IR LED intensity according zoom on AXIS Q1715

[minicat280]

finally i can create event to turn on IR LED by using following CGI command and create the event when i turn on night mode.
http://192.168.0.138/axis-cgi/com/serial.cgi?write=FF01E0010002E4 - IR LED ON
http://192.168.0.138/axis-cgi/com/serial.cgi?write=FF01E0010003E5 - IR LED OFF

but my question is isn't possible to do IR LED intensity according zoom level, it means if i zoom very far, the IR LED intensity become strong and if i zoom very near, IR LED intensity become weak.
since event no option for the condition, isn't any other way to do this?
please advise, thanks.

Answers to your questions will most often come from the community, from developers like yourself.

Hi @minicat280 ,
You can read more here on OptimizedIR. I don't think AXIS Q1715 is supported.

You can also try the Set individual intensity APIs:

@vivekatoffice this is what i get

Hi @minicat280 ,
I am not sure on "stty -F /dev/ttyPCC0 9600 cs8 -cstopb" this line for your setup 😢 . Let me ask someone who can help in this topic.

Do try out this Reference to understand more.

Hi @minicat280 ,
I have build the following code for you:
build_read_data_from_a_serial_port.zip

#include <stdio.h>
#include <stdlib.h>
#include <fcntl.h>
#include <unistd.h>
#include <errno.h>
#include <string.h>
#include <termios.h>

#define SERIAL_PORT "/dev/ttyPCC0" // Change this to match your serial port
#define BAUD_RATE B9600 // Change this to match your baud rate

int main() {
    int serial_port;
    struct termios tty;
    char buf[256];

    // Open serial port
    serial_port = open(SERIAL_PORT, O_RDWR);
    if (serial_port < 0) {
        perror("Error opening serial port");
        return 1;
    }

    // Set serial port options
    memset(&tty, 0, sizeof(tty));
    if (tcgetattr(serial_port, &tty) != 0) {
        perror("Error getting serial port attributes");
        close(serial_port);
        return 1;
    }

    cfsetospeed(&tty, BAUD_RATE);
    cfsetispeed(&tty, BAUD_RATE);

    tty.c_cflag &= ~PARENB; // Disable parity
    tty.c_cflag &= ~CSTOPB; // One stop bit
    tty.c_cflag &= ~CSIZE; // Clear data size bits
    tty.c_cflag |= CS8; // Set 8 data bits
    tty.c_cflag &= ~CRTSCTS; // Disable RTS/CTS hardware flow control

    // Apply settings
    if (tcsetattr(serial_port, TCSANOW, &tty) != 0) {
        perror("Error setting serial port attributes");
        close(serial_port);
        return 1;
    }

    // Read data from serial port in a loop
    while (1) {
        ssize_t num_bytes = read(serial_port, &buf, sizeof(buf));
        if (num_bytes < 0) {
            perror("Error reading from serial port");
            close(serial_port);
            return 1;
        } else if (num_bytes > 0) {
            printf("Received %zd bytes: %.*s\n", num_bytes, (int)num_bytes, buf);
            // Add any processing logic here
            // For example, you can parse the received data
            // and perform further actions based on it
        }
    }

    close(serial_port);
    return 0;
}

Install the ACAP(*.eap) and run the application using SSH:

Please share the screenshot.

hi, @vivekatoffice ,
i can install ACAP and run the application. but it's look like no message received. i have try ptz and turn on IR, but receive nothing.

[vivekatoffice]

Thanks @minicat280 for the snapshot. I need to troubleshoot more on this.

[vivekatoffice]

@vivekatoffice really appreacited your reply. but may i know how to write those command into one file and upload to the camera?

Which programming language you use in your application for "http://192.168.0.138/axis-cgi/com/serial.cgi?write=FF01E0010002E4" or just created the custom controls?

[minicat280]

@vivekatoffice when i sent the read command, PTZ function no working, after timeout then just can PTZ.
zoom is ok, but nothing data read, so i not sure how AXIS camera communication protocol.
http://192.168.0.138/axis-cgi/com/ptz.cgi?zoom=500
if i sent this command, the zoom function is working to 2x.

[vivekatoffice]

if read=8 then?

[minicat280]

same, read=8 nothing data show. so can i assume that zoom protocol transfer by RJ45 or other way?

[vivekatoffice]

Ya look like the same to me.

Checkout this product:
Only support Pan and Tilt 😄

You may need to use the write=HEX VALUES from PTZ OEM to check if it works.
