Video surveillance

We have developed an online estimation calculator. You can enter the number of outdoor and indoor cameras and how long you would like to save the videos in your archive.



Question mark
  • 4K Ultra HD security cameras possess a high resolution of 3840*2160 with over 8 million pixels. And they are also called 8MP/2160p security cameras. Though 4K IP cameras are not budget-accessible and prevailing now, they can greatly enhance your video streaming experience with no doubt.
  • 1080p Full HD security cameras produce images with the resolution of 1920*1080. They are suitable for the general-purpose video surveillance but sometimes may fail to figure out small details from a distance.
  • 720p HD security cameras shoot images with 128*720 pixels per unit. Due to the growing demand for higher quality images and videos, 720p security IP cameras are now gradually losing their grip in the market.

Question mark
Depending on what difficulties our specialists will have to face, a final estimate will be drawn up. For example, if cameras need to be mounted at a height of more than 2.7 metres, this is already considered high-altitude work and, in accordance with safety precautions, two engineers are required for its implementation.

Thinking about video surveillance, the first question that arises is which camera to choose. Why do we need remote cylinders on the brackets – where are spherical ones better suited, in which case you can get by with a budget mini-camera; we figure it out together.

Analogue or IP Camera?

There are two classes of surveillance cameras: analogue and digital (IP). Here we briefly note the basic differences between the two types.
Analogue CCTV cameras have recently lost their position in the modern market, but still have the benefit of affordable prices. They do, however, require more cables (from 2 to 3) and additional connectors. Analogue cameras are poor in functionality, which cannot be said about the digital class.

IP cameras offer many more features. Modern IP cameras have extensive functionality: speakers, microphones, integrated analytics, various detectors, and support for cloud technologies. Installation is also simpler – for a video signal and power supply, one cable is enough thanks to PoE technology.

For Small Rooms

Modest areas, such as at the reception in a small office or above the store counter, usually need targeted tracking. Miniature cameras are great here. Here’s what you might find useful when choosing a camera:
  • Focal length. If the coverage area is large enough, choose models with the parameter F = 2.8–3.6 mm – such cameras have a larger viewing angle. With a focal length F > 4 mm, the viewing angle decreases sharply, and in a small room the camera will not have enough coverage.
  • Wi-Fi eliminates the need for an additional cable.
  • Two-way audio communication implies a built-in microphone and speaker.
  • Slot for memory cards – the camera can be used without connecting to a DVR
  • IR illumination is useful for night shooting or in a dark room.

For Office and Home

Where you need an overview of the space in all directions, domed or spherical cameras are more suitable. They easily fit into any interior, while not attracting too much attention, and they are convenient to install and operate. Installation is very convenient – the position of the lens is easily adjusted after installing the camera.
Given the specifics of the objective , you must choose between simple and anti-vandal cameras. In addition to the case design, you should pay attention to the presence of a microphone, IR illumination, a Wi-Fi module, and an installed lens. The suitable lens value will depend on the location of the camera.

For Streets

The nature of external CCTV makes clear the requirements for these cameras. For tracking the perimeter of the building, the adjacent territory, and other objects, bullet or cylindrical camera models are more suitable. There is a special foot for installation, and a hinge paired with adjusting screws changes the position of the camera in the plane. The housing often houses a small elongated visor to protect the lens from exposure.
Outdoor installation involves the selection of cameras with a degree of protection of at least IP 65. This parameter indicates the class of sealing of the device. The first digit indicates protection against dust, and the second is protection against moisture. Since in this case the cameras are installed outdoors, the optimal degree of protection will be exactly 65, where 6 is full protection against dust, and 5 is protection against water jets from all directions.

The range of IR illumination is also important – it is used in the dark to support visibility.

For Large Areas

For shopping centres and specialised sites, the use of PTZ cameras is optimal. They are distinguished by high mobility and the ability to control them remotely – at a distance, you can rotate the camera in different axes, change the position of the lens, and zoom in and out.
In situations where it is difficult to use multiple cameras, it is better to use cameras with a Fisheye lens. Their case is somewhat similar to dome cameras – these models, however, are smaller in size and flatter. Because of the installation method, they are convenient for both the wall and the ceiling. It is noteworthy that the viewing angle reaches 180 degrees on each axis.

There is another kind of camera: modular. In this case, the camera comes without a lens and is made in a standard rectangular case; the lens is selected independently. This solution is popular for shopping centres and large facilities.
