Looks like I read this topic a bit late. Did my research and realised my existing Core2Duo thinkpad will not be enough to power up 6 Hikvision cameras. So bought another used 3rd gen i5 thinkpad ( 2.6 Ghz processor and it is dual core). But taken
Blue Iris minimum specs is a dual core 2.0 Pentium, I thought it will work fine. Reason was Laptop has battery backup and after you put POE over UPS, you have additional battery backup for 30 minutes at least.
Now, when I am testing, laptop is always on 80-90% CPU with continuous recording with trigger. motion detection takes a lot of CPU. Disabling motion detection, the CPU sits at 50-60 %.
Cameras are: DS-2CD2342WD-I . I changed the settings on camera:
1. Resolution down to 1920* 1080 p
2. FPS down to 12
Rest all standard.
On Blue IRIS:
1. continuous recording direct to disk.
2. hardware decoding to default
3. no date time stamp to reduce encoding by blue iris.
I wonder how come the Hikvision NVR with less processor power can support 8 or even 16 cameras where as a 3rd gen i5 laptop cant.
Any suggestions would be highly appreciated.
