And it is for this reason that, in principle, many specialists in the sector advise to bet not on one, but on a kit of closed-circuit video cameras dedicated to surveillance.

In this perspective, we could say that one of the solutions that may seem more appropriate, in terms of quality and characteristics, is the one that refers to

CCTV cameras that are part of a video surveillance kit with at least a series of key and key features, such as 1080p resolution, night vision, of course, the alarm and also some others such as the so-called motion detection, the possibility of being waterproof with a security system guaranteed to IP66 and, again, a wi-fi system, that is, both wireless.

We must say immediately, it is certainly not a system that we can buy with a few pennies, but not even a huge outlay, especially if we are going to commensurate it with the high and marked shooting quality and a whole series of reference features. 

Ease of installation and use, these kits increasingly benefit from the plug and play system. In a nutshell, after connecting them to the power supply, just connect the NVR directly to the monitor and router and select the camera. Consequently, like all plug and play systems, the CCTV video will be displayed on the screen in seconds without having to do anything else.

Basically, no cables are needed between cameras and NVR. Among other things, if these external closed-circuit video surveillance kits support the wi-fi system it is even better: remember, however, that we are talking about at least a series of 4 cameras.

Wi fi, Full HD, motion detection – Other Features

When choosing a CCTV camera, one of the main indications to keep in mind is to get into the merits of some of the most popular features such as Wi fi, Full HD resolution, and motion detection. With them, as mentioned above, the reality regarding the waterproofing of the devices must be analyzed.

The existence of a wireless system decidedly practical, intuitive and functional is one of the parameters to which we must give the right weight: having the chance to have CCTV cameras that guarantee a stable wifi connection is nothing short of vital and crucial for the purpose for which we think about this. kind of installation of video surveillance systems.

At the same time, pay attention to the signal reception distance: which normally, in the open area, is equal to 50 meters, or 10 meters if it passes through the wall.

As mentioned before, an IP66 waterproofing system is suggested.

At the same time, the main resolution that many suggest is that of full HD at 1080P with the possible integrations, now in fashion and trend, of a 2MP image sensor that serves to make the images sharper and more distinguishable.

At the same time, roads that lead to a system equipped with night vision are by far suggested so that the wifi external video surveillance kit can really protect and observe the home or office for the whole 24 hours.

To this is connected, as mentioned, the aforementioned motion detection system, which as a rule and as a rule nowadays is also customizable: in practice, the CCTV video surveillance kit must be equipped with a system aimed at dynamic monitoring of the entire protected area through sensors capable of identifying motion detection and doing it with customizable programs.

In practice, with every ‘suspicious’ movement, you receive reports, alarms, messages or indications on the app.


Home safety can be a real issue if you are not prepared for it. There are a lot of things that can go wrong, and having a good safety system in place can save you a whole lot of trouble.
