IP Webcam manual bulk file download

Open http://192.168.1.10:8080/videomgr.html#/modet in Firefox

F12 → Console


Add Set to remove duplicates:

[...new Set(

  [...document.querySelectorAll("a[href*='/v/modet/']")].map(a => a.href)

)].join("\n")

Explanation:

querySelectorAll → all <a>

map(a => a.href) → array of hrefs

new Set(...) → keeps only unique values

[...new Set(...)] → back to array for join("\n")


Copy output → save as list.txt

mkdir ipcam10

nano list.txt → Ctrl + Shift + V

mv list.txt ipcam10

wget -i list.txt --base=http://192.168.1.10:8080/v/modet/
