I ordered from here and they just substituted what I ordered for a different camera without asking (same camera but with no mic)
I've got exactly the same issue. Have contacted their support today. We were meant to get the new model (I91BM) but they have provided I91BF which is the old model with no audio, fewer resolution options, lower SD card storage options (if you want to go that route) and no substream.
To say the least, I am not happy and will be chasing for a replacement or full refund. Frustrating when it appears they have purposely done this to clear old stock.
How did you get on?
They kept blaming the 'warehouse' when I contacted them, ended up with another $10 off. Was going to fight it more but ended up leaving it
loaded hikvision firmware onto the camera
Also I can confirm I have substream on my copy of firmware for this camera
Looks good. Some useful comments from an Amazon review:
"These cameras can be upgraded using Hikvision's own firmware, model DS-2CD2383G0-I, which you can find on Hikvision's website.
When you upgrade using the Hikvision firmware, you can then add the cameras to your 3rd party NVR (I use Synology) by brand and model, instead of using ONVIF. This gives you access to all the advanced detection features, H.265+, etc.
Here are a few recommendations for setting up your security cameras…
1) Setup all your surveillance equipment on a separate network or VLAN. Only allow related/established traffic, DHCP, and NTP, and only from your internal servers. Bock all other traffic from that VLAN to the internet and to your own network. This is just good security practice no matter the brand you use.
2) Update your firmware to the latest available and add your cameras to your NVR using the brand/model instead of ONVIF.
3) Use H.265+ compression, even if you lose some advanced detection features, unless you really need face recognition and have an NVR to handle that.
4) Always choose variable bitrate.
5) Set your resolution and video quality to the highest available for the main stream. For the sub-stream set the resolution to 640x360 for optimal mobile viewing, and the video quality to "higher".
6) Set your frame rate to 15 for the main stream and 8 for the sub-stream. On the high stream, you won't notice hardly any difference if you go higher than 15, unless you are monitoring a casino or something along those lines.
7) For the main stream, set the max bitrate to 4096, and average bitrate to 2048, as recommended by Hikvision's Calculator Tool (https://tools.hikvision.com/calculatorTool/index.html). The max bitrate is kind of irrelevant for the sub-stream, though you could set it to 512.
8) If your situation does not require continuous recording, consider only recording on motion detection at high quality with a 1 second buffer and 10 second minimum length. You will be able to store a lot more video, your hard drives will last a lot longer, and you won't necessarily need purple drives for your surveillance setup. Plain red (NAS) drives will do just fine, since you won't be constantly hammering the drives.
9) Record on all motion at lower sensitivity, but only issue alerts on smart (advanced) event detection. Be sure to define maximum/minimum target sizes for your Line Crossing and Intrusion Detection smart events. This will greatly lower your false positives."
