An IP camera, also called a network camera, is a camera with an IP network connection. It can also be described as a camera and computer combined into one unit. Captured video is transported over an IP network via network switches and is recorded to a PC server with video management software.
That sounds simple enough but when you’re trying to choose the right IP camera you’ll begin to notice how many different types of cameras there are: fixed, day/night, wireless, indoor, outdoor and PZT, etc. Just follow the guidelines below, and you will get the IP camera to fit your specific requirements.
Function is not the more the better. Network camera own many functions, but it does not mean products with more functions are more suitable for us. The reason is very simple. The more functions means its price is also higher, but some features are not necessarily everyone can use. Since the network surveillance camera transmission mainly relies on the network, if the camera resolution is too high, the data will be increasing which lead the trouble of network real-time transmission. From the current network situation, 640 x 480 resolution is the basic image real-time transmission limit. In addition, there are still some details calling for attentions when we purchase. First of all, check the surveillance camera volume - in general, the smaller the better, because the smaller ones are not easy to attract attention. Secondly, find whether the accessories are full range. Finally, the priority of wireless products is necessary. The biggest advantage is to reduce the trouble of wiring, and for more casual placement. Of course, the premise is to own a wireless router at home, and to ensure that the surveillance camera position has sufficient signal transmitting image data.
