Performance

Frame Skip This option determines how many frames

are skipped in recorded events. By default this is set to

0 which doesn’t skip any frames and means that every

captured frame is saved. Entering a number in this field

defines how many frames are skipped between every

recorded frame. For example, if 2 were entered in this field,

two frames are skipped in between every single frame

recorded.

Image Buffer Size Determines how many frames are held

in the image buffer. By default, this is set to 40.

Replay Image Buffer Defines the total number of frames

for the replay image buffer. 1000 is the default value.

Warm Up Frames Specifies the number of frames

processed before analysis occurs. 25 is the default value.

Analysis & Recording

Reference Image Blend % Every analyzed image is a

composite of previous images and is formed by applying

the current image as a certain percentage of the previous

reference image. The value entered here determines the

percentage of the previous image used. By default the

value is set to 10%. A higher value would make slower

progressing events less detectable. Typically if this

number is modified, it should be adjusted down.

Alarm Frame Count Specifies how many consecutive

alarm frames must occur before an event is generated. The

default value of 1 ensures that any alarm frame generates

an event. Although a value of up to 16 may be entered

here, typically anything larger than 3 or 4 will not be

useful.

Event Frame Pre Padding When motion is detected, this

is the amount of frames included in the recording before

the motion occurs. By default this is set to 30.

Event Frame Post Padding When motion is detected, this

is the amount of frames included in the recording after the

motion occurs. By default this is set to 30.

Recording Clip Length Defines the maximum length of

a recording clip in seconds. The default is 600 seconds (10

minutes).

Timestamp

Timestamp Label Format The timestamp label on the

image is defined here. If the field is left blank, there will be

no timestamp on your images. Below is a list of strings that

can be used to create custom timestamp information. The

strings are case sensitive. You can separate the strings with

dividing characters such as spaces, slashes, dashes, and

colons.

X Location The X value adjusts the position of the

timestamp on the image to the left or right. A value of 0

positions the timestamp on the left side of the image.

Y Location The Y value adjusts the position of the

timestamp on the image to the top or bottom. A value

of 0 positions the timestamp on top of the image.
