A Field Study Using CaptureSync

In a now-famous experiment initiated by the Washington Post, world-renowned violinist Joshua Bell performed undercover in a busy metro station. Using a priceless Stradivarius violin, Bell performed music that he normally plays in front of large concert audiences around the world. The result? Hardly anyone paid much attention to the violinist, or tossed many coins into the open violin case by his feet. The experiment provides a fascinating insight into the importance of context in our experiences of the events around us.

The performance was recorded, but only by a single low-quality camera. What if we wanted to record the experiment properly, from multiple angles, in order to analyse every aspect of the event and people’s reactions? This is the kind of task that CaptureSync is perfect for, and the setup of this hypothetical recording is detailed below.

Raspberry Pi Camera to SecuritySpy

Below is a guest post by one of our users, Wayne Jacobsen, who is using a Raspberry Pi computer to turn a USB webcam into an IP cam that can stream video to SecuritySpy, in order to expand his Mac video surveillance system. Wayne is an Art Glass artist  – you can see some of Wayne’s work on Pinterest. Wayne has contributed the following description of his setup:

The Raspberry Pi can make a nice security camera in a SecuritySpy system with surprisingly little effort. I wanted a way of seeing what temperatures my kilns were, especially when they were cool enough to open and take the glass out. I had a Raspberry Pi (RPi) equipped with USB WiFi dongle and an old Logitech QuickCam Pro 9000 webcam sitting around from my old PC days. A little research on the web led me to many ways to use the RPi with the webcam and I used the instructions on this page as the basis of my setup. Someone has done all the software development work for us in a program call Motion.

SecuritySpy and ONVIF

SecuritySpy is our flagship video surveillance software product for Mac OS X, and as of version 3.2, SecuritySpy supports the ONVIF protocol. Here are the answers to some common questions, and information about this new feature.

What is ONVIF?

ONVIF is an open industry standard for IP-based video surveillance products. In the past, SecuritySpy would have to be pre-programmed with profiles for each camera it supports, containing information about the supported streaming formats, audio capabilities, communication ports, resolutions, frame rates, Pan/Tilt/Zoom features etc. This is inconvenient and time-consuming for us as developers, and also bad for customers because there is an inevitable delay between a new camera coming on the market and an update to SecuritySpy to officially support it.

With ONVIF, all this information can be obtained from the camera automatically. Therefore, any new ONVIF-compliant camera hitting the market can be immediately used with SecuritySpy using the ONVIF setting built into the software.

Adding a Camera Unknown to SecuritySpy

We have an extensive list of cameras that are known to be compatible with SecuritySpy. All these cameras have profiles built into SecuritySpy, making for a quick and easy setup in most cases.

However, it’s a fast-changing market and new cameras are continuously being released. While we do our best to release frequent updates that support these new cameras, it’s a difficult task. You may find yourself intending to use a particular camera that is not yet on our list – this blog post will show you how.
