Business Security Information

IP Cameras are surveillance or CCTV cameras that use IP (Internet Protocol) to transmit a video image and any control signals for the camera over an Ethernet network.  IP cameras are also referred to as network cameras.  They are usually recorded using a digital video recorder (DVR) or a network video recorder (NVR).  The use of IP cameras allow the video to be stored and retrieved from anywhere on the existing network.  IP cameras also allow a business to view the cameras through an internet connection or across private networks such as LANS (local area networks) or WANS (wide area networks).  Also, IP cameras are able to be deployed or used across a wireless network.  Resolution of IP cameras, just like digital cameras, has improved over time.

One of the advantages of IP cameras is a cost savings when you use existing networking equipment and cabling.  If additional cabling is needed, it is usually cheaper to install Cat 5e or 6 cable instead of coaxial cable.  Using existing infrastructure to install an IP security camera system is possible, but is not recommended for most installations because anything that affects the IT network will also affect the security camera system.  For security purposes, it is usually recommended that a dedicated network be set up or, at the very least, a separate sub-net should be set up and used for the IP camera system.  Another advantage of the IP-based surveillance system is that it can be powered using POE (power over Ethernet) which allows one cable to handle the power to the IP camera as well as transmit the video data.  Thirdly, IP cameras have the ability to be customized in many ways, including additional support for a variety of image resolutions, ability to select frame rates and resolution for each camera, and the ability to choose different video compression methods.

One current disadvantage of most IP camera systems is the higher cost of IP cameras over regular security cameras.  The cost is coming down with time and eventually should not be a factor.  Also, the use of IP cameras require that your network have high bandwidth capabilities.

IP surveillance camera systems are usually considered more scalable then regular surveillance systems and can grow and change to meet your surveillance camera needs.  The use of IP cameras may not be suitable for all businesses under all circumstances, but before investing in a new security camera system or upgrading an existing system, a business should look at the long term benefits of IP surveillance camera systems.
