Tips on Choosing the Best IP Network Video Recorder
When it comes to quality video images, IP-based video surveillance systems have
become quite popular. You can either choose an IP camera with a VMS (Video
Management Software) or a dedicated NVR (Network Video Recorder) for setting up
the new system. As far as commercial or professional surveillance applications are
concerned, you can enjoy uninterrupted video recording and video footage
management with an IP based network video recorder.
The network video recorder integrates video recording, front end management as
well as network transmission. A NVR can be categorized by the number of channels
it supports. Mostly 4, 9, 16, 24, 32 and 64 channels are used in video surveillance
systems nowadays. A maximum of 128 or 256 channels video recording and
management can be used by some of the top quality network video recorders.
There has been a considerable rise in demand for NVRs as IP surveillance systems
have become popular. Today, you get to select from different NVRs.
Here are a few factors to consider when choosing a quality network video recorder:
You need to look for the best recording resolution and channels. You can opt
for 1080P which is a full high definition resolution. This will be quite useful if
you are setting up a full HD surveillance system. You also need to consider
how many IP cameras will be connected to it along with the scope for
expansion in future. Let us understand this with an example. If you are
currently planning to install 4 IP cameras in the system but you may want to
expand it in few years to cover monitoring blind spots, it is better to choose a
network video recorder with 8/9 channels.
Second factor to consider when selecting the right NVR is interoperability. It is
recommended to use a NVR that has good interoperability. Even appropriate
HDD storage interface is required. This is because mega video storage space
is needed in IP based video surveillance system which is different from the
conventional CCTV DVR system. This space is used for recording high
definition resolution video footage. The user needs to estimate how much
video storage space will be needed in order to achieve the desired recording
Another factor to consider is the alarm I/O and audio I/O interface. The NVR
you choose should have these interfaces besides the primary recording and
playback function. Through these interfaces, it becomes easy for the network
video recorder to work with other security devices such as access control,
intrusion detection sensors and the burglar alarm system. Two way audio
broadcasting can be ensured through the audio I/O interface.
In surveillance, even video analytics matter. It is a software that is meant for helping
users review the growing hours of surveillance video that a security guard may
never have time for watching. By using video analytics, the video surveillance
system can be made more efficient. It also helps in reducing the workload on
management and security staff.
