How to adjust snapshot timing - Lorex NR8081

I recently purchased a Lorex HDIP86W system with six 1080p cameras.

The system is up and running as planned. However, I'd like to adjust the timing that is used to email me a snapshot after motion is activated.

Right now it appears the snapshot sent to me is about 5 seconds after the motion is triggered. What I need is for the snapshot sent to be about 2 seconds after triggered. Does anyone know how to adjust this?

Also, is anyone familiar with a Lorex specific forum? I'm kinda surprised a well-known company like Lorex doesn't have a dedicated forum to their products.
