Automatic SCENE change

[lane777smith]

I have two 2387's and i was wondering if anyone has figured out a way to automatically make the SCENE's change based on sunrise/sunset, or even by using a light meter of some sort. Similar to the Dahua Sunrise/Sunset program that's out there.

Firmwares actually contain getLux function (saw using RCE and shell access to G2) but i havent seen anywhere on ISAPI or SDK documentation that we can use it as integrators. I believe its purely internal command for IR trigger.

Thanks for the input.. utilizing an internal "lux" meteor would be the ideal solution for sure!

Afterall you do have "RCE exploitable model" it just depends if you are actually on exploitable firmware, if you are you are good to go with python script

GitHub - Aiminsun/CVE-2021-36260: command injection vulnerability in the web server of some Hikvision product. Due to the insufficient input validation, attacker can exploit the vulnerability to launch a command injection attack by sending some messages with malicious commands.

This gains you access, edit a script to your desire to automate it

But you have colorVu model which have white led which do have ability to automate with ISAPI requests

I'm looking to do something similar. I need a command to switch the camera to Night and another command to switch the camera to Day. The Auto Day/Night setting means the Gain setting is forced to 100 and not adjustable and being able to set this up would get around that.

It looks as though it should be possible using /ISAPI/Image/channels/1/ISPMode/ but I can't fathom it out how to send the command (I'm pretty clueless with anything involving code). Can anyone provide a simple example that might help? It looks as though I need to specify the IP and path and then enter some xml. I have everything in place to trigger it to switch from a lux sensor connected to my Hubitat C8 hub but I'm stuck with the precise format of the url (do I have to include adminassword@) and the xml or json to send. Any help appreciated

EDIT: Switching manually between Day and Night allows the gain to be adjusted but the setting is common to both. What I actually need is the command to switch to a specific 'scene', as Day/Night, Gain, Shutter speed etc are saved individually. I want to be able to send a command to change the scene to 'Normal' which will equate to my daytime settings and 'Low Illumination' which will be for my night setup

OK I've surprised myself and managed to get this working.

To switch scenes it's http://IP_Address:http_port/ISAPI/Image/channels/1/mountingScenario In my case the camera is connected to the PoE port of an NVR and with virtual host activated I can specify 65006 for cam 6

I've set up 'Normal' and 'Low Illumination' as desired. The camera is one of the new hybrid light ColorVu models so my 'Low Illumination' setting has the supplement light mode set to 'Smart' in order to bring on the white LED and switch back to colour on event activation.

The xml to send in the body is:

<?xml version="1.0" encoding="UTF-8"?>
<MountingScenario version="2.0" xmlns="

http://www.hikvision.com/ver20/XMLSchema

">
<mode>lowIllumination</mode>
</MountingScenario>

alter <mode> to suit

Well use postman, any settings you can do on website you can clone the request from inspect element looking at network tab

Yes I've got the scene switching back and forth using postman and now have to figure out how to implement that in node-red.

When I'm sending using postman, I can see (using Proxyman) that initially the camera sends a 401 connection refused, then postman is resubmitting using this setting:

"By default, Postman will extract values from the received response, add it to the request, and retry it. Do you want to disable this?"

So if I disable that it doesn't work. I'm not sure how I can resolve that as it will not authenticate when sent from elsewhere

node-red i googled a bit and it sounds mind blowing when it comes to simple tasks

Yeah I already had node-red set up to link my alarm system zones to my Hubitat hub using MQTT. Last night after a long time messing I found the 'Hikvision Ultimate' palette and added that to node-red. That has an xml node and once you've configured the authentication you can just paste the xml snippet in directly, so I've got that up and running and will link it to an existing external luminance detector in Hubitat. I've also had a play with the 'text overlay' node - I've linked that up to various devices in Hubitat and have added a temperature display and house alarm status display to one of my cameras. Now I can see at a glance the status of my alarm and the temperature in Hik-Connect (rather than having to open a different app for the alarm).
