Release time:
Dec 20,2024
The monitoring pole, commonly referred to as the monitoring rod, is a cylindrical support used for the installation of outdoor surveillance cameras. Below is a detailed introduction to the monitoring pole.
1. Basic Concepts
The monitoring rod, in English known as Control rod, is mainly used for installing and supporting surveillance cameras for video monitoring. It is widely used in places that require surveillance cameras, such as traffic roads, residential areas, schools, government buildings, factories, border control, and airports.
2. Main Types
Monitoring poles can be classified into various types based on their shape, size, and application scenarios:
Octagonal monitoring pole: It has an octagonal cross-section, stable structure, and strong wind resistance.
Round tube monitoring pole: Made of round steel pipes, it has a simple appearance and is easy to install.
Equal diameter monitoring pole: The diameter of the pole remains consistent, suitable for places with specific height and diameter requirements.
Variable diameter monitoring pole: The diameter of the pole gradually changes from top to bottom, usually thinner at the top and thicker at the bottom to increase stability.
Conical monitoring pole: Shaped like a cone, thinner at the top and thicker at the bottom, it has good wind pressure resistance.
3. Structural Features
The monitoring pole typically consists of the following parts:
Main pole: Usually made of high-quality seamless steel pipes or galvanized steel pipes, it has strong pressure and wind resistance.
Cross arm: A horizontal bracket used for installing surveillance cameras, the length and angle can be adjusted according to actual needs.
Ground cage: A steel cage embedded underground to fix the monitoring pole and ensure its stability.
Pipe wall: The wall thickness of the monitoring pole is usually large to increase its wind resistance and load-bearing capacity.
4. Design Basis and Installation Specifications
Design basis:
Design wind load: Determine the design wind load of the monitoring pole based on local wind speed and direction.
Fatigue life: The design life of the monitoring pole is usually 30 years, and it must ensure that there is no fatigue failure during use.
Relevant specifications: Follow national standards and specifications, such as "Carbon Structural Steel", "Electrical Installation Engineering Cable Line Construction and Acceptance Specifications", "Steel Structure Engineering Construction and Acceptance Specifications", etc.
Installation specifications:
Foundation construction: Ensure that the foundation's steel cage is temporarily fixed, the top surface of the foundation is level, and pour dense concrete without voids.
Embedded part treatment: Seal the embedded pipe openings in advance with plastic or other materials to prevent blockage during concrete pouring.
Grounding of vertical poles: Each metal vertical pole must be grounded, with a grounding resistance of less than 4 ohms.
Maintenance and inspection: Cure the concrete for a period to ensure it reaches a certain installation strength; conduct a comprehensive inspection after installation to ensure there are no looseness or damage.
5. Application Scenarios
Residential areas: Used for anti-theft monitoring, with a height typically between 2.5 meters and 4 meters.
Roads: Including highways and regular roads. The height of monitoring poles next to highways is usually over 5 meters, with arm lengths between 1 meter and 1.5 meters; the height and arm length of monitoring poles on regular roads can be adjusted according to actual needs.
Traffic signal light poles: Serving as a common support for traffic signal lights and surveillance cameras, the main height is usually over 5 meters, with arm lengths up to 12 meters.
6. Other Special Types
In addition to the common monitoring poles mentioned above, there are also special types such as solar monitoring poles. Solar monitoring poles use solar panels to capture sunlight and convert it into direct current, providing power for cameras and batteries. This type of monitoring pole has a wide application prospect in outdoor monitoring work.
In summary, monitoring poles are important supporting devices for the installation of outdoor surveillance cameras, with certain professionalism and complexity in terms of types, structural features, design basis and installation specifications, as well as application scenarios. When selecting and using monitoring poles, comprehensive consideration should be given based on actual needs.
