Note:
Why can't get image from H.264 IP Cameras? But can access MJPEG IP camera
images with the same broadband WAN/ Internet connection?
IP Cameras with H.264 compression won't display video if I frame lost, received P/B
frames won't display without I frame, at bad network connection, packets may lost or
out of sequence, video won't start until a full I frame arrived.
Note:
I frame: full image
P frame: moving objects of I frame
P frame must join to I frame to become a full frame, if I frame lost, no video will display.
Please also check the available "upload bandwidth" , normally ADSL is very small
around 256~384kbps, please adjust the video settings to WAN defaults, adjust the bit
rate to 256kbps, adjust video resolution to 640 x 352 or 800 x 600 to fit for lower
"upload bandwidth".
Note: the lower "upload bandwidth", the worse "network connection" the lower
resolution should choose.
Please always use smaller "I interval" for Internet accesses, the worse network
connection, the smaller "I interval" should use.
If set >2,048Kbps throughput with highest resolution (>800 x 600) and full frame rate
(30fps) on an ADSL connection with poor bandwidth, no video will display.
Please select most reliable MJPEG video compression, which sends pictures frame by
frame, will drop pictures automatically at small bandwidth, which means users will
always see pictures changing, the refresh rate is according to bandwidth available.
The parameters of video quality and frame rate are not adjustable, will automatically
adapt the available bandwidth.
This IP Camera adopts most advanced H.264 Main Profile compression with Dual
compression (h.264 & MJPEG) & Dual video streams output, which means you can
choose most suitable compression/ resolution/ frame rate/ quality according to real
application scenario.
Note:
don’t use the advanced image setting if you are not professional personnel.
