ما هو نظام الإنتركم الصوتي وكيف يعمل؟

نظام الإنتركم الصوتي هو وسيلة اتصال داخلي تُستخدم للتواصل بين مدخل المبنى والوحدات، ويعتمد على نقل الصوت فقط من خلال وحدات داخلية وخارجية متصلة بكابلات، ويُستخدم بكثرة في الشقق والمكاتب.

ما هو الإنتركم المرئي وما مميزاته؟

الإنتركم المرئي هو نظام يتيح رؤية الزائر والتحدث معه من خلال شاشة داخلية وكاميرا خارجية، ويوفر مستوى أمان أعلى مع إمكانية تسجيل الصور وفتح الباب إلكترونيًا.

ما الفرق بين الإنتركم الصوتي والمرئي؟

الإنتركم الصوتي يعتمد على الصوت فقط، بينما الإنتركم المرئي يوفر صوت وصورة، مما يجعله أكثر أمانًا خاصة للمنازل والفلل.

هل الإنتركم يحتاج إلى إنترنت؟

لا، أغلب أنظمة الإنتركم تعمل بدون إنترنت، ولكن الأنظمة الحديثة مثل IP Intercom تحتاج الإنترنت فقط للميزات الذكية مثل التحكم عن بُعد.

ما هو الإنتركم IP؟

الإنتركم IP هو نظام يعمل عبر الشبكة ويوفر جودة أعلى وإمكانية التحكم عن بُعد وربطه بالموبايل وأنظمة الأمان الأخرى.

هل يمكن ربط الإنتركم بالموبايل؟

نعم، يمكن ربط الإنتركم بالموبايل في الأنظمة الحديثة، مما يسمح باستقبال المكالمات وفتح الباب من أي مكان.

هل يمكن تركيب الإنتركم في المباني القديمة؟

نعم، يمكن تركيب الإنتركم في المباني القديمة باستخدام أنظمة سلكية أو لاسلكية حسب طبيعة المكان.

هل الإنتركم يزيد من الأمان؟

نعم، الإنتركم يساعد في التحقق من هوية الزائر قبل فتح الباب، مما يزيد من مستوى الأمان بشكل كبير.
