At present, all parts of the country "skynet project" building and construction is underway, "skynet project" construction is to build the information, the urgent need of prevention and control system is by party committee, government attaches great importance to the "party", "peace", "ZongZhi project". Skynet project covers the city and part of the town's main roads and intersections, party and government organs, financial system, large and medium-sized institutions, complex densely populated places, commercial areas, large entertainment venues, large commercial establishments, in and out of the city public security bayonet, in areas such as the basic form of urban street in jurisdictions all-round monitoring.

Monitor poling as carrying all kinds of cameras, alarm, such as the fill light parts of the main body, is mainly composed of poling, connecting flange, modelling of arm, installation of flange and embedded steel structure. There are two kinds of commonly used in the form of video monitoring poling: cone tube rod and two level straight rod. Taper pipe poling relative to the two-stage column tube stud has the following advantages:

Production process is simple.Cone tube of poling often USES the steel plate curly and straight on the welding process, welding precision almost no requirement, beautiful and reliable welding, weld does not directly stress at the same time, durability, reliability is high. And two-stage column tube poling need in different degree of welding a transfer between two levels of straight pipe pieces, higher requirements of welding technology, welding precision is not high to produce straight up and down axis direction inconsistencies and there was no question of overlap, and weld directly bear the gravity of the superior straight pipe, welding quality is not high easily lead to hidden trouble.
