Benefits of IP Surveillance
Remote Monitoring & Storage
With traditional analog CCTV systems, operators can only access their security cameras from a lone central monitoring location. With network cameras, it’s a whole new ballgame. IP-based surveillance systems allow remote access from anywhere, at any time. How do they do this? By capturing and distributing high-quality video over an IP network or the internet. Video footage can also be stored digitally at remote locations. Users
can then access the footage, and even control cameras remotely from any authorized computer. Some network cameras also allow for remote monitoring via cell phone or PDA. In most instances, all it takes is a standard web browser to view live video.
Network cameras have the potential to deliver extremely sharp and detailed video images. A number of factors including the image sensor, encoding chip, lens type, and pixel-count help to determine the quality of video images captured.
An IP camera generally comes equipped with either a CCD, CMOS, or a megapixel sensor. CCD sensors offer excellent image quality and light sensitivity but consume more power than CMOS sensors. CMOS sensors enable more integration possibilities and have a faster readout which makes them ideal for applications requiring high-resolution images. Megapixel sensors provide the highest image resolution with the greatest detail, but offer less in the way of lowlight performance. A camera’s encoding chip can also play a factor in the level of image quality. IP camera models offer varying levels of encoding performance, and the encoding chip helps determine the level of image quality based on format, compression, and resolution for video streams.
Image quality is affected by the type of lens you use as well. The camera lens controls the amount of light passing through to the image sensor, working to ensure properly exposed images. Many IP cameras support interchangeable lenses to provide the highest quality images for different types of surveillance applications.
When we mention pixel-count, we’re basically talking about the maximum image detail that a network camera can provide. While analog cameras must meet NTSC/PAL specifications that can limit their abilities in terms of extreme image detail, the possibilities with IP cameras are limitless, depending on the model of course. This is evidenced by the performance of megapixel network cameras which feature a high pixel-count, and capture exceptionally detailed video images.
One of the great things about IP surveillance systems is the fact that they’re easily expandable. Any time your surveillance requirements grow, you can scale your system by simply adding new IP cameras to your existing network. It’s just as easy to increase your storage capacity. Plus, you don’t have to worry about costly, complicated cabling schemes every time a new camera is added. With an IP surveillance solution, you can install additional IP cameras the same way you’d add any other network device.
