There are many times when users need to buy products, and when they get to the store, they are dazzled by all kinds of products. At this time, how to identify the quality of a product has become the buyer's most concern. Today, the editors will introduce to you the buying skills of the hemisphere surveillance camera.

The dome camera, as its name implies, is a hemispherical surveillance camera. The dome camera consists of a camera, an auto-iris manual zoom lens, an excellent sealing cap, and a precision camera mounting bracket. Its greatest feature is its compact design, aesthetics, and ease of installation.

In recent years, with the continuous application of security products in all walks of life, people began to focus not only on the monitoring quality of surveillance cameras, but also began to pay attention to factors such as whether it matches the housing renovation, whether it is convenient to install, and whether replacement parts are convenient. The hemisphere camera is designed for full coordination with the built environment, both beautiful and hidden, and it has been widely used in television monitoring projects.

Compared with the traditional bolt, hemisphere surveillance cameras have their own sophisticated protective cover and the characteristics of the mounting bracket, while the bolt need to configure the protective cover. This eliminates the hassle of assembly and makes it simple and beautiful. However, it is not that it is a product with no shortcomings. The dome camera comes with a zoom lens, but its zoom range is very small and the lens is not easily replaced. The gun casing itself uses different lenses for observation, with strong adaptability and high matchability. Based on this soft underbelly of the hemisphere surveillance camera, it is determined that it is only suitable for small-scale indoor surveillance.

However, with the development of technology, the camera function of the hemisphere surveillance camera has not been much different from the high-ranking bolt machine. At this time, the advantages of convenience, surveillance, and concealment are more prominent.

So what should you watch out for when buying a dome camera? First of all, attention must be paid to the reproducibility of the image because the lower dome is a sphere with a small radius of curvature, and its uneven thickness or poor polypropylene material production will seriously affect the image quality.

Next, look at the clarity, color reproduction, and sensitivity of the image. The dome camera is different from the bolt machine, although its various functions have been greatly improved, but the fact that the lens replacement is difficult is indeed indisputable. When purchasing, the user must firstly test whether the lens meets the monitoring requirements at the testing site, otherwise the lens replacement will be very difficult.

Finally, pay attention to the power supply mode. The dome surveillance camera adopts AC-DC adaptive or /AC (24VAC) power supply.
