Cell Phone Viewing compatible with the
following:
Digital Video Recorders (DVRs) are the devices
used to capture images from your security cameras. Just as a television DVR captures your
favorites shows, these Security DVRs capture images (and audio if applicable) from your security
cameras. Please select from the categories listed above for specific
channel requirements, browse our entire inventory or call us for additional assistance..
All
of our DVRs are Professional Grade Security Recorders used for
residential,
business and
commercial applications. These units offer user-friendly operation,
remote viewing through web browsers, cell phone access,
real-time operation (30FPS recording and viewing of live pictures),
superior dependability and advanced features over
most DVRs sold in retail, hardware, warehouse and club stores.
What to know
when selecting a DVR
What does FPS mean? This term is used to describe the number of Frames
Per Second (FPS) a single channel is displaying or recording. The industry
standard uses 30FPS to indicate 'Real Time' when recording and
displaying moving video. Typically 30FPS is the maximum frame rate
that can be recorded per channel - at a specific resolution format (see chart below).
However, FPS can be reduced down to 1FPS recording if desired.
- FPS Display and FPS Record are two different
factors: When an 8 Channel DVR is shown as being a 240/240 DVR,
it is both displaying and recording in Real Time: 240FPS ÷ 8 Channels =
30FPS per channel versus a 240/120 DVR which is displaying live images at
30 FPS and recording at 15FPS per channel: 120FPS ÷ 8 Channels = 15FPS
recording per channel.
- Why reduce FPS? As a way to save on hard drive space. When you reduce FPS but but tie it to an alarm or motion detection setting on the DVR, these events can be set to trigger an increase in FPS when needed. In order to receive the highest analog image possible you can either purchase one of our systems which records at a full 30FPS at D1 (typically used for high security applications) or reduce the frame rate on our other security recorders.
What is CIF
recording resolution format? A commonly used term when discussing video recording
resolution. CIF stands for Common Intermediate Format and is
used to describe the horizontal and vertical resolutions in pixels in a
video signal. The chart below will give you the most often used
recording formats. A 4CIF recording format means that 704 pixels will
be filled with video across 480 lines versus CIF recording with 360 pixels
filled with video across 240 lines. The more pixels per images, the clearer or higher the viewing resolution is.

Watermarked Video - marks the date & time on the USB or DVDRW
to provide the time of the incident and authenticates the information.
When given to police or shown as courtroom evidence, a watermarked
video can be admitted as evidence, whereas an un-watermarked video can be
tampered with.
What
is S.M.A.R.T. Technology? S.M.A.R.T.
(Self-Monitoring, Analysis and
Reporting Technology) is a technology built into most modern hard
disks. It enables the Security Recorder / DVR to predict the future
failure of hard disk drives. If enabled, it lets the user query the
hard drive(s) about it's
health and performance and can predict possible future failure of hard
disk
drives so they can be replaced before any data is lost or damaged.
