Special Features: Though DVRs might not appear to be the most advanced security camera solution, they can
be configured with a range of different features. Motion detection and time stamping capabilities, for example,
means surveillance staff no longer have to work round-the-clock or sift through hours of footage to find a specific
incident.
Challenges of DVR Camera Systems:
Minimal Flexibility: Given that DVR systems need to be located close to a power source, businesses sometimes
have limited options for installing them onsite. Because DVR security recorders do not make use of network
connections, footage also has to be reviewed wherever the storage device is located.
Maintenance Fees: If a DVR malfunctions, it’s a hardware issue—not a software issue—and can therefore be
very expensive to fix or replace.
Clunky Wiring: Unlike NVR systems, which can be configured wirelessly, all security camera DVR solutions
require coaxial cable connections. In addition to not supporting audio, these cables are large and therefore hard
to install in tight spaces and are unable to supply power (DVR systems transmit signals only). This means extra
wires are always needed to ensure the cameras can operate.
Low Image Quality: Although DVR camera systems are cheaper than other security options, they output a much
lower picture quality than hi-res cloud and hybrid cloud cameras. Business owners and surveillance teams will
need to determine whether the cost savings are worth sacrificing picture clarity.
Storage Capacity: DVR camera systems cannot connect to the internet, via ethernet cables or wifi. And because
of that, storage capacity is much lower than systems that can make use of cloud storage, like NVR camera
systems do.
