Introduction
The Calculator utility is a companion for American Dynamic’s Embedded Digital Video Recorder
(EDVR). The purpose of this utility is to assist users in estimating how much record time is
attainable in their EDVR systems with a known hard disk drive (HDD) size. It can also be used to
estimate how much hard drive space is needed for a target recording duration.
The user is advised to go through Sub-sections 4 Alarm Record Rate and 5 Alarm Record Mode
on pages 48 and 49 of the Installation and Operation Guide v1.54 (and later), for a full
explanation of the topics. Releases prior to this version do not contain adequate information in
these areas. These sections form the basis of the computation algorithm detailed in Section 4 of
this Calculator User Guide.
It is important to note that, starting from v1.54, the User's Guide no longer contains the Possible
Recording Time Tables. The tables previously released in v1.44A and v1.53A contain errors and
should no longer be used. They are corrected and included in this document as sections 5 and 6
respectively. The table in section 6 is applicable to v1.53A and all later releases.
Note
The compression rate of STANDARD in v1.53A and up corresponds to that of BASIC in v1.44A.
A higher compression rate is used in BASIC of v1.53A and up. This change enables longer
recording time when the camera quality and image contents give acceptable recorded image
quality.

The Calculator Utility
General Information


Applicable to FW v1.44A or 1.53A and up.
On the User Interface, red text highlights fields which are automatically selected or
calculated.

Calculate either record time on 10 GB HDD, or the HDD size to be consumed after 1
day of recording.


Calculate recording time/HD size in the presence or absence of audio.
Calculate recording time/HD size when alarm is either active or not.
Known Limitations
Issue
One quality setting applies to
all channels.
Description
EDVR provides options to set each channel’s record quality at 4
different levels of recording image; the EDVR Calculator v1.03 only
supports one global setting of record quality.
Under a special condition, the
Record Time computed by the
Calculator cannot be reached
by the EDVR. This is a
limitation of the EDVR rather
than the Calculator.
When 4 cameras are present, and alarm recording is triggered in a
single camera set up at Exclusive or Interleave alarm mode, the
alarm camera will be the only one recorded for the alarm duration. If
the alarm record rate is set at equal to or greater than the maximum
rate allowed (30 images per second (IPS) for NTSC and 25 for
PAL), this camera is expected to record at the maximum allowed
rate from the computation of Calculator v1.03.
In fact, the system will not be able to achieve this maximum record
rate. Depending on the content of the images, the actual rate can
be 3 to 5 IPS lower than the maximum. This translates into 25-27
IPS for NTSC and 20-22 IPS for PAL.

Example - Scenario 1
I have a system of 4 cameras on NTSC and no audio. I have the following setup:



Normal record at 5 IPS
Schedule1 for 12 hr of recording on alarm trigger at alarm record rate 5 IPS
Schedule1 alarms are all set to Interleave mode.
How do I use the Calculate function to figure out the record time on a 160 GB hard drive,
assuming 50% (6 hr) of the Schedule1 duration is in alarm-triggered recording?
1.
Normal Record Mode: Estimate HD space needed for 12 hours of normal recording.
11
EDVR Calculator User Guide
2.
Schedule1 Alarm Record Mode: Estimate HD space needed for 12 hours of alarm
recording at 50% of the time, or 6 hours (continued from the last section).
12
EDVR Calculator User Guide
3.
Schedule1 Normal Record Mode: Estimate HD space needed for the other 50% of
time (6 hours) when alarm is off (continued from the last section).
4.
Compute HD space needed during 24 hours from steps 1–3 above:
HD space
= (6 + 3 + 3 +/- 0.7) GB
= 12 +/- 0.7 GB
5.
Compute recording time attainable on a 160 GB HD:
Record Time = 160/12.7 to 160/11.3 Days
= 12.6 to 14.16 Days
= 13.38 +/- 0.78 Days
13
EDVR Calculator User Guide
Example - Scenario 2
Everything is set up the same way as Scenario 1 except that Schedule1 alarms are all set to
Exclusive mode. How do I do the calculation now?
1.
Normal Record Mode: Estimate HD space needed for 12 hours of normal recording.

2.
Schedule1 Alarm Record Mode: Estimate HD space needed for 12 hours of alarm
recording at 50% of the time, or 6 hours (continued from the last section).
15
EDVR Calculator User Guide
3.
Schedule1 Normal Record Mode: Estimate HD space needed for the other 50% of
time (6 hours) when alarm is off (continued from the last section).
4.
Compute HD space needed during 24 hours from steps 1–3 above:
HD space
= (6 + 12 + 3 +/- 1.1) GB
= 21 +/- 1.1 GB
5.
Compute recording time attainable on a 160 GB HD
Record Time = 160/22.1 to 160/19.9 Days
= 7.24 to 8.04 Days
= 7.64 +/- 0.4 Days

The Computation Algorithm
Normal Record Mode
Alarm Record Mode
Alarm Camera: Cameras are in the alarm state.
Non-Alarm Camera: Cameras are not in alarm state.
If CH1~CH16 are set to the same Alarm Record Mode, the expected record rate can be
derived from the table below.

Alarm record rate is 60 IPS. A = 60
Number of active alarm cameras is 3. N = 3
We can calculate the IPS for cameras 1, 2, 3. The IPS is 60/(3+1) = 15
Rest IPS is B. B = A/(N+1) = 60/(3+1) = 15
Number of active alarm cameras with Double mode setting is 2. P = 2
Number of other cameras is 4. R = 4.
We can calculate the IPS for the double mode cameras 5 and 6.
The IPS is 2*B/(2P+R) = 2*15/(2*2+4) = 3.75
We can calculate the IPS for the other cameras 4, 7, 8, 9.
The IPS is B/(2P+R)= 15/(2*2+4) = 1.875

Possible Recording Time Tables for EDVR v1.44A
The quality of each image will lead to a range of picture sizes, depending on the quality of the
camera and the image content. The ranges are:




BEST: 38K ~ 42K
HIGH: 30K ~ 34K
STANDARD: 22K ~ 26K
BASIC: 14K ~ 18K
The center points of these ranges, 40K for BEST, 32K for HIGH, 24K for STANDARD and
16K for BASIC, are used to compute the estimation of recording period in the following
tables.
Note
Depending on the picture content and the camera quality, a variation up to 5%, 6%, 8% and 12% for
the four quality settings may be encountered in reality.
