Network cameras or IP cameras (Camere de supraveghere), is a relatively new technology appeared on the market. To function, this type of camera is connected directly to the network and send the video information either to a recording device (DVR) connected to the network or connected to a server. According to consulting firms in the field, were only 5 years, IP cameras (supraveghere video) will be preferred over analog cameras. And because the IP camera market is in full growth. Industry experts say the rule analog cameras still is felt primarily due to costs needed an upgrade, and secondly because of lack of knowledge of networking security departments. By analyzing the available options on the market, you can opt for a system of video surveillance full or partial IP IP. In other words, you can keep your investment in analog systems, but at the same time, you can enjoy the benefits of IP technology, the signal converters (from analog to digital). Functional safety systems with IP surveillance cameras (sisteme supraveghere) Although possible, a partial installation like IP, is not as practical as a full-IP, because the latter is 100% digital, contains very few mechanical parts and is very safe and more effective . IP surveillance cameras - low maintenance costs The asemeneea, maintenance costs of a system based on IP surveillance cameras are much smaller one compared to analog. However, in 2004 to one of American universities, has gone a combined solution, analog to digital simply because at that time, IP cameras were not as many features as today (such as interchangeable lenses , Automatic adjustment of white balance and light of the pound, etc.)..
