An updated version of the camscan.py script to search Shodan for webcams. This script uses the new Shodan API documented at https://developer.shodan.io as well as the new search_cursor() method to easily iterate over results.

camscan.py

# Configuration options
API_KEY = 'YOUR API KEY'
SEARCH_QUERY = 'netcam'
CONNECTION_TIMEOUT = 1.5

def is_camera(ip_str):
	"""Check whether the given IP operates a valid webcam by checking for the existence of a URL."""
	try:
		# Connect to the camera
		sock = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
		sock.settimeout(CONNECTION_TIMEOUT)
		sock.connect((ip_str,80))
		sock.send('GET /anony/mjpg.cgi HTTP/1.0\r\n\r\n')
		res = sock.recv(100)
		if(res.find('200 OK') > 0):
			return True
		return False
	except:
		return False
