如何使用Curl启用禁用运动检测DCS-933L（D-link Cam）？

Question

我在php中尝试此代码，但我没有解决！

$s = $motion = 1;
$camIp = "192.168.1.124";
$camUser = "admin";
$camPass = "gatelliHome";

$params = "ReplySuccessPage=motion.htm&ReplyErrorPage=motion.htm&MotionDetectionEnable=$motion&MotionDetectionSensitivity=85&ConfigSystemMotion=Save";

curl_setopt($ch, CURLOPT_URL, "http://$camIp/motion.cgi");
curl_setopt($ch, CURLOPT_USERPWD, "$camUser:$camPass");
curl_setopt($ch, CURLOPT_POSTFIELDS, $params);

curl_exec($ch);

curl_close($ch);

我不确定$ url和$ params是否正确！

你能帮助我吗？
