What factors should you analyze to design the best closed-circuit TV? We will tell you about them below.
Cameras
There is a very wide portfolio of cameras. It is not that one is better than the other, but that in each case their characteristics and applications have advantages and disadvantages. Your goal in selecting the right one should be to be clear about what you need. For example, what are the areas you want to monitor?
The appropriate alternative changes if your objective is to monitor the perimeters of your company, neighborhood or home to avoid intrusions or if you try to control a production process . Also, the camera to choose will be different depending on the climatic conditions of the place where you are going to install them and the available lighting. These factors may make it necessary to purchase a night vision camera or determine the minimum color and resolution to obtain sharp images.
If the dimensions of the place are extensive, you should choose lenses that allow you to have optimal ranges of vision and other technologies will be useful, such as motion detection and incident notification, which allows recordings to be activated when a need is detected, avoiding recording constant use of unusable images and saving space.
Another aspect that you have to evaluate is the management system and the resources you have. Both the monitoring and recording systems present suitable alternatives for the affected personnel and characteristics of the sector.
For example, modern systems allow cameras to be controlled remotely from centers of operation and monitoring, configuring remote zoom, pan, and tilt, among other functions. In addition, you can choose to have the monitors observed in real-time or accessed remotely using the internet and electronic devices, whenever you want or if you receive an incident alert.
Likewise, there are devices that allow the recording of a time sequence, capturing continuous images, while others allow the time interval to be filmed to be defined, obtaining partial recordings.
Recording and storage equipment
If before the occurrence of an event you need to analyze the recorded images, the quality and easy availability of the recordings is essential. In this sense, the most modern closed circuits of TV use Digital Video Recorder systems, known by its abbreviation “DVR”, which have many advantages over traditional tape recording devices (VCR). The main difference is in durability and ease of tracking as well as the image location.
These teams have multiple functionalities that allow, on the one hand, to store the video sequences on hard drives and, on the other, to manage and manipulate them as needed, thanks to modern software.
In these systems, multiple cameras can share the same monitor and storage hardware. There are teams that support from 6 to 64 cameras, with the possibility that each one records at a different speed, depending on the importance of the scenes. Technology also allows you to choose which camera you want to view on a monitor and alternate them as desired. However, the most modern equipment uses multiplexers, which are devices that allow images captured by different cameras to be viewed on the same screen.
A good IP server with a large storage capacity is also vital for accessing live and recorded images. On these devices, the images are often compressed to save space while making it possible to retrieve the videos to an acceptable quality.
