Hi everyone - hope you are all well. I am having a problem with my 3 CCTV cameras. They are Hikvision POE IP (100mbps) cameras. I have them connected to a 1Gbps network and recording to a Netgear ReadyNAS 1Gbps NAS. The issue I have is if I turn the bitrate on any of the cameras up past 4mbps, I get horrible stuttering, moreso in recordings. I run them at 25fps and 1080p. I can't understand this problem as there is plenty of bandwidth available. For example - 4mbps is fine on live view however recording have a slight stutter. Anything past 4mbps affects both live and recorded views. The only other traffic on the network is internet traffic to various computers, phones, tablets etc. My net connection is 80mbps. Thanks and appreciate any help/advice. Trevor

I don't believe its a camera fault - I am relatively new to CCTV so am still on a steep learning curve. My network runs on Cat5e cabling and Gigabit switches. The Netgear ReadyNAS has 2x 2TB WD Red drives in on RAID 0 and is also Gigabit. The Hikvision cameras are 100mb, not gigabit. I very highly doubt it is a network issue. Baring in mind I am after as much quality as possible, I have the video quality cranked right up to maximum and maximum frame rate the cameras will allow. I just assumed that even a 8mbps bitrate stream would be childs play on a gigabit network with nothing other than 80mbps internet traffic maximum. Or is bitrate measured differently to network bandwidth? Thanks.

Hello... I have an Avigilon set up with an NVR running the ACC services which then goes into a 4G router (no ADSL on site). I have the control center client running on a PC at my own location via ADSL. I then plan to set up a VPN between the remote location and my location however in testing the idle data use alone is quite high (approximately 3GB per month). I have setup an alarm to trigger the live viewing when movement is detected which is working perfectly however it would be useful if this could also trigger the VPN to go up and then disconnect when the alarm is acknowledged. I so far have not been able to get this to work (using IPSec). Is this possible or is there constant traffic between the control client and the server preventing this? I do have a good understanding of networks however I have limited experience with VPNS. Appreciate the help. Thanks

Sorry for the long delay! I have dropped to 3mbs on the bitrate and so far all is good. I am using a netgear readynas with 2x WD Red drives in RAID0. Thank you for the replies - going to try get the bitrate down further based on your advice.
