I bought 10 cameras c7824wip and one camera C7815WIP but when connected to the NVR have delay and jumps in the image.

Equipment installed:

1 C7815WIP
9 C7824WIP
1 router TL-WR941ND wifi (Radio distance camera 2 to 10 mt)
NVR dahua HCVR4116HS-S3

Issue:

- Jumping image
- Delay from 5 to 15 seconds.
- Sometimes the video is fast and other times very slow.

Tests:

Wired cameras: Continuing failure.
This change encoding: H.264 coding was tested and H.264B. failed.
Lower FPS: was tested from 1 to 25 FPS. failed.
This lower resolution: 720p was tested and 640 but no difference in image is observed.
Distance to cameras: Cameras have faults 2 m
Change NVR: NVR 4 channel was tested. Failed.
WIFI adjust parameters:
Firmware Update: 48.53.72.76 to 48.53.72.78. No visible changes.

Observations:

The model has much lower C7815WIP delay or hops that the C7824WIP model.
The router is dedicated to the service of the cameras and NVR.

As for the network, it was tested each of the chambers.

1) When you ping no packet loss. There is not much difference between the rate with UTP cable or WIFI. The fault is the same whether the camera is wired.

2) From the computer connected either wired the camera has a delay of 2-5 seconds.

3) From the NVR connected either wired the camera has a delay 3-15 seconds, even with one camera connected.

4) He tried another router and failure is the same.

5) Cameras connected to 2 mt have the same faults.

Please also tell me which is the ideal decoding?
The resolution of the cameras is VGA or 720p?
how i make advanced settings on the camera?

Thank you

Hello
I have same problem. I have 2 old cams and they work nice so I decided to buy two additional  cams C7824WIP by Amazon

The performance is horrible. It requires 30 seconds to connect. The old ones just 2 seconds. It updates the image once each 10 seconds with a delay of one minute so trying to rotate the camera is imposible. They are connected using wifi and I am using a android device in the same network.  It happens the same connecting remotely. I cannot believe there isn't a solution I and I cannot believe newer models work so bad. Does it exists a tweak? Maybe an incoming sw fix?  It's a shame because the old ones are nice. The new ones are unusable

Dear customer ,
Regarding this issue, I would suggest you to uninstall the app and re-install it,  reset the cam and reconfigure it, then upgrade the firmware of the cam to the latest one, and test again.
