New UHD 4K Systems

Category : General 4K UHD

There is increasing attention being focused on the new ultra high definition surveillance systems by many top manufacturers. Like previous generations of CCTV video security, The first generation has taken longer than expected for completion and actual deployment is still hazy. The problem is mainly on the recorder/NVR side since many solutions have limited resources and were not designed to handle the sheer mega amount of data produced by ultra high DEF. However, cameras are widely available in many different forms and price levels. VMS platforms that claim to already except this new 4K format have proved difficult to deploy in the real world. The massive data streams produced by eight megapixel cameras at full frame rate prove problematic for networks and video management systems alike. Having network engineers on hand is always recommended. 4K might not seem like an earth shattering innovation, but it is a huge jump from the common 1080P standard utilized heavily in the video surveillance industry today. 4K systems are actually four times larger than 1080P and will also consume four times the amount of storage. For example if a 1 TB hard drive was lasting for days with the previous 1080P resolution, it will last only one day with a 4K UHD system.

But each new day offers new hope. Hard drive sizes have also increased dramatically in the last few years. It is not common to find 6TB , 8TB or 10TB or increasingly lower prices. Most high-end Cctv systems easily except these larger format hard drives that can not only store more data are actually designed to last longer with specific components and programming design for the video surveillance industry. 

Recording 8 megapixel security cameras is not only tough on storage it is also difficult on the network infrastructure needs to carry the data. Most common networks are not capable of supporting 4K security cameras especially if more than a handful a writing the same backbone. It is crucial to determine existing infrastructure, new network creation, and all of the options available like fiber optics or gigabit LAN technology.
