Hello, my name is Hammad and I am a full stack developer and website designer with 4+ years of experience in the industry. I understand that you are looking for someone to develop a PHP web page that sends PTZ commands to Hikvision camera so that it can be controlled remotely over ONVIF protocol. I believe I am the best candidate for this project due to my strong knowledge of PHP and API integration, familiarity with Hikvision cameras and their PTZ commands, experience in developing functions to control PTZ cameras and understanding of camera presets.
I would be more than happy to take on this project for you. My team and I are highly skilled in web development, mobile app development, content writing and PHP development. We have the expertise needed to create a web page with 7 buttons that send PTZ commands to Hikvision camera, specifically CURL over HTTP or ONVIF protocol. This would be done testing on a live camera assessable on public IP address during the project's completion period.
