A single region of interest image for Telraam S2

Telraam S2 devices are built in a robust way, with a fixed camera, meaning that there is no reason to monitor the field of view daily after the initial region of interest (ROI) was set either automatically by the camera, or manually by the user or network administrator. After every ROI change a single low resolution (112-by-112 pixel) image is saved in the system of the selected ROI, which can serve as a reference of what part of the street is actually monitored by the Telraam S2 device.

New images are only pulled from the camera when a ROI change is requested, which can only be done maximum one or two times per day (but they should not be necessary after an initial good setting was achieved, since the ROI will not change on its own after a manual setting). Only the last ROI image is saved and kept for a maximum of 1 year.

A daily pixelated background image for Telraam V1

The background image is a pixelated image that Telraam V1 users can check daily on their dashboard if they have one of the two latest versions of the Telraam V1 software (v10 or v11).

Since July 2020 (release of v10 software), the software allows you to check the camera image daily on your own dashboard, after logging in to www.telraam.net. To do so, select the "camera images" tab on the left side of your Telraam dashboard. 

In August 2021, version v11 of the software was released and several improvements were made to the system. If you wish to update your Telraam software, simply follow the instructions in the following article:"Updating the Telraam v1 software by yourself ".

Is your Telraam camera a security camera for this reason? 

No, it is not! Telraam makes it impossible to actively monitor or identify people or objects on these images:

➡️    Telraam V1 takes a background image by averaging images (or to be more precise, by taking a median value) over a period of 30 seconds, moving objects are therefore not visible. Images are taken only once a day by Telraam V1, and typically once or twice per installation of a Telraam S2 device.

➡️    The devices convert their images to a (very) low resolution, by "pixelization", and only these low-resolution images are transferred to the Telraam server. The resolution is high enough to be able to estimate if the camera position is good, but the resolution is so low that people and objects are not recognizable or identifiable. Since Telraam S2 does not apply averaging, the resolution is even lower in this case. 

Only you and the Telraam administrators have access to these images. As a consequence of low frequency, low resolution, and limited access, the privacy of passers-by is preserved and you can always easily check if your camera is still pointing where it should.
