Hikvision isapi - email picture at set times

g6swj · Nov 15, 2024

Hello,

I am new here so forgive me if I have posted in the wrong place. I am using a DS-2CD2386G2-ISU/SL and an Arduino with an ethernet shield.

I can sucessfully update the OSD overlay text so have got to grips with using some aspects of the API.

Manually the only way I have found to email an iamge requries human intervention by toggling the "Enable Alarm Input Handling" enable/disable.

I have been able to control the "alarm type" NC or NO vi the API but cannot seem to set the "Enable Alarm Input Handling" enable/disable.

Any help will be gratefully received - or is there a better way to do this

I did not find the method of using the time schedule enable/disable worked for me

Code:

XML
big_string += "<?xml version=\"1.0\"encoding=\"UTF-8\"?>\n\r";
big_string += "<IOInputPort version=\"2.0\" xmlns=\"http://www.hikvision.com/ver20/XMLSchema\">\n\r";
big_string += "<id>1</id>\n\r";
big_string += "<enabled>true</enabled>\n\r";
big_string += "<triggering>high</triggering>\n\r";
big_string += "</IOInputPort>\n\r";

Regards
Jonathan

What you are doing is manual alarm input, which have high and low values,so after sending a "high" trigger value, send "low" to close value, the delay you can add minimum of 1s

I haven't seen manual email send node in entire documentation. Email is an action to an event trigger. So you either trigger an event or alarm input to actually start email send

Other way around for your aplication scenario.

In your application set:
/capture controller- This will be called from either phone, windows, mac, 3rd party whatsoever.
Capture request toward cameras after /capture has been ccalled - http://IP

This may be of use to someone - still work in progress but this Arduino code does the basics

Code:

IPAddress myDns(1, 1, 1, 1); /Random, not sure if I need to do anything specific here

IPAddress gateway(192, 168, 1, 1); /Random, not sure if I need to do anything specific here

  }

Bit hard on Arduino - my coding a little slopppy

IPAddress subnet(255, 255, 255, 255);
