The demand for IP cameras has increased considerably. These cameras offer unparalleled image quality versus the traditional analogue cameras. Since many building were built years ago, no one planned for the installation of Cat5 cables in order to transmit from elevators. It is very expensive to have these cable installed by elevator providers. Several developers are now using antennas. They are just as reliable as cables but offer a much cheaper alternative with a transmission of 150Mbps. It is thus possible to install any camera model, even 360-degree cameras for unequalled surveillance.
