If you have young children and you want to know what they do at home when you are away, whether there is a nanny with them, whether you have elderly parents who need care and you want to be sure that they are all right, whether you are cleaning up home when you are not on site and you want to control that everything was done well and nothing was stolen, I recommend you install CCTV cameras which are both wired and wired and can be installed in any place even after repair, so as not to drill the walls . The set for home 4 wireless cameras with installation without any monthly payments will start from $ 500, installation will take about 2-3 hours. I also recommend installing outdoor CCTV cameras to protect and scare away potential robbers and thieves. A set of 4 wired cameras with installation at no extra monthly charge will start at $ 1,300. It includes cameras, cable, all materials and work. If you are interested in the safety of your family, I recommend that you install a video surveillance system and be protected and calm for your loved ones.
