Some things to consider in choosing a suitable video surveillance system

To choose the most appropriate system, different criteria must be taken into account to find the optimal solution according to the needs. The ten points of the following comparison between analog and digital systems can be helpful when making a decision.

1. Planned application

If the video surveillance system has to provide details in high resolution, megapixel IP systems are the right choice. A megapixel network camera with 6 megapixels, for example, collects 60 times more details. The high resolution analog cameras are able to collect more details but have problems when playing the moving images.

2. Existing structures

Since IP networks are already installed in many companies, the installation of IP security systems is usually relatively easy and affordable. The installation of IP camera systems generates much lower costs than analog transmission since the necessary infrastructure is already available. In analog cameras, a problem and a factor that produces costs is the additional installation of the power supply. Regarding the networks and based on our experiences, Bosh CCTV Systems could be your consideration for their IP camera systems can reduce so many costs.

3. Frame

A decisive advantage of megapixel systems is that, thanks to their high resolution, they require fewer cameras than analog or normal IP systems to provide the necessary framings. Hemispheric lens technology allows you to obtain a panoramic view (wall installation) or a 360 degree view (ceiling installation), which allows you to monitor an enclosure with a single camera.

4. Data transfer / bandwidth 

If several IP cameras or high megapixel resolutions are used (in the case of many cameras), it is necessary to install a special video network to avoid problems with the bandwidth. When the volume of data is high, it is also recommended that the cameras have QoS (Quality of Service) to ensure the bandwidth required for the video flow and for the transmission of control commands through the network.

5.  Data storage

If the network cameras have internal memory it is possible to overcome failures in the network of several minutes, a brief maintenance of the components of the same or the change or restart of the recording computer without losing data.
