and particularly highly reflective objects will fool the auto exposure and auto flash systems as they try to achieve a good "average" exposure over the whole scene. The light source is part of the camera, so if the exposure system is set to automatic, and averaging, objects in the foreground. This is no different than getting good exposure with a camera that has a built-in flash or a flash mounted on the hot shoe. When you switch off the illuminators, the brightness of the wall drops, and the auto exposure in the camera readjusts to give a better exposure over the scene. So as fenderman says, you need to adjust the camera angle so that it cannot see the wall. So the camera is doing exactly what it is supposed to do, and turning down the LEDs and the exposure to get a nice "average" brightness over the whole scene. your setup, the IR illuminators are lighting the light colored wall, and its image dominates the picture. The problem with any auto exposure system, and with auto adjustment of IR illuminators, is that the exposure (and intensity of the IR, in cameras that do adjust that - which these cameras do), is set to achieve an average brightness in the scene, that is, well, average. This is where you will upgrade firmware in the futureįind out your current firmware version here I generally pick times I know I'm at the house. Some including myself set the camera to "auto reboot" once a week. The DST setting are now really nice and you can set the 2nd sun in march and 1st sunday in november to match correctly. To put this on your video feed, head back to CAMERA/VIDEO and then the "Overlay" tab. (BlueIris doesn't store the overlay when using direct to disc, which you should) Highly suggest under this item going to "date/time" and setting a NTP server to sync the time on the camera.īetter to display the time right from the camera with an overlay than in BlueIris. If you use BlueIris you probably won't need this unless you also trigger to SD or network storage This is where you set IN CAMERA event detection from motion to alarms. In my setup, I turn everything off as the camera only talks to Blue Iris. (THESE CAN BE CHANGED LATER BUT THIS IS A GOOD STARTING POINT) Some down and dirty settings here to get you started with a 2MP dahua Now click on the "VIDEO" menu item under conditions on the left I don't know which 2231 you got but if it's a zoom then there is a tab under Conditions called "Zoom and Focus" this is where you will adjust your zoom and focus(duh) But make note this is where you change exposure settings. Being brand new I honestly wouldn't change anything here YET. You should be defaulted to the CAMERA/CONDITIONS menu item on the left Be sure to do that before you leave the page.Īfter clicking that you will see a menu to the left and some tabs in the current view. *You must hit save at the bottom of the pages or your settings won't stick. (these are just suggested starting point) Here are some basics to get you started in setting up your cameras for BLUEIRIS (if you are having problems seeing the video image in the web browser, go here) On that note, not sure if someone has done a basic "Dahua" camera setup for BI.Īfter you have set the IP you want to log in to the camera via the web, Click to expand.Yes this, but pretty sure he meant he uses a web browser to log into the cameras to set the config.
