葡萄牙采购需求：录音拦截器、音频隐私保护、录音机隐私、录音预防、反间谍设备、防止音频监控

I'm looking for detailed info on signal jammers for an upcoming project. Specifically, I need to understand the different types of jammers available, their specifications, and potential applications. Could you send me any brochures or catalogs that outline features and pricing? Additionally, it would be helpful to know about the lead times for these products, any minimum order quantities, and if you offer customization options. If you have any recommendations based on current market trends or popular models, I'd love to hear about those as well.
