I have an NVR with 4 cameras and it has worked well for a few years, I have always wanted to get BI up and running so I installed the demo and WHOOAA I am running at around 14% when using the admin interface.

Like many others, I fell into this arena with plenty of tech knowledge, but little nouse about cameras, the NVR just works, but BI lets me play….. and the more I play the more I am learning, the more I am reading and the more I am testing. Many other have commented about how complex BI appears on first contact, but when you start to ‘USE’ it, you realize it is that complexity that makes it the product you needed in the first place.

Using BI v5 for 5 cameras of mixed types – Univision, Reolink, and Boa – with a mix of resolutions (4MP, 5MP) and differing levels of PTZ capability. All cameras are ONVIF compliant. Everything just ‘worked’ and has no problems with detecting hardware. Although all cameras have in-camera motion detection, I prefer the BI software based motion detection/ It seems top have less false positives. Happy with it so far. Cameras are recording between 15 and 25Hz. CPU usage is only about 15% on an older i7-3770. The web interface is nice and allows me to use the machine running BI without a monitor for most tasks.

Awesome impressive. I got up and running in minutes but there are many features and options I still need to understand. Little else to add.

Great software! Highly configurable and in my (albeit short) experience, very reliable. Direct-to-disc recording and no overlays will minimize processor usage. UI3 web interface is quite good and easy to use on a mobile device. Blue Iris motion sensing is easy to use and more accurate than my camera’s built-in alerts. It’s worked with every camera I’ve tried, including those with microphones. For my small handful of cameras at home, Blue Iris beat all the competitors in both value and performance. Finally, there is a huge amount of information available online about configuring Blue Iris, and the built-in help is excellent to boot.
