Record rate
The record rate is the amount of pictures recorded to disk in a second, or pictures
per second (PPS). This is a system wide figure, so whether 1 or 16 cameras are
recorded, the record rate remains the same. The update rate per camera can be
worked out using the record rate:
Update rate = No. of cameras
Record rate
A table of common record rates can be found in Appendix 2.
Hard disk capacity
Analogue VCRs use 3-hour tapes which re c o rd a finite number of images. Unlike a
VCR, the number of images that can be re c o rded to a digital multiplex re c o rder can
be increased by using a larger capacity hard disk. Digital Sprite 2 has a range of hard
disk sizes, at the time of writing 80, 160, and 320GB disk sizes are available.
Using a larger hard disk will allow image quality, recording rate, or recording time
to be increased. For example, an 80GB disk can record for 8 days at the default
settings (24-hour time-lapse mode at S-VHS quality).
Tip: As a rule-of-thumb recording at the default settings* will use 10GB of
storage per day, i.e. an 80GB unit will record for 8 days.
Calculating recording time
Digital Sprite 2 calculates the recording time automatically when the record rate
and image quality are entered. Alternatively, an interactive record calculator is
available for download from our web site:

* 24-hour time-lapse mode, 6PPS, and S-VHS quality images, 18KB
Digital Sprite 2 can be installed in as little as 4 steps, and being plug-and-play,
cameras will be detected and recorded automatically.
STEP 1. Connect cameras
Connect cameras to the video inputs marked VID1 to VID9 (9-way unit) or VID16
(16-way unit). Use the bottom row of connectors for looping through to other equipment.
STEP 2. Connect monitors
Connect the video output marked MON A to the Main monitor (digital playback
and multiscreens).
Connect the video output marked MON B to the optional Spot monitor (analogue
full-screen images).
STEP 3. Connect the external devices
If external devices need to be connected to Digital Sprite 2, go to the next section
– ‘Connecting external devices’, before proceeding to Step 4.
STEP 4. Connect power
Once the Digital Sprite 2 is in its final position and all external devices have been
fitted and powered, connect the PSU to the rear of the unit and apply the power.
The power-up procedure may take up to one minute before Digital Sprite 2 can
be used.
will now record all cameras in a 24-hour time-lapse mode
without any further programming!
