Wifi surveillance cameras for professionals

If the surveillance cameras market is currently booming, WiFi cameras have a lot to do with it. Very practical , relatively inexpensive , ensuring very good image quality and reliability , they benefit from all the advantages of digital cameras. It is therefore not a surprise that they now represent a very large proportion of surveillance camera sales for businesses as well as for individuals.

But this success leads to a real overabundance of models on the market, to the point that it becomes difficult to select the one that best meets your needs, especially for companies. However, in order to make the right choice , it is essential to know a minimum of information about these cameras and their characteristics. The potential user is then better equipped to study the different paradigmatic models of the market and compare their prices .

So how does WiFi video surveillance work and what are its advantages? More precisely, is installing a Wifi camera concretely as simple as announced? How to finally choose a WiFi camera for business, and at what price?

Operation and advantages of WiFi cameras

To understand the benefits of cameras using the WiFi network, it is important to know how they work – and how they should be actually installed.

Indeed, understanding how they work allows us to understand what they are not… and why they must escape the haphazard reputation of other wireless cameras.

How it works: why WiFi cameras are and… are not IP cameras

One of the main reasons that it is difficult to navigate the surveillance camera market is that resellers, and even hardware manufacturers, often use formulations that mislead the user .

Thus, many are those who oppose Wifi cameras and IP cameras . In their logic, the former are wireless cameras and the latter are wired cameras.

If they are to be believed, for the former, the data is transmitted over the Wifi network, generally to the user’s router or internet box, so that this user can scan the images on his computer or smartphone. And for the second, the data is transmitted by Ethernet cables. Other commentators or sellers, on the contrary, equate Wifi cameras and IP cameras , suggesting that all  are Wifi cameras!

However, the very name of “IP camera” is incorrect: in reality, the two types of cameras, wired by Ethernet or wireless by Wifi , are cameras “on” IP, which use the Internet protocol ( Internet Protocol or IP in English) to transmit their data . Simply, the internet protocol is used by a wireless transmission system for WiFi devices and by a wired transmission system for others.

To conclude, the confusion is all the greater since… all wireless cameras for businesses are not cameras using WiFi networks . Indeed, there are also analog wireless cameras using conventional radio waves , but these systems are disappearing. And to tell the truth, as explained below, it is not worse.

The installation of a WiFi camera in detail

The installation of a wireless surveillance camera of the Wifi type presents few difficulties.

Indeed, it can be positioned on any flat surface , even if it means adding a support to a pole.

And they can be positioned far from the receiver: the network range can reach 100 meters . In addition, this range can even be improved by adding a WiFi repeater or amplifier.

The main difficulty is to have the camera detected by the router to which it is connected , but the software inevitably supplied with the equipment generally turns this task into a formality .

However, the services of a professional network installer will undoubtedly be required when it comes to operating a complex installation with several different cameras of various models transmitting their data over Wi-Fi or not to a single video surveillance center.

Advantages: the strength of simplicity, the flexibility of digital

Wireless cameras have left behind a mixed reputation, not to curry favor with businesses. It is in this respect interesting to note that it is because the cameras operating on the WiFi network initially appealed to individuals, who had little exposure to traditional wireless cameras, that wireless is ” income ”in the business.

Indeed, cameras using WiFi networks have many advantages and do not suffer from the shortcomings of traditional wireless cameras:

– The most obvious advantage is that they do not require the laying of any cabling between the router and the camera. As explained above, the installation procedure is extremely simple;

– In addition, these cameras can be installed outdoors as well as indoors;

– They can even work at night , for models equipped with lighting or infrared devices;

– Installation is also all the simpler as the Wifi signals are less sensitive to obstacles or interference than the radio waves fitted to traditional wireless cameras;

– This explains why the quality of the images is often much better than that provided by analog wireless systems and which had given a bad reputation to wireless video surveillance;

– But the main advantage of the camera connected via WiFi is to combine the advantages of wireless with those of digital. Thus, it is possible for the user to view the images on his computer, tablet or smartphone , when he wishes and from where he wishes, as long as he is connected to the Internet. Images can be saved not only locally on a server or hard drive but also in the “cloud” . The fact that the videos are digital also allows a large storage capacity and above all, with the appropriate software, great flexibility in the use of images for detailed archiving, fine analysis and image processing.  

– Another intrinsic advantage of digital wireless video surveillance systems is their scalability  : they can easily adapt to the needs and changing needs without the need to make major changes to the network infrastructure,

– Finally, digital systems over IP, including WiFi systems, are now often less expensive than wired alternatives with coaxial cabling. Management costs are also lower, with the use of storage on standard servers, the absence of proprietary equipment, easier communication with the security teams who may be under contract, etc.


  1. I needed to create you one little observation just to say thank you as before for these gorgeous information you’ve discussed here. It has been certainly particularly generous of people like you to convey freely all that a lot of people could possibly have made available as an e book to earn some cash for their own end, especially considering the fact that you could possibly have done it if you ever decided.
