NETWORK IP CAMERAS
IP cameras allow installation flexiblitly and super high resolution recording.
IP cameras are the future of security systems, as they have have the greatest method of installation and highest available picture quality of all current camera systems. IP stands for 'internet protocol' and as the name suggests IP cameras use a new or existing network to communicate and can be linked using the internet. As a result you can install a camera anywhere there is the internet, which is basically anywhere.
Each IP camera is essentially a small computer with a camera all in the one unit. The advantage of an IP camera is you don't actually need a recorder to use the camera. The camera can be connected directly to the network. Once connected the video can be saved in many ways.
On to an SD card installed into the camera.
On to a server using software to control the cameras.
On to an 'NVR' network video recorder. A standalone recorder similar to a traditional CCTV DVR recorder.
A standalone camera with an SD card would be suited to a small area you simply want to remotely view, such as a workshop or home. If your security alarm goes off, you could check your camera in live view to see if there is an intrusion. Motion detected by the camera can even be emaied to you directly from the camera in a small video or image. The SD card saves a limited amount of video.
A Server using software is best suited to a business or somewhere where you always have a computer running to record the footage onto the hard drive, Software such as Geovision can control as many cameras as you need. Footage can be remotely viewed by logging into the server over the internet.
A standalone NVR is best suited to a small camera system for a smaller business or home with multiple cameras installed. All the cameras are connected to the NVR via the network and the NVR acts as a dedicated server so you dont need a computer constantly running to look after your cameras.
IP cameras are very versatile in installation as they dont need their own network or power cable to run all the way back to the recorder or server. You can have several cameras connected together using a 'Network PoE Switch'. Power and data is sent from the switch down the single cable to the camera. Also only a single cable is required from the switch to the router/server.

STANDARD OR MEGAPIXEL?
IP cameras come in many specifications of image quality.
Most standard IP cameras are 640x480 pixels (VGA), which is about the same clarity as a standard analog CCTV camera. You will see the term 'megapixel' mentioned alot when it comes to IP cameras. Megapixel is simply a term for any camera over 1000 pixels in width. Common resolutions are 1MP(720p), 2MP(1080p), 3MP and a huge 5MP. What size you need depends on the clarity you require. A standard 640x480 camera is enough to check on your property remotely. For security and footage, typically a 1MP or 2MP camera is more than enough detail and compares to the clarity of a blue-ray video. The higher you go in quality, The more expensive the camera and the more network bandwidth it uses.
IP CAMERAS AND NETWORK BANDWIDTH.
IP cameras have many advantages, but also disadvantages vs tradtional CCTV and HD-SDI CCTV. CCTV uses its own co-ax cables to connect to the DVR recorder, and each cable is designed to operate each camera individually. Since IP cameras run on your network, your network can become very slow as all the video data is being constantly sent to the server or NVR. This doesnt leave much bandwidth or room for your other devices on the network, such as computers. A few 1MP cameras is usually ok, but once you have too many or some 5MP cameras running, It can become too much. To overcome this you would need to install a seperate network in the property dedicated to the camera system.
Below is a diagram of how a typical configuration of IP cameras would be setup.
