Actual - How IP-based Video Surveillance Works -- Way Beyond Analog
When you’re shopping around for an IP-based video surveillance system, you will need to be particularly cautious about what exactly you’re looking at and what the individual terms mean. How IP-based video surveillance works is open to interpretation as far as some video surveillance and security salespeople are concerned -- not because they are trying to confuse the issues, but because there is no
According to USFDA, a combination product is one composed of any combination of a drug and device; biological product and device; drug and biological product
genuine consensus on what the term “IP-based” or related ones such as “networked” or “web-based” means.
Originally video surveillance was done based on analog technology -- closed circuit television (CCTV) and recording on video tapes. This was fine for recording what was going on, but it didn’t broadcast actual live information, so it wasn’t practical for monitoring stores, for instance, fr
