O
ne of the greatest myths about CCTV is
that end users are more than happy to
pay for systems which record time-lapsed
video. In the past, the limitations of magnetic
tape forced a situation where multiplexed time-
lapsed video was a necessity. As the
technological barriers have been eroded, so the
expectations of CCTV have been raised. Indeed,
if you ask most end users what they want from
CCTV, it would be high resolution images, in real
time, all of the time! It’s when the cost of that is
realised that compromise starts to creep in.
In recent times, manufacturers have looked
to deliver recording solutions that offer higher
frame rates. With the advance of digital
technology, it becomes increasingly obvious
that real-time is not only desired, but in many
applications it is demanded. To not meet this
demand would be to lose out on vital contracts,
and so frame rates have gradually increased.
The main focus of the test is to consider
whether these machines are capable of
delivering higher levels of performance than
standard DVRs, which are very widely available
in the CCTV sector. If so, does the processing
capability deliver the specified performance, or
do the units creak when put under pressure?
Samsung SRD-1670DP
The SRD-1670DP from Samsung is billed as a
real-time DVR, and supports up to 16 video
inputs with loop-throughs via BNC. The main
video output is via BNC, VGA or HDMI. There
are four spot monitor outputs using BNC.
The unit has some serious processing power.
It also offers a high level of flexibility, featuring
10/100/1000 LAN connectivity, alongside RS-
485 and RS-232 data connectivity. The unit also
features three USB ports and two external SATA
ports. Two of the USB ports are conveniently
located on the front of the unit, with one on the
rear panel.
The DVR supports two-way audio with 16
inputs and 1 output. The inputs are handled by
way of four phono sockets, with the remaining
inputs connected via a D-Sub socket. The audio
output is also phono. The unit also boasts 16
alarm inputs and 4 alarm outputs. A DVD
rewriter is included.
