Reverse Engineering of Hikam S6 (HI3518 E)

Why?

I wanted to integrate the camera into my home security system. The only problem is that I want to toggle the alarm of the camera based on the security system status. Currently, this is only available via the app or a time trigger which is booth not sufficient for me. So the main target was to change the alarm status without the app.

What I've done so far:

My first try was to capture the TCP packages between the Android app and the camera. Soon I realized that they are only TCP+SSL (not pinned) requests to a cloud service of Hikam. So I installed an emulator with the Hikam app and Wireshark. I've seen some packages but the payload is very strange and even if I send the UDP commands again the status won't change. So this was a dead end for me.

An index for a MySQL CLOB column cannot be created with Liquibase createIndex at the moment, 
since MySQL requires a length limit for this index, see http://dev.mysql.com/doc/refman/5.5/en/create-index.html

As a workaround, you can use the modifySql to 'fix' the sql generated like so:
<createIndex tableName="foo" indexName="i_foo">
    <column name="myClobColumn"/>
</createIndex>
<modifySql dbms="mysql">
    <replace replace="myClobColumn" with="myClobColumn(80)"/>
</modifySql>
