The IP Based Home Security Camera That You Can Do Yourself:
As an an alternative to the traditional CCTV system, individual IP cameras can easily be added to your home network. These cameras are connected to your local network just like any other network device. They would connect using a CAT5 cable directly to your networks router or switch .

Or
You can use them for simple internet viewing of your property or they can be used in conjunction with recording software that you install on your computer to turn it into a network video recorder (NVR).
The components of any IP based security camera system would include:
1. IP based cameras
2. CAT5 network cable
3. a Power Over Ethernet Stitch to connect the devices to your network.
4. NVR recording software
5. a system to install the software on
Some traditional CCTV solutions, such as the PC based solutions from GeoVisoin, are actually a "hybrid" system, meaning they can accept a combination of CCTV and IP cameras running on the same central digital recorder. Keep in mind that IP cameras are significantly more expensive than standard CCTV cameras but can come in handy in certain situations where connecting a camera to a network drop is easier than running a new coax cable for an analog camera on a CCTV only system.
Keep in mind that many IP cameras have their recording software sold separately, while other brands of higher end IP cameras will have professional grade NVR recording software included. Despite the potential for added software costs and the fact that IP cameras can run two to three times the cost of their CCTV counterparts, the flexibility of adding just a few cameras using existing CAT5 network cable can often more than make up for the initial cost difference.
Another reason people chose IP cameras is their picture quality. IP cameras operate a resolutions that are more in line with modern PC displays. That means they will start out recording at resolutions around 1280 x 960. Compared to CCTV based DVRs that commonly record at resolutions as low as 320 x 200. You should understand however that higher resolutions can come at a cost. That being it becomes harder to record at high frame rates as the individual frame resolution increases. Also a larger frame resolution will mean that each image takes up more space on the systems hard drive. The exact degree to which these factors will impact any system is difficult to determine in advance. But should the system have only a few IP cameras their overall impact would itself be kept to a minimum.
