使用 Tkinter 按钮 (Python) 控制 IP 相机

Question

I have been trying to create a GUI with tkinter to control 4 IP cameras with Python. At first I thought it's because I didn't have the right IP or Ports but I used packet sender to check it out. I'm confused on why the program won't work when I try to use it in Python 2.7. Below is the code for one of my cameras - left camera, it is a PTZoptics camera. The camera and the computers are all connected on one network via ethernet. Currently, I am currently controlling them with an IP joystick.

import socket
import tkinter as tk


class Example(tk.Frame):
    def __init__(self, *args, **kwargs):
        tk.Frame.__init__(self, *args, **kwargs)
        self.up = tk.Button(self, text="LEFT CAMERA UP")

        self.down = tk.Button(self, text="LEFT CAMERA DOWN")

        self.left = tk.Button(self, text="LEFT CAMERA LEFT")

        self.right = tk.Button(self, text="LEFT CAMERA RIGHT")

        self.up.pack(side="top")

        self.down.pack(side="bottom")

        self.left.pack(side="left")

        self.right.pack(side="right")

        self.up.bind("<ButtonPress>", self.on_LCup)
        self.up.bind("<ButtonRelease>", self.on_LCrelease)

        self.down.bind("<ButtonPress>", self.on_LCdown)
        self.down.bind("<ButtonRelease>", self.on_LCrelease)

        self.left.bind("<ButtonPress>", self.on_LCleft)
        self.left.bind("<ButtonRelease>", self.on_LCrelease)

        self.right.bind("<ButtonPress>", self.on_LCright)
        self.right.bind("<ButtonRelease>", self.on_LCrelease)

    def on_LCup(self, event):
        LeftHost = '10.30.1.41'
        port1 = 5678

        LC = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        LC.connect((LeftHost, port1))
        LC.send("81 01 06 01 08 08 03 01 FF")

    def on_LCdown(self, event):
        LeftHost = '10.30.1.41'
        port1 = 5678

        LC = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        LC.connect((LeftHost, port1))
        LC.send("81 01 06 01 08 08 03 02 FF")


    def on_LCleft(self, event):
        LeftHost = '10.30.1.41'
        port1 = 5678

        LC = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        LC.connect((LeftHost, port1))
        LC.send("81 01 06 01 08 08 01 03 FF")

    def on_LCright(self, event):
        LeftHost = '10.30.1.41'
        port1 = 5678

        LC = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        LC.connect((LeftHost, port1))
        LC.send("81 01 06 01 08 08 02 03 FF")

    def on_LCrelease(self, event):
        LeftHost = '10.30.1.41'
        port1 = 5678

        LC = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        LC.connect((LeftHost, port1))
        LC.send("81 01 06 01 08 08 03 03 FF")


if __name__ == "__main__":
    root = tk.Tk()
    Example(root).pack(side="top", fill="both", expand=True)
    root.mainloop()

Answer 1

add --> bytes.fromhex in LC.send:: LC.send(bytes.fromhex("81 01 06 01 08 08 03 03 FF"))
