  Protection	Protection class Video Video surveillance with a Zodiak camera is easy! Video Video recording from outdoor IP camera Zodiak 935W (1280x720P, street) Don't forget to set the appropriate recording video quality in the viewing settings :) Wireless technology makes life much easier. A striking example is modern video surveillance systems based on Wi-Fi devices. Outdoor IP camera Zodikam 3951-WPTZ (935W) (Rotary, metal, Zoom, WiFi, P2P, ONVIF, HD, 1MP, IR) is one of the popular options for organizing such a complex. The model is compact, mobile, easy to mount without cables. The viewing angle of 26°-90° and the optical resolution of the lens allow you to get a high-quality image of a large area. The price is 11950 rubles. also reflects the flexibility of the equipment, that is, the ability to integrate with other similar systems.

The word zoom migrated to the Russian language from the English zoom, which means "Increase". With it, you can visually zoom in or out visible objects. Image magnification can be achieved in two ways: hardware (using lens optics) or software (using applications).

Digital zoom (Zoom).

He's software. The increase is achieved by "stretching" the image.In relation to CCTV cameras, such a zoom is mainly used on PTZ cameras, the operator saw something interesting, pointed the lens at the object, if there is an optical zoom, first used it, in the case when the image is not large enough, digital zoom is applied. You need to understand that if the resolution is not large enough, and the object is far away, then we will get an overly stretched, poorly distinguishable image consisting of large pixels (dots). Another thing is if you have modern digital video surveillance cameras with a huge, in this case, the image using digital zoom will consist of more points, therefore the quality of the resulting image will be an order of magnitude higher. Digital zoom can be used on a DVR, on a digital IP camera, when viewing video on a computer using a player or editing program. It is a good addition to optical zoom or its complete absence.

Optical zoom (Zoom).
Magnification occurs by changing the focal length of the lens. Surveillance cameras with such a lens are called varifocal. Varifocal cameras with a 2.8-12mm lens are widely used. As you already understood, this is the range of focal lengths that can be changed, and thereby increase or remove the image.

The zoom lens can be equipped with an electric wire, that is, you can change the focal lengths remotely, using the settings on the DVR, computer or mobile application. A lens with this design is called a "motorized" lens. The cost of cameras with such a lens will be much higher. It is also worth noting the disadvantage of this design: in severe frosts, the operation of the mechanical elements of the auto drive may be disrupted, which can lead to the inoperability of the zoom in winter or before the onset of warming.

A zoom lens without an electric drive is devoid of such a disadvantage, the focal length and sharpness on cameras with such a lens are usually adjusted once - during installation. As a result, we get the zoom we need and the desired viewing angles, depending on the operating conditions.

Consider the features of the zoom (vario) lens 2.8-12mm.
2.8mm - in our case, this is the minimum extreme position, the picture will be as far away as possible, the image will be small, but the viewing angles will increase.
12mm - the maximum extreme position, the picture will be "zoomed", that is, maximized, while naturally the viewing angles will be minimal.
You can find a compromise, set the middle position, for example 7.4 mm. Everything depends on your needs.
If we compare the images obtained when using digital and optical zoom, then the optical one undoubtedly wins, because with a good matrix and optics it does not give visible optical distortions.

Zoom security cameras (Zoom).
These are surveillance cameras with a "motorized" lens, which we mentioned earlier. Most often, these are rotary street cameras, with the ability to adjust the zoom, focus and aperture. Most models are equipped with the ability to use digital zoom in addition to optical zoom.
Please note that such a camera has autofocus, otherwise, after each pointing at a new object, you will have to manually adjust the focus, which is not very convenient.

Rotary IP cameras provide a panoramic view of the controlled space. Any security system requires high-quality video surveillance. Accordingly, the ability to control the position of the surveillance camera in the vertical and horizontal plane opens up extensive possibilities for monitoring what is happening in the territory taken under control. "SpecTechConsulting" presents PTZ surveillance cameras with different turning speeds, image magnification and processing capabilities, as well as other characteristics, which together determine that the equipment belongs to different price categories. In addition, we immediately offer you a whole range of video surveillance services. Price for installation of video surveillance on a separate page.

PTZ IP cameras are preferable to purchase if you are interested in organizing the highest quality video surveillance. The presence of such a camera on a controlled object allows you to consider the smallest details of what is happening, thanks to the presence of the zoom function in them. PTZ cameras are equipped with optical and digital zoom. When choosing PTZ cameras for the implementation of a video surveillance system, it is necessary to pay attention to the most significant lens parameter - the optical zoom ratio.

Optical zoom uses the movement of lenses inside the lens to enlarge the image. This method of magnification does not affect the quality of the resulting video image. Digital zoom when enlarging the picture, unfortunately, leads to a loss of its quality. PTZ IP cameras presented in the "SpecTechConsulting" catalog have various characteristics, information about which is presented in full. Our experts are ready to provide professional advice and comprehensive assistance so that you can choose the best PTZ surveillance cameras for the implementation of the security system.

In "SpecTechConsulting" you can buy PTZ IP cameras for video surveillance outdoors and indoors. A distinctive feature of outdoor modifications of rotary ip cameras is their ability to work efficiently and continuously in a wide temperature range. Such rotary IP surveillance cameras are equipped with a special case, due to which weather conditions in no way affect the image received from the camera. Cameras intended for the implementation of video surveillance in closed spaces are not equipped by manufacturers with such protection against adverse climatic manifestations.

Every year there is an improvement of PTZ IP cameras, manufacturers produce new modifications with wide functionality and capabilities. SpecTechConsulting presents cameras from the best manufacturers, with the help of which it is possible to implement video surveillance in closed and open spaces at the highest level. Use modern electronics capabilities when implementing passive safety measures.

For outdoor video surveillance, Spetstechconsulting recommends using outdoor ip cameras that are perfectly protected from any climatic influences.
