About

Dallmeier SeMSy Mobile Client

Features
Read full description

SeMSy® Mobile Client enables mobile and professional access to Dallmeier camera and recording systems via the Dallmeier Connect Service. After creating an account, the latest Dallmeier cameras can be integrated directly, quickly and easily via a QR code and assigned to a location (site). Current Dallmeier recording systems can be optionally integrated just as easily, which also support access to older camera generations as a link (proxy). User management & Sharing The integrated user management of the SeMSy® Mobile Client allows to invite other users directly from the application to access the cameras and recordings of a site. The rights of the individual guests can be individually defined via user roles and, if necessary, revoked again. Connection & Security Live access to the video streams is encrypted end-to-end via the Dallmeier Connect Service. Using state-of-the-art technologies saves the time-consuming configuration of firewalls and routers in the local network and ensures maximum system security by avoiding direct connections between the devices involved. The same applies to the playback of the locally stored recordings, which are neither edited nor buffered during the entire transport route to ensure the highest data security. Overview & Information The cameras of a site are displayed in an overview with refreshable and scalable preview images. After a refresh, this view allows for quick and intuitive information about the overall situation of a site. The individual cameras can be selected for playback mode by tapping on them or switched to display live video directly in the overview by doing a longpress on the thumbnail. Playback & Control After selecting a camera in the overview, it is first displayed with a live image that already supports pinch-to-zoom. The interactive and scalable timeline can be used for initial positioning in the recording by swiping, and allows direct selection of an event by tapping the displayed icons. For convenient playback control with only one hand, the multifunctional track wheel is available, whose step width can be adjusted as well as the playback speed. Event messages & Push The status and event messages of the connected cameras and recording systems are transmitted via the Connect Push Service to the Mobile Client, which displays all messages in a clear list and, if necessary, with a preview image of the triggering event. Playback of the event can be activated directly from the message list, which is then clearly displayed in the timeline together with other messages. Further Features: - Quick activation of the video display - Easy switching of video quality - Display of the overview module of Panomera® systems - Dewarped display of the latest Dallmeier fisheye cameras - Overview with presets for multiple cameras of a site - Intercom function, if supported by the camera - Control of lighting and relays , if supported by the camera - Operation in the background with push messages as toast notification Included Dallmeier Connect Services: - SeMSy® Connect Access Service - SeMSy® Connect Streaming Service - SeMSy® Connect Push Service - SeMSy® Connect Event Service Supported Dallmeier systems: - Dallmeier cameras with DOMERA® OS as of 14.2.x - Dallmeier recording systems with SeMSy® Recording Server as of 10.x.5 - Dallmeier recording systems with SMAVIA Recording Server as of 9.x.14 - Further Dallmeier and 3rd party cameras supported via recorder as proxy
