A lot of clients approach Charleston Security Systems and ask us,
“Should we go with IP cameras or should we stick with our analog DVR camera system?”
Our answer: “It’s all about your network.”
DVR Camera Systems (Analog) vs. NVR Camera Systems (IP)
DVR camera systems rely on analog signals (via coaxial cable) being transmitted from cameras (powered by separate power cord and power supply) to a digital video recorder (DVR). The signal is received by the DVR which then processes it into a digital format that is recorded in a hard drive within the DVR. The video then can be accessed locally or remotely using embedded software and/or mobile viewing apps.
NVR camera systems use digital signals sent from IP cameras to a Network Video Recorder (NVR). The processing of the video from analog to digital takes place at the camera itself rather than at the hub where all the cameras converge to. This digital feed is then transmitted using a network cable (as opposed to the coaxial cable) which, in most cases, also powers the camera (Power over Ethernet or POE). The NVR is integrated into your local IP network that can enable it to be accessed remotely.
How Robust Is Your Network?
For those with robust networks already wired in their facility or site, an NVR may be an easily integrateable solution for you. This would mean you would have to rely more on your IT staff or your security company’s IT staff in case any changes or maintenance would be required.
For those that don’t have an extensive network already integrated into your building/site, an NVR still could provide a solution, however in most cases, a DVR camera system is the more simple, direct and reliable solution.
How Do You Want Your Network Managed?
Many home and business owners don’t want their existing networks interfered with; thus a DVR camera system installation offers them the best solution.
As stated previously, an NVR camera system also will require you to have a dependable IT staff available to keep you up and running.
