Megapixel IP cameras are becoming much more popular in surveillance applications, and many manufacturers have introduced new megapixel cameras. These megapixel cameras are being offered at prices that are not much more than the older VGA cameras. This camera review compares the latest megapixel dome IP Cameras from Axis, IQinvision and Ganz (division of CBC). Cameras range in price from about $659 to over $1100. One thing we always say, you get what you pay for, so understand that there are product performance and reliability differences. Take a look at our previous article; High Resolution Megapixel Cameras are Not all the Same which describes the differences in cameras. Axis was one of the first companies to introduce IP Cameras and has recently moved into the megapixel market. IQinvision was one of the first companies to introduce megapixel cameras and have the most experience in this technology. The new megapixel cameras from CBC, Ganz are the latest entries from a company that is well known for their high performance lenses. We compared the Axis P3344VE-12mm version, IQinvision IQM31NE and the new PixelIPro ZN-DT1MA from Ganz. The review compares some key specifications, and provides a comparison of the video quality based on the tests we did.
All the cameras have vandal resistant outdoor housing with IP-66 rating. They are all day/night type cameras and can be used indoors or outdoors, provide about the same resolution, are powered using PoE and have 2-way audio capability. They have frame rates up to 30 fps, support H.264 as well as MJPEG compression, and have input and output I/O connections. Even though these cameras appear to be alike, they have distinct features and pricing that makes each one suitable for specific applications. Be careful when selecting a camera that has two-way audio or even alarm input and output connections. The camera may have the function but the IP NVR (or VMS) software may not support these functions.
