not be close to steam or heating and air conditioning outlet, it is easy to cause condensation, making the camera dome cover water and water mist for a long time can not disperse the situation.
6, high-speed dome camera must be installed in the installation should not be installed behind the street lights or lights, often because of this construction method to high-speed dome camera brings a reflective glow and a transparent cover to produce a light arc, affecting the camera screen Full presentation.
7. The outdoor high-speed dome camera must do a good job in the line grounding and power grounding. We often see the consequences of not doing earthing in the high-speed ball engineering installation, that is, after the power surge generation, power failure, After the restoration of power supply or a thunder, high-speed dome cameras can no longer continue to operate.
8. When the high-speed dome camera is installed outdoors, the screw bite of the fixed frame must be lubricated and grease protected. At the same time, galvanized steel pipe or stainless steel should be used on the material to ensure the smooth disassembly of the weathering, follow-up warranty and maintenance work. .
9. When the high-speed dome camera is installed, regardless of the indoor or outdoor environment, the safety cable or the fall arrest device on the movement must be installed and executed to avoid the fall of the dome cover when the maintenance is disassembled. It should be reinforced with a safety cable on the surface of the concrete so as to prevent earthquakes and injuries.
10, high-speed dome camera usually has a communication protocol dial switch, start self-detection function, do not avoid the difficulty of installation dialing, dial switch is best set before loading the movement to avoid frequent removal Causes the detection action to frequently cause the preset action capacitor to discharge, causing a deviation in the default position.
Conclusion
The above ten points are important for the installation of high-speed dome cameras. It is a non-negligible precaution in engineering installation. The high-speed dome camera itself is a product that integrates motors and processes, and it can exert a great deal of monitoring capabilities in the range. There are advantages in terms of size and distance. If it can be installed in front of the project, high-speed dome cameras are definitely a perfect engineering art masterpiece.
