When most people talk about high-quality video, the conversation likely starts with — and quite possibly ends with — resolution. However, that’s only part of the story. There are many factors that go into a video camera’s ability to deliver the high-quality images necessary for today’s surveillance applications.
That’s not to say resolution isn’t important. In fact, says Tim Shen, director of marketing for Dahua Technology, based in Hangzhou, China, resolution should be high on the list of considerations. “I would recommend that dealers and integrators first consider camera resolution and determine how many megapixels are required for the system,” Shen says.
