IP equipment from RVi.
IP equipment from RVi In recent years, the security television market has seen a significant growth in IP video surveillance systems. These systems have a number of significant advantages over traditional CCTV systems, such as: the ability to transmit high-resolution video, use of the existing network infrastructure at the site, significant reduction in cables during project installation, etc. And due to the growing demand for inexpensive, but high-quality equipment for IP video surveillance systems, IP cameras and IP video servers under the RVi brand, well-known in the CCTV market, have gone on sale.
The RVi-IP line is based on standard IP video surveillance cameras. Such IP cameras are the most widespread, as they are capable of solving a wide range of tasks: from surveillance in supermarket sales areas to outdoor surveillance (when installing the camera in a thermal casing).
If the task is to install an IP video surveillance system that can operate in low light conditions, then an IP camera can be used to solve this problem RVi-IPC20DN. This camera transmits an image of 704*576 size at a video flow rate of 25 fps. Due to the use of a mechanical IR filter and a highly sensitive Sony CCD matrix in the camera, this network camera has high sensitivity — up to 0.008 lux.
Since the RVi-IPC20DN is not a megapixel camera, you can select an inexpensive lens with the focal length required for the task at hand.
If the task of obtaining a clearer, more detailed image is important, then for this it is necessary to use megapixel cameras RVi-IPC21 and RVi-IPC21DN. It is important to note that due to the use of CCD matrices, these cameras have better light sensitivity compared to megapixel network cameras on CMOS matrices.
RVi-IPC21 is a megapixel IP camera with electronic switching «day-night», which allows it to be used only in good lighting conditions.
RVi-IPC21DNalready equipped with a mechanical IR filter. Thus, this camera, like the RVi-IPC21, provides high resolution of the transmitted image and has a sufficiently high light sensitivity for megapixel cameras (up to 0.02 lux).
Another advantage of RVi IP cameras, which is appreciated by installers of IP video surveillance systems, is the function of transmitting power over a network cable (PoE). Also, a single network cable transmits sound from a built-in or external microphone and information about alarms (about the triggering of a motion detector or any external alarm). All this significantly reduces the costs of installing and starting a video surveillance system.
RVi IP video surveillance equipment is capable of solving a wide range of security television tasks — from surveillance in difficult lighting conditions to transmitting high-resolution video. RVi IP cameras are the middle ground that customers often look for — inexpensive, functional and reliable equipment.
