For more information on why it is so important to use an Active PoE Switch or Active PoE Injector, refer to our guide on understanding the Difference Between Active vs. Passive PoE equipment will damage any IP camera and void its warranty. PoE switches and injectors meant for wireless access points are Passive in their power delivery, meaning they do not negotiate the correct power required for the camera. It is very important to use PoE equipment that is compliant with 802.3af or 802.3at standards, which ensures correct power delivery to the cameras. IP cameras can be powered near the installation point with 12V DC adaptors, or can utilize PoE technology in the PoE switch that provides power and data from one convenient device and over one cable. Powering and transmitting data from IP cameras requires networking equipment to do so. PoE Switch that is 802.3af/at CompliantĪt the heart of the whole network that pumps data between cameras and recorder is the PoE switch. The following 5 components comprise an IP based camera system that is setup over a network. What is needed to setup an IP camera system over the network? For easy to setup wireless systems, we recommend these plug and play wireless camera systems. It requires prior knowledge or a skilled IT technician to properly deploy a WiFi camera system over the network. Deploying wireless cameras over a network is much more complicated and beyond the scope of this guide.
These types of installations are still common for home users or businesses who purchase and have the following situations:
In this time people had to know how to connect and configure IP cameras to work over a network for the recorder to store surveillance footage. Prior to 2012, there was no such thing as a PoE NVR that came with built-in Power over Ethernet (PoE) Ports. There are many reasons to understand how to setup an IP camera system over a network. Who should setup an IP Camera system over a network? Internet is only needed if you would like to have remote viewing capabilities to watch your IP surveillance system over the internet when you are away. A computer network required by an IP system is called a Local Area Network (LAN), which is basically a PoE switch connected to the cameras and the NVR.
No, you do not need internet for an IP camera system.
The IP camera sends video and other data in digital format over a network cable to the NVR. IP camera systems comprise of one or more IP cameras that are connected over a computer network to a Network Video Recorder (NVR) or Digital Video Recorder (DVR).
