COMPARISON OF IP CAMERA CLOUD STORAGE LICENSE
This is especially useful when trying to read a license plate or recognize a person.Įxpansion of a CCTV system can be costly due to the typical limitation of a DVR in a CCTV system. The more pixels you have in an image, the more you can zoom in before the image begins to break up. This allows for improved investigative research upon viewing recorded video after an incident. Digital zoom gives the user the ability to “digitally” zoom in to both live and recorded video to see the image in more detail. The highest resolution attainable for an analog camera is D1.ĭigital zoom is another feature of an IP camera system that is not available in most CCTV systems.
The table below shows common resolutions for both analog and IP cameras. It can take as many as six analog cameras to view the same area as one, 2 megapixel IP camera. This means you can reduce the number of cameras required to view a specific area by using IP cameras, therefore reducing the total cost of ownership. The higher resolution of IP cameras results in a much larger field of view when compared to analog cameras. IP cameras today have a much higher resolution than CCTV cameras. By using a PoE switch or injector, an IP camera can be powered and transmit video over a single cable, thereby reducing the cabling cost compared to CCTV.Īnother IP camera anvantage is that the capabilities of IP far surpass that of an analog system. CCTV uses coax and a power cable while an IP camera uses standard network (Cat 5e or Cat 6) cabling. One of the factors helping to reduce the cost of an IP system is the cost for cabling. In fact, many studies show that the total cost of ownership of a CCTV system is actually higher when compared over the life of the system. However, that is rapidly changing as IP cameras and storage devices have shown a continued decline in pricing. CCTV systems, in the past, have had a lower initial price point when compared to IP systems. When comparing CCTV vs IP camera systems, both have advantages and disadvantages. The IP system has the added benefit of using the network devices which can expand the range of the IP cameras beyond that of a CCTV system. IP cameras convert the video signal into IP packets to be transmitted over the data network or internet to a network storage device such as a server, NAS, or by storing on board the camera. CCTV systems convert the video signal to a format that can be used by televisions, VCR’s, or DVR’s.
Both CCTV systems and IP systems transmit video to the desired destination. There are basically two types of video surveillance systems, CCTV (closed-circuit television), also known as analog, and IP cameras, also known as network cameras. IP Cameras are the largest technological advancement since cameras have been produced.
