I'm having a strange issue with motion detection and recording. Being fairly new to BI4, I'm guessing that I haven't yet discovered a setting that will resolve this.

I've reviewed the FAQs and other posts, but haven't found anything similar. The core of the problem is that objects that trigger recordings seem to 'teleport' through the scene. Our cat will wander onto the patio and trigger the recording. We'll watch him walk smoothly for about 4-5 feet, then suddenly, either he freezes or (more commonly) disappears for 2-3 seconds, only to reappear at the other end of the patio, again with fluid motion in the video. It's as if the camera stops sending frames but BI keeps recording. I have 3 cameras and all 3 are exhibiting the same effect. My concern is that I will miss some critical event due to this.
Environment: Cam1 - older VGA (640x480) IP camera Cam2 - Foscam FI9928P 2M Cam3 - Foscam FI9828P 1.3M Switch - Cisco 4506, 1GB POE+ ports, cameras are on the Workstation VLAN currently, but will move to a dedicated Camera VLAN when the new cameras are added. Cabling is all CAT-5 or 5e. BI4 Host 1 - Physical system - AMD 8 core 4 GHz, 32G RAM, 500G allocated to BI on separate drive; Windows 10, latest update and fully patched. BI4 Host 2 - Virtual system - Intel 4 core 3 GHz, 8G RAM, 250G allocated to BI on separate drive; Server 2016, latest update and fully patched.
The hypervisor is a Dell 710R, 12 core, 144G RAM, with 24T SAS storage. It has a 2-port etherchannel trunk to the Cisco switch. I set up Host 1 initially to evaluate and test BI4. Both hosts have BI installed in service mode. I disabled the service on Host 1 and manually configured Host 2, just to see if the problem was with my initial configuration settings. The only difference in BI settings between the two hosts is that Host 1 used IP addresses to define the cameras while Host 2 uses DNS hostnames, and Host 2 still has the defaults in the motion triggering settings.

Since all cameras and both hosts exhibit this issue, I have to assume a configuration setting change is needed, either in the cameras or BI4, but I'm just not sure what to check. I use Milestone at my office with a similar network and virtualization configuration and don't see anything like this. Any help is greatly appreciated! Just a few ideas, have the frames 15 FPS & the frame interval set to 15 on the camera set also to adjust bit rate to 2048 then try 720x1280 for all cameras or less prior to 1080P setting. Use the Direct to Disk option, 'pre trigger setting' to 1 second.
Trigger variance options, time of motion try 1 second, then try 170 & 25 in that area for sensitivity & no more then 1MB network buffer setting. Then you can tweak further after you get all cameras toned down a bit, then move up until you notice the lag again. I had similar issues and it was the fine tuning, managing CPU load. Also after you make changes to cameras direct interface one still has to go into BI interface, open camera properties & select 'ok' after changes are made to ensure changes are reflected. I find that for myself that going low with resolution & FPS to start then gradually increasing is really what it takes to tweak it. Thanks for the ideas!
I moved the cameras to a separate VLAN yesterday and added a V-NIC to the BI4 server so it's directly connected to the camera VLAN. I did a bit of performance tuning on the cameras as you suggested, starting with 15 fps and 30 for the keyframe, and then enabling VBR and a 1K bit rate. I have 3 more cameras to permanently mount this weekend, so will have an opportunity to investigate further.

I don't think CPU is an issue, as I pointed out in the virtualization post, my BI4 server is sitting there at 8% load in the guest, and 0-1% on the hypervisor host. It spikes to 20% when recording starts, but then quickly settles back down.
