XEOMA DISEASE UPDATE
These options detect when there’s no update of the camera image and no audio from the camera.
Trigger if there are problems – if there is at least one problem being detected from the selected ones, then the module will pass the signal to the following modules in the modules chain
it is passing signal to the following modules in the modules chain Trigger always – the module is always in the “Triggered” mode, i.e.
Trigger if there are no problems – if there are no problems being detected from the selected ones, then the module will pass the signal to the following modules in the modules chain In the “Problems detector” you will find the following options: Whenever you click on the module, you’ll be able to enter its module’s settings. Let’s take a closer look at the module’s settings. Several types of notifications can be connected to the same camera. For example, you could send a notification to the system administrator when signal from one camera is lost but when it’s another camera – guarding the safe – trigger an alarm at once. Video analytics behind this sabotage detector provide automatic notifications of the form of choice about the scene changes (when camera is being tampered with) or when system’s “health” is involved.Įnhanced video analytics, flexible configuration and modular structure help you set up the system to give notifications for certain cameras when you want them. To provide unsupervised system health monitoring Xeoma offers not just edge-cutting on-screen diagnostics but also the “Problems Detector” module. If there are many cameras to monitor, operators may miss this little change and, consequently, miss the criminal act that was going on right under their nose, just like in a classic spy movie. Technically, cameras are fine – they are monitoring a site all right, but not the site they should. The only damage here is what the criminals will take from the guarded site while the cameras are not watching. Camera itself is not vandalized which is a plus, but on the other hand, the last received frame of such “frozen” cameras would hang on the display like it’s all good for a long time, without giving away that the cams have been tampered with, allowing wrongdoers operate from the comfort of a blind spot and then leave the scene unnoticed with their loot.īest case, from the point of view of video surveillance system’s owners, would be if the camera is turned – simply pointed in another direction, blinded with a flash of light (for example, with car’ headlights) or obscured, for example, with a piece of cloth or a bag. However, this is not the case for VSS that run for years and years without human supervision: not only is equipment damaged, valuables stolen, without any evidence of who did it, but also videos of other episodes can go missing before it is detected that the system isn’t working.Īnother scenario includes more tech-savvy criminals who cut the cords for the cameras, for example, Ethernet wire where the camera stops sending its stream and the image freezes.
XEOMA DISEASE PLUS
This might not be the cheapest scenario for video surveillance system’s owners, but on the plus side, operators will detect that camera was disabled that very instant, and take urgent measures. Vandalizing or breaking the cameras is the most frequent offenders’ choice. Criminals try their best not to be filmed (that’s why it’s essential to project their placement right in the first place) and, if that’s hard, tend to eliminate the threat. That’s when automated video analytics of the so-called sabotage detectors come in especially handy – notifying operators and administrators about the threat or a criminal act in progress.įirst victims of vandalizing are usually cameras themselves. In such conditions it’s hard to keep tabs on whether all cameras are always online, or if the video surveillance system is functioning well. Large-scale video surveillance systems, ones of corporate level, utilize hundreds, even thousands of cameras. ← Back to Articles Problems detector in Xeoma
