I'm reaching out regarding the surveillance ball, as I'm quite interested in its specifications and capabilities. Specifically, I would like to know the effective operating distance between the ball and the operator. Understanding this range is crucial for our intended applications, so any details you can provide would be greatly appreciated. Additionally, I'm curious about the possibility of integrating a 4G modem into the surveillance ball for use in Australia. This feature would be essential for enhancing connectivity and enabling functionality in remote areas. If you could share information on compatibility and options for this integration, that would be fantastic. Looking forward to your detailed response!
