The use of cameras for the protection of property, real estate and even people, is very common. There are different types of systems to do this effectively, the main one being called
CCTV video surveillance, Closed Circuit Television or Closed Circuit Television. With this method, the control, supervision and random analysis of the content obtained is achieved, from one or several monitors installed in a control room. The
video surveillance cameras they transmit a signal over an IP network to other computers on the network, be it a computer or a smartphone. The streaming protocols become the protagonists, allowing the transmission in real time and with the use of the web browser of your choice. The
IP videos They are obtained through wired or Wi-Fi networks, with higher quality and lower cost. This article will help you clear up any doubts that may arise on these issues. Above all, if you are looking for information to acquire one of these and improve security conditions with experts who offer you state-of-the-art equipment and applications.
What is CCTV Video Surveillance about?
The system
CCTV video surveillance It is made up of a series of teams that together are in charge of controlling and recording the activity in a given space. First, there are the cameras; which represent the beginning of the process, since through them the facts are captured. Most include a microphone, and in addition to that, they have a set of features that give them a specific use. For those who don't know, the
video surveillance cameras come without
lenses. Therefore, when you hire the installation service, you must indicate aspects such as the minimum angle of observation or the intensity of the light on the site. In this way, the image of the object to be protected will be the most suitable. Also included are
monitors or televisions, which are the receivers of the video. However, they are the
recorders located in the control position, which are in charge of making copies of what is captured. In the past, these duplicates were archived on tape, but with advances in security technology, they are now being stored on computers with large memory sizes. Another option is to use servers or hard drives; everything will depend on the amount of material generated. While the device that allows viewing several images in real time, projected on a single screen, is the
video matrix. You can also route the output to multiple monitors, the sequence of appearance, etc. Regarding the
lines of transmission, video signals can reach up to 8 MHZ frequency, so coaxial or UTP cables are used.
Advantages of an IP video surveillance system
Accessibility
The
IP videos represent a series of advantages for the application of
CCTV, which are not offered by traditional closed-loop systems. The first one is the possibility of having remote access to the cameras and servers. Therefore, as long as you have authorization, there will be no limitation of time or place to know what happens in the guarded area. So since you are done, you can do without the physical control room.
Economy
On the other hand, saving in economic matters is one of the greatest benefits of the
IP technology, Well, when using the internet, many times organizations already have it, so no installation is needed. It should be noted that the expense is much lower when opting for the wireless alternative and cloud storage. In this way, the investment is mainly in the
network cameras. There are many other qualities of
IP videos on
CCTV, like the quality of the image since those of network offer a better resolution. In addition, because they do not undergo format changes when storing or retrieving, they do not lose sharpness. At the same time, intelligent software can be implemented to help you filter events or detect irregular situations, without having to be in front of the monitor. In many cases, they send notifications or trigger alarms.
Most common applications of CCTV video surveillance
Within the field of security, IP videos have many applications. For example, in traffic, where they are applied for license plate recognition, vehicle traffic control or public transport units. In industries, surveillance cameras inspect production processes or chains. More recently, security agencies analyze people's faces to detect suspects in public spaces; such as airports, squares, service stations, among others. Even in the domestic, educational or work context, video surveillance is useful for controlling interpersonal relationships. As you will see, the use of cameras for surveillance is very common. So if you want to acquire one of these systems, evaluate the conditions of the area and your needs well. In addition, hire specialists to advise you on the equipment that is best for you.
