Make npc_combine_camera Take Pictures (Hostile)

How do I make npc_combine_camera fully hostile towards a player, with a red flashing light and doing the “taking pictures” animation? It always does that in Half-Life 2.
I’ve set the relationship with a player to D_HT 99 but all it does is turn orange and focus on the player… how do I make it turn red and “take pictures?”

Ifyou have the sourcesdk_content folder theres a sample map of the train station with them in , heres a pic of there settings

I bet he wants to do it with Lua, not on hammer.
