dzVents Script for Dahua IP Cameras (Switch day/night profile)

Post by BakSeeDaa » Thursday 26 October 2017 9:15

Inspired by a post on IP Cam Talk made by @nayr, I made a dzvents script that takes care of that task. The script adds temperature and humidity to the camera OSD. I also added the ability to enable and disable privacy masks. Tested on Dahua IPC-HDW4231EM-AS and IPC-HDW5231R-Z

Prerequisites: dzVents version 2.3.1 or higher.

Documentation is the code. Some notes though ...

You should create a virtual switch device to control the privacy masks.

Each camera is defined in the webCams table. Each entry has a ['switchProfiles'] key. It can be a boolean or a function.
['switchProfiles'] = true The camera will switch profiles according to the timer triggers defined in TIME_SWITCH_DAY_PROFILE and TIME_SWITCH_NIGHT_PROFILE

['switchProfiles'] = false Profile switching will not occur.

['switchProfiles'] = function Define a function that either returns "day" or "night". Make sure to also add devices you use in your function as dzVents device triggers (if needed). (Named LightingMood in the example code below)

This script will need some customization and changes to work on your system. It's not intended to work "as is" for everyone. If you like it, copy it and make it yours. Don't try this script unless you are quite familiar with Lua scripting and dzvents. If You have IP camera related questions you should ask them on IP Cam Talk.
