When you talk about recording for CCTV analog cameras DVRs allow users to convert their CCTV analog video to digital video. This allows for remote video monitoring, far more storage capacity, and provides fast and easy search capabilities. Digital video recorders help to bring CCTV analog cameras into the modern digital age. By converting your video to digital, you open up a whole new world of functions to manage and view your surveillance camera feeds.
Not long ago VCRs were used by most security surveillance systems to record their cameras. VCRs would record full time or often would record video based on triggered events, while recording the video onto a cassette tape that typically would record at a rate of 25 frames per second. This was the most advanced system for the times. As time went on we quickly learned that no matter the type of security cameras you use, storing recorded video on VCR tapes is simply not great strategy. Tapes do not hold much information, take up space, and they are simply very hard to search through when trying to pinpoint a specific video event.
This leads us to the digital video recorder (DVR).
What exactly is a Digital Video Recorder?
Digital Video Recorders (DVRs) are typically a standalone device with its own RTOS ( real time operating system) designed specifically for recording security video cameras. They contain the video storage, software, and record video to hard drives instead of tapes, all in a single unit. Modern day DVRs accept analog video cameras and converts the video to digital. It’s a simple, cost-effective method of bringing an analog system into todays technology. Newer DVRs also record newer HD cameras on the market. These DVRs work much the same way as they do with analog cameras except they work with HD cameras instead of analog.
DVR Recording Benefits
DVR video recording is an excellent method to migrate your current analog CCTV into a digital security solution . This really is a low-priced alternative that delivers several advantages to individuals who currently own analog video cameras, or perhaps, aren’t still willing to make the shift to a completely HD or IP-based security system .
In past times, traditional CCTV systems could merely broadcast video to an individual monitoring station or monitor, but that’s not the situation when working with a DVR. The majority of digital video recorders nowadays enable you to gain access to your video camera footage remotely over the web. By linking your analog surveillance cameras to a DVR, it is possible to monitor your cameras instantly from any kind of PC with internet access, as well as from compatible smartphones or tablets.
A short time ago, nearly all security video systems could simply record to VHS tapes . Recording to tape has a plethora of disadvantages. For starters, the cassettes are large and occupy too much space. Furthermore, attempting to lookup the recorded video footage on analog tape is generally a waste of time. With DVRs, your current video footage is transformed from analog to digital, in order to store considerably more video without the mess , and it’s considerably faster as well as simpler to sift through archived video footage.
To take full advantage of accessible storage space, DVRs deliver several different modern compression methods. Typical compression types consist of MPEG-4, Motion JPEG, and H.264 . With video compression, your data file sizes are decreased as far as possible without compromising video quality .
Digital video recorders (DVRs) offer protection with passwords so only those people you authorize are able to access the DVR menu, video footage or playback from remote locations.
Converting from Analog to HD Surveillance Cameras
There simply is no secret that the future of CCTV surveillance cameras is HD video based solutions, but this does not mean that you must throw away existing CCTV analog cameras when you make the transition. The latest in CCTV security products such as hybrid DVRs allow you to have a future-proof HD surveillance system while continuing to have analog security cameras you have installed already.
Hybrid Analog DVRs
There is quite a difference between a standard DVR and a hybrid DVR security system. A standard CCTV DVR limits you to only using analog CCTV cameras. The video from the analog cameras are sent to the DVR it is then converted to digital signal. A hybrid DVR system, provides you with the option of using both HD IP cameras as well as analog cameras, all working together on the same system.
Hybrid DVR Advancements
As we mentioned earlier Hybrid DVRs are very unique in how they support both CCTV analog cameras and IP cameras. New systems are starting to offer Tribrid technology. These systems will allow analog CCTV cameras, IP cameras and HD-CVI cameras on one system. Making your security DVR as future proof as possible. These levels of flexibility are simply not available with standard DVRs, that only service analog cameras. Hybrid DVRs help to make your transition from analog to HD surveillance very easy. Since the Hybrid supports both camera technologies, you simply are not restricted to your camera choices. This allows for an easy to shift towards an HD based solution while maintaining your lower-cost CCTV analog cameras when need be.
