How to choose a security camera

Selection by technology

Today we can talk about two main technologies of camera systems - Analog and IP. Both of these technologies have recently become equal in terms of resolution and basic features. However, the fundamental difference is the method of transmission of the image signal. In analogue technologies (AHD, TVI, CVI), the image is transmitted via analogue coaxial cables. With IP technology, the transmission is fully digital and takes place via a computer LAN. Analog technology is advantageous mainly due to its favourable purchase price at the same resolution as IP and is suitable for smaller types of installations (family houses, small shops, etc.) or is a great replacement for old analogue camera systems with low resolution, while it can use the original wiring. IP camera systems are recommended for more complex installations where the wiring infrastructure is complex, or where the current data wiring in the building can be used (halls, factories, large stores and warehouses, etc.).

Selection based on infrared range (for night vision)

The main criterion for selecting a security camera according to the range parameter is the distance in meters. This value can be found for each security camera in the "parameters" tab. If, for example, the range is 20m, the model has such a number of LEDs or such a power that it can scan at night even in complete darkness up to a distance of 20m. It is important to know that every environment reflects light differently. A white wall will be seen at a greater distance than a dark coloured area or vegetation. For this reason, it is important to keep a necessary margin when choosing a security camera. In practice, this means that if you want to see reliably at 30m with your camera, it is advisable to choose a model with a range of at least 40m and preferably 50m.

Choosing by resolution

The resolution of security cameras is given in pixels - or megapixels (Mpx). The higher the value, the higher the image quality. Image quality is a crucial parameter of a security camera and therefore we recommend not to underestimate it. Currently in our offer you can find security cameras with resolutions ranging from 2.0Mpx (also known as 1080p, FULL HD with 1920x1080px resolution) to 8.0Mpx cameras (also known as 4K, ULTRA HD with 3840x2160px resolution).

Choosing a security camera by design

The main criteria for the right choice of camera type are operational features and design. In our offer you can find representatives of all major categories of security cameras.

.

Camera type	BULLET (roller)	DOME (hemisphere)	PTZ DOME
Description	Camera type used mainly for outdoor applications. All cameras are IP66 and above, so they can be exposed to normal weather conditions all year round.	Hemispherical shaped camera with antivndal chassis designed for indoor and outdoor applications. All cameras are IP66 and above, allowing them to be exposed to normal weather conditions all year round.	Motorized zoom cameras. Can be controlled via custom menu, DVR, or control panel.
When to choose	We mainly use for outdoor installations. Thanks to the canopy, the camera is perfectly protected against sunlight and other weather conditions. Installation is possible on any inclined surface.	Choose when the camera location is dangerously low and could be easily damaged. The antivandal aluminum alloy chassis and solid base make accidental manipulation of the camera very difficult.	This type of camera is quite expensive, so there must be a real reason for its use. We recommend using it where security guards will take advantage of the camera's mobility and operate it.
Where the camera can be mounted	interior and exterior walls, ceilings, soffits, columns (requires special mount)	interior and exterior walls, ceilings, soffits, columns (requires special mount)	interior and exterior walls, ceilings, soffits, columns (requires special bracket)
