Both solutions can be valid, however IP technology generally has superior performance:
Many IP cameras have high resolution lenses (Megapixel) and in fact they are often Full HD and even 4K ;
IP cameras work with a high number of frames per second and this results in greater fluidity of the images forbel.
It is advisable to design the system and its construction at the table:
It is easier and more flexible installation as, for the connections, it is sufficient to install a small local network, wired or Wi-Fi. The biggest advantage is represented by the fact that the NVR recording device can be placed with maximum freedom at any point, even at a certain distance, as long as it is connected to the network and this determines a strong freedom of design, even if it is It is always advisable to place in a safe place away from the reach of thievesIntercom Installers in Chicago.
Video surveillance with PoE technology: installation with a single cable
The PoE (Power over Ethernet) technology allows you to install IP cameras even with a single cable , in fact, it allows you to power the cameras directly via an Ethernet cable, using some conductors inside the cable that are not used to transmit data. In certain situations, this technology is even more convenient than a Wi-Fi connection.
Video surveillance with analog technology
In Analog CCTV systems, all cables used for video transmissions must converge towards the center of the system, where the DVR will be placed. In fact, this solution greatly constrains the design possibilities of a video surveillance system because the DVR must necessarily be in a barycentric position with respect to the position of the various cameras.
