The analog cameras have the advantage that their price has now fallen sharply. But it also means cables to shoot, an analog recorder to keep track of videos, not to mention finally the difficulty to access its cameras from outside. It is possible, but it requires additional hardware and skills, which makes this type of video surveillance system Nest vs Arlo more complex to set up, for something that is not really up to date anymore. I would rather advise IP cameras, which are now the standard, and whose price has also dropped sharply since we find today around 50 € to 100 €: In IP, it is possible to connect the cameras in Wi-Fi or Ethernet (network cable). The first is tempting for its ease of installation, but whatever happens, a power supply is necessary, except in very rare cases, like the cameras. Then, keep in mind that WiFi is nothing more than a radio signal, which can be scrambled with the right tools. We now find jammers at € 30 in Chinese shops … The best option is therefore wired IP cameras. Also, some are called ” POE “, that is to say, that they can be powered also by the network cable, provided to use a network switch compatible POE. In this case, there is only one network cable to pull, which is quite practical. As a safety measure, this switch must be connected to an inverter, just like the Internet box and the home automation box (if you have). Thus, even in the event of a power failure, the video surveillance system remains operational because it is powered by the inverter for some more time. Regarding IP cameras, it is possible to view them on your computer, via a web page, or on your mobile phone, thanks to an application provided by the manufacturer or not, since there are many compatible with various brands cameras:
Other concepts to consider
Many other notions can be taken into account when choosing a camera (such as the type of video compression, supported protocols, etc.). Some are sometimes very technical, and the purpose here is not to scare you. We saw the main ones just above, which is not bad. I will just add:
The design/size of the camera Nest vs Arlo. Some will opt for a discreet camera, which goes unnoticed, to film intruders without their knowledge. Others will prefer very visible cameras, which is in itself already a deterrent. Both arguments are equal.
The presence detection: most cameras detect movement by the difference between the two images. A simple cloud that obscures the sky can then be considered a movement, all the scenery darkening then. This technique is quite unreliable. Models incorporate a real motion sensor in addition to the lens of the camera, which is significantly better. Finally, more sophisticated models go so far as to identify precisely a shape or even a face, The respect for private life, especially for cameras filming your interior. There are few models to offer, but some manufacturers are starting to implement some practices,
