First of all, let’s remember what video surveillance is. We call “video surveillance” a network of cameras placed in or outside the home to be secured and which are most often connected to a recorder in the home or to an external or online monitor enabling the images filmed to be viewed remotely and thus monitor entry or exit points as well as valuables. You can go for the cctv systems london there now.
The Best Consultation
The consultation of these images remotely generally goes through an internet gateway connected to your personal box or to a 4G key allowing you to connect live or delayed to the videos live or recorded by the security camera. There are, however, different types of video surveillance installations such as dummy installations, installations with mobile or local vision with, for each type of installation advantages but of course also disadvantages. You must therefore assess what type of installation you need according to your desires and your accommodation. Here are some explanations about these installations:
- First of all, artificial video surveillance installations are intended to dissuade people wishing to break into your home. It is of course, however, possible to couple these false cameras with a real surveillance system.
- Local vision video surveillance installations are designed with cameras that send back the images taken on a screen located in your home and possibly record these images on a storage device also located in your home.
Mobile vision video surveillance installations work with IP cameras, that is to say cameras connected to the Internet and which make it possible to view in real time and remotely the images filmed by means of a computer, a tablet or smartphone. These installations require a Wifi network or a 4G key linked to your camera.
Mixed installations with mobile and local vision are finally installations which combine a system for viewing and storing images at home and viewing and storing external or remote images.
- In addition to comparing the different types of video surveillance installations on the market, you must of course take into account the type of camera offered by each system. In general, and before choosing a video surveillance system, we recommend that you estimate your needs as precisely as possible by assessing in particular the number of cameras you need according to the areas to be monitored, the need to place cameras inside or outside your home or both, or the need to connect your cameras to the electrical network or the Internet if you opt for a wired system.

When you consult the technical files of the video surveillance systems on the market, you will be able to compare different elements, here is a short glossary that will help you understand them:
- The viewing angle corresponds to the field of what you will be able to film with the camera.
- The objective concerns the viewing angle of the camera. Generally speaking, a large objective will see further and a small objective will see wider but less far. The size indicated here is often between 2.5 and 100 mm.
