The most important and basic element is the network cable, some cameras rely on this, others rely on a wireless connection, and some also provide a choice between wired and wireless connections. However, the wireless connection is less stable and high-quality, since the image quality decreases when viewed remotely.
Power cable
As for the second element necessary to connect the camera is the power cable: this cable is the one that determines the position of the camera monitoring diameter, as it must be close to the power source, otherwise the distance of the power source from the camera location will force you to buy more extension cords. On the other hand, many types of surveillance cameras depend on the battery, and in this case you can put them anywhere without restrictions, but they should be checked and periodically checked every few days.
Night vision
Night vision-the second consideration is what the camera sees, and there are two considerations: the first is night vision using infrared light, as cameras can take picturesin the dark enough. The second is the viewfinder - some surveillance cameras come with a lens called a fisheye, which provides a field of view that can cover an entire room when you stand in one corner. Not all surveillance cameras have such lenses, but some of them can cover the range itself with electric hinges that allow the camera to be rotated to scan the entire area.
Microphone and speaker
Many cameras include a motion sensor whose primary purpose is to send you alerts about suspicious movements at home. But it can also be used to turn on the lights when you come home or wake up at night, and turn them off when you go back to sleep.
