TECHNICAL INFORMATION

EventCam

Application and Tricks

1 Introduction

In this document we will elaborate on the applications of the EventCam as well as

giving a step by step configuration for these applications. Keep in mind that this is

not an instruction manual on how to do an initial setup of the device. This information

is available in the Device operating instructions. This document is application based

setup, optimization and trouble shooting. As products become more versatile, they also

become more complex.

This document aids in bridging this gap. Information not in this document is available

on the SICK Internal Intranet and includes EventCam product training, application and

setup videos, troubleshooting guide and firmware information.

2 Applications

Typical applications for the EventCam are:

1. Failure analysis in processes, e. g. grip‐

ping, gluing, screwing, etc.

→ For process optimization and higher

machine uptime

→ For faster and easier machince set-up

by better alignment of sensors or machine

components

2. Diagnosis of laser scanner trips, e. g. in

Automotive Industry and AGV/AGC applica‐

tions

3. Quality documentation in logistic

processes or food industry

7 Processing time

Calculation of total event processing time:

Time for image processing

+ image or video compression

+ zip container

+ writing on SD card or FTP transmission

= Total event processing time

NOTE

Thumb rule:

2 * event time = total event processing time

Figure 9: Processing time

Which time can I expect for event processing after the event?

Table 1: Event processing time

In picture mode In video mode

Resolution Time per picture in

the event

QSXVGA 0.5 s

1080p 0.25 s

720p 0.1 s

SVGA 0.05 s

Resolution Time per second of

the event

1080p @ 30 fps 2.2 s

1080p @ 15 fps 1.1 s

720p @ 45 fps 1.7 s

720p @ 15 fps 0.6 s

SVGA @ 65 fps 1.3 s

SVGA @ 13 fps 0.3 s

Example: Video with 1080p @ 15 fps, 10 s before trigger and 5 s after trigger signal:

Processing time = 1.1 x (10 s+5 s) = 16.5 s

Additionally, 1s per 15 MB event data has to be added for zip container compression.
