Indeed, the options of cameras present on the market today are numerous, and it is better to opt for the one which will be able to meet your most important needs. If you have a precise idea of your questions, do not hesitate to go directly to the relevant section.
Do we need a wireless or wired connection?
Rest assured, both exist. If your camera is located close enough to your modem / router or your Wi-Fi network is not the most powerful, you can opt for the wired connection. This will be done via a standard Ethernet cable, mostly supplied with the camera. Connection is very simple: just place the cable in the Ethernet port on your camera and connect it to an available Ethernet port on the back of your modem or router. For a wireless connection, the installation depends on the camera software. The positive points of this connection are that you can avoid tedious wiring and that the range of a Wi-Fi signal can reach 100 meters: ideal indoors and outdoors.
What image quality do we need?
Image quality depends on three different factors:
The sensor: there are two types of sensor on the market, CCD and CMOS. CCD sensors mainly equip compact cameras while SLR cameras mainly use CMOS sensors. While CCD sensors have always offered better image quality than CMOS, CMOS has made a lot of progress in recent years and its much cheaper to produce
The definition: for a very long time the definition of the image of a camera was limited to VGA (640 x 480) but we find more and more cameras offering HD definition (1280 x 720) or even Full HD (1920 x 1080).
Lighting: this is expressed in Lux and determines the brightness necessary to obtain a good quality image.
