Camera Video Storage
DVR, NVR or TVI?
DVR's often interface with analog cameras and they have a restrictive number of cameras which connect directly in the back of the unit. DVR's that have both a limited image collection process but may have the capacity to implement or the more recently released HD cameras. However, the DVR may not be able to take advantage of all of the features of an HD camera. DVR's often have lower capacity for storage and cameras are usually in a single site or building.
The traditional DVR is currently at the end of its life cycle due to advances in camera technology.
Network Video Recorder (NVR)
Currently we offer two different NVR's. One with Analytics and the other for use in surveillance systems that use, and thus require, large video storage capacity. The ever growing megapixel camera lenses, now 4k aka HHD simply require greater more storage.
With video storage requirements becoming larger, NVR's have adapted to include the added storage by allowing multiple drives, drive bays or drive type replacement known as Purple Surveillance.
TVI recorders answer the problem of existing camera system upgrade migration paths. Continue using your existing cameras while adding Megapixel cameras as needed either on one site or multiple locations.
TVI recorders usually have Video Management Software (VMS) which improves multiple camera viewing to often a drag-and-drop options. Our TVI recorders have VMS software, Smart phone App's and can even be used with your browser. All that is needed is a static IP address that does not change.
Like all electronics, today's DVR's are quickly retiring from use in the business sector. The advancement of HHD camera technology and the use of Megapixel cameras have forced the replacement of DVR's.
The improvements in surveillance systems places greater demands in video storage so a DVR upgrade probably is in your future. But the replacement is well worth the costs as HHD cameras, aka 4k give twice the image data than an older HD camera.
NVR Recorders came onto the surveillance horizon with the implementation of the megapixel cameras. Megapixel cameras posed a problem, how to store the ever increasing video storage requirements.
They also posed a secondary problem, with greater storage came heat generated from multiple drives writing the data to the drives. Today it is not unusual to have 3 or 4k megapixel cameras, and depending on size that storage can increase beyond 4TB drives of video storage.
TVI, short for HD-TVI is defined as the High Definition Transport Video Interface. Why TVI rather than a NVR or DVR? Cost for one. The migration path for a DVR is a TVI recorder. Another advantage of TVI recorders is that you can continue to use your existing camera investment and add High Definition security cameras which provide for clear images and more detail.
Another advantage of TVI recorders is that they can convert HD digital signals used by HD cameras to digital signals. This allows for greater distances for those signals and places cameras at further distances.
