EDVR Calculator User Guide
4
1. 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.
