IP cameras or network cameras are digital video cameras that transfer data across an Ethernet link. They are used most commonly for IP surveillance. IP surveillance is a digital and networked version of CCTV (Closed Circuit Television).
Advantages of IP camera
How to choose an IP camera
The first thing to consider is where the camera is to be installed. For outdoor installation, always choose weatherproof, waterproof and vandal proof cameras. But if you need an indoor camera, these factors are not that important.
With a PTZ function, you can avoid dead areas. These cameras have pan, tilt and zoom features which covers around 350 degrees in pan and 90 degrees in tilt. But if you only need the camera to be used for monitoring, fixed lens IP camera will be more than enough.
Decide how important the quality of the image is to you. A VGA camera with JPEG compression will have a lesser resolution than a Megapixel IP camera with H.264 compression.
You will not need wired IP cameras in cases where the camera is placed far from the router or hubs or if the signal is not strong. With the wired IP camera, you will have to make sure that you install it close to a power outlet or you may have to consider PoE IP camera, DC power pigtail or PoE splitter cable
