When installing a security camera system in commercial or even residential environments using digital TCP / IP and PPOE technologies it is very common to have doubts, because what seems simple often becomes quite complex and we can even wrap ourselves in the material that We will need to perform the services.
Therefore, we must not ignore the doubts but look for the answers so that we succeed in the installations of the IP technologies of cameras. The most common questions are:
- Will I need a dedicated network or link just for the security camera system?
- How many security cameras will I need to monitor this environment?
- Will I need to have how much internet speed for my network?
- How many days of recording do I have to have on my network?
- How big is the HD hard drive to store the images?
The answers to these questions are relatively simple …. First we have to structure a network only for IP cameras because depending on the amount and resolution, the traffic will be high thought and therefore, we do not recommend that the IP cameras are linked to the same network of work.
There are in the market IP camera manufacturers with a resolution of 1920×1080, these are already considered FULLHD and when their images reach a frame of 0 ~ 30 per second will easily cause a congestion in the work network
To better answer your questions, we’ve put together some key tips for building and structuring an efficient video and monitoring system for commercial or residential environments.
# 1 Network Infrastructure and Cabling Tip
Video traffic is one of the most sensitive to loss of communication, that is, there is no way to retransmit video data without affecting the quality of the final material, this also occurs with voice transmission.
Our tip and recommendation is that the network and data cabling infrastructure be assembled, structured with quality materials and not installed next to the electrical network infrastructure and electric motors as they may cause electromagnetic interference over the data network cabling.The installation of the infrastructure must comply with the standards for network systems, according to NBR14565.
# 2 Switch Tip
The Switch, the equipment that will link the cameras to the servers and monitoring stations, must have adequate data processing capacity for the flow that the camera network will generate.This concern with the data packet processing capability is due to the fact that data traffic from a camera network is constant and therefore the Switch must be prepared to process these packets.
# 3 IP Camera Tip
Not necessarily the most expensive camera is usually the best, in our point of view, we have to choose a camera that meets us and that has the resources we need.Today in the market we have many models and we do not have to always choose the most expensive, but the one that meets our project.
