IVA 4.0 Requirements | en 2 Requirements 2.1 Setup 7 The easiest way to set up IVA 4.0 and IVA 4.0 Flow is using the Configuration Manager program. This must be installed on a Windows PC that can communicate with the respective device over a network. You will find a current version of the Configuration Manager program on the CD received when you purchased the license. Operational requirements for the Configuration Manager program can be found in the documentation supplied.
en | Requirements IVA 4.0 2. Select SETTINGS > Advanced Mode >Service > Licenses. Make a note of the installation code — the copy-and-paste function is supported. Requesting Activation Keys 3. Open the following Website from any PC: https://activation.boschsecurity.com/ You will find a direct link to this Website under Tools on the IVA 4.0 CD. The Bosch Security Systems Software License Manager user interface will appear. The page appears in English only. 4. If you already have an account, log in.
IVA 4.0 Requirements | en 9 13. Close the window. IVA 4.0 is now activated. The activation key can no longer be seen. Upgrade from IVA 3.5 If you have already licensed IVA 3.5 for the device, you simply need to upgrade the firmware of the device to version 4.0 or higher. The license for IVA 3.0 is then automatically changed to an IVA 4.0 license. Relicensing is not necessary. You obtain the current firmware from your customer service or from the download area on our Internet site.
en | Requirements IVA 4.0 If you are specifically looking for moving objects with certain color properties, take the following into consideration: – An object is almost never displayed in a consistent color in the image data. Pixels on the outer edge of a detected object in particular often contain the color information of the background and not the object. Objects such as automobiles comprise a variety of parts (body, windows, tires).
IVA 4.0 3 Configuration | en 11 Configuration IVA 4.0 and IVA 4.0 Flow are set up using the Configuration Manager program or via the Web browser view of the device. You must move the camera to the required position first in each case. When using VG4 AutoDome, the individual presets must be specified before configuring IVA 4.0 for each preset. All of the settings you make relate to the selected camera position. This means that you must reconfigure IVA 4.
en | Configuration IVA 4.0 7. Select IVA 4.0 or IVA 4.0 Flow as the Analysis type. If you change the analysis type, the motion detection and tamper detection parameters revert to the default settings. As soon as the analysis becomes active, meta data is generated and, depending on the configuration, additional information is overlaid on top of the camera image — an object bounding box for example. 8.

IVA 4.0 4.5.8 IVA 4.0 | en 35 Removed object This task generates an alarm event if an object is detected as removed in a certain area (for example, due to theft). The area is defined by a field in the camera image. It is assumed that an object has been removed if changes are detected in the background following movement within an image. First Step - Define the Field X Select one of the fields. To do this, use the list field or click a field in the camera image.
en | IVA 4.0 4.5.10 IVA 4.0 Entering field This task generates an alarm event if an object enters an area. The area is highlighted by a field in the camera image. The alarm event is triggered if an object that was previously detected outside a field crosses the field boundary. First Step - Define the Field 1. Select one of the fields. To do this, use the list field or click a field in the camera image. You can also create a new field, edit an existing one or select Whole screen. 2.
IVA 4.0 IVA 4.0 | en 2. 37 Debounce time [s] If a value other than 0 (zero) is selected, the alarm event will not be generated until the object has moved or been outside the field for the specified period at least.
