How to send HTTP request to VRM to provide the list with trackId(s) and how to read the response?

Using RCP command 0xD007, you can retrieve the list of Track IDs from a Bosch VRM via a simple HTTP request. Although the response is wrapped in XML, the actual content is binary data that must be decoded according to the Bosch RCP specification.

Understanding the block structure and encoding rules allows you to reliably extract Track IDs, camera names, and related metadata for further integration or troubleshooting tasks.

How to read it.

There are 4 Blocks in this response.

Block 1:

Length - 00 80 => 80 bytes
Track id - 00 a0 (hex) => track id is 160 (decimal) (see Hex to Decimal Converter)
Ip 13 32 10 ac => 19.50.16.172 Please note the network byte order of IP address here
00 => Flags
01 =>Line => this is the video input 1 (coax) of a multichannel encoder. (= always 1 in case of a camera)
