The larger the facility being secured, the more valuable an immediate transition to IP cameras. It is not so much how many facilities but the size of each specific facility. Because of the intrinsic limitations of coaxial cable, when facilities become too large, the costs of system installation increase dramatically. Think of office towers, corporate campuses, military bases. Low cost coaxial cable runs could not solve the problem. Proprietary networks were needed.
The elimination of proprietary networks is the one advantage of IP cameras that dwarfs all others and has been driving IP cameras/encoders. This is where the business case is absolutely rock solid.
For large scale surveillance projects, you can save $1,000 to $4,000 per camera relative to analog long distance transmission systems. If you can eliminate trenching, the cost savings are even more dramatic.
It is no surprise that most of the biggest IP camera systems are among schools, corporate campuses, municipalities, the military. That’s not to say that IP cameras are not deployed elsewhere but many if not most of the biggest success stories are in applications where long distances exist between cameras.
High-resolution, Megapixel IP Cameras
Megapixel IP cameras produce high-resolution images that provide greater image detail and accuracy over their analog CCTV counterparts.
Consistent image quality, regardless of distance
Analog video signals become weaker the longer that they have to travel. Digital images need no conversion and resist degradation over any distance traveled. And in fully digital IP surveillance systems, digital images are more easily stored and retrieved as opposed to analog video tapes.
Power over Ethernet (PoE)
Increasing reliability and providing substantial savings, Power over Ethernet (PoE) enables IP cameras to receive power from the very same Ethernet cable that transports the video and audio data. No separate audio, RS-485, or electric cabling is required.
Ethernet cables on an IP network carry data commands too giving full access to camera settings and system adjustments and even camera functionalities such as pan, tilt, and zoom.
Flexible and Scalable
With analog systems a dedicated coaxial cable must be run directly from each camera to a viewing and recording station. In addition if audio is required, separate audio cables need to be run to and from the cameras. Network based IP cameras can be placed anywhere they are needed, at any time, and they can hop on the same wired or wireless network that’s already in use for communicating data.
