5 e-PTZ is not supported.

6 The SD8313E and SD8362E: If continuous pan and tilt set are used, the camera will move

up to the top, then slowly move toward the direction of the pan command. This is the

camera’s expected behavior.

7 Panoramic PTZ is not supported. For more information please refer to the Vivotek user

manual.

8 When the FE8172 is added to the NVR, if MJPEG is selected the camera is defaulted to

constant bit rate. To increase the image quality the users can change the Bit Rate to

Fixed Quality on the camera web client before adding to the NVR however this will mean

the user cannot stream the camera at the top two resolutions 1536x1536 and 1920x1920.

9 Due to a QuickTime limitation when quality is set to fixed this will cause low frame rates in

QuickTime and NVR, this does not affect Victor.

10 Video streaming is unstable at high resolution when light conditions are low. Vivotek

suggests setting bit rate control to CBR for more reliable streaming. However users need

to be aware that it may produce lower than desired frame rate. In NVR4.3, 4.4 the bit rate

control can only be adjusted through the camera's web interface.

11 Vivotek have confirmed Switching from Day mode to Night mode may cause frame drops

and video loss, depending on the light condition, complexity of the scene and the

resolution setting. Setting the bit rate control to CBR may reduce the video loss.

12 The SD8362 and FE8172 Models are slightly different from all other models:

• They have a particular setting called Field of View (FOV). Resolution list, default

resolution, and fps list vary with FOV setting. Once added into the NVR, FOV

should not be changed. Otherwise issues may occur. To change FOV, the

camera must be removed from the NVR first, then changed before re-added to

the NVR.

• These two models support bit rate for MJPEG, which is not supported by any

other models. NVR 4.3 does not support bit rate control.

13 For FE8171V, FE8172 and all other fisheye models, MPEG4 is not supported, but H264

and MJPEG are still supported. The NVR cannot play the MPEG4 streams from these

models because they have custom data embedded, which will cause the NVR to restart

the stream frequently.

14 Some models for example, camera model SD8362 will support FPS greater than 30.

However NVR will only support up to 30 FPS.

15 The Following camera models SD8313E, SD8323E, SD8312E, SD8322E, SD8311E,

SD8321E all use the same firmware and are regarded by the handler as SD83X3.

16 The Following camera models PZ8111, PZ8121, PZ8111W, PZ8121W all use the same

firmware and are regarded by the handler as PZ81X1.

17 The FD8235H and FD8335H do not support dual stream MPEG4.

18 Back light compensation is not supported.

19 Due to camera hardware limitation the frame rates may not reach the highest frame rate.

20 Due to a camera limitation audio on the VS8801 encoder will not work on all channels if

the encoder is connected to any other client other than victor for example VLC. The

maximum number of connections on the encoder is 16 streams which will allow for one

client to be connected to each video and audio stream. To connect all video and audio

streams firmware version V0201c or above should be used.

21 Vivotek IP8362- in some circumstances due to low frame rate, high bandwidth and

complexity of the scene user may experience Significant video freeze in Client Instant

Playback throughout long period of video during night/day mode transition. This should

not be observed when using Search and Retrieve.
