IP66 چیست؟

منظور از IP67 و یا IP68 در دوربین مداربسته چیست؟

این سوالاتی است که ممکن است در ذهن هر کسی که به تازگی با دنیای نظارت تصویر آشنا شده باشد، پیش می‌آید. در این مقاله به معرفی و بررسی تکنولوژی IP66 و IP67 و IP68 در دوربین های مداربسته می‌پردازیم. 

 

 

 

IP (محافظت در برابر نفوذ) به چه معناست؟

اولین چیزی که باید بدانیم این است که در اینجا IP به معنای تحت شبکه نیست، بلکه به معنای درجه محافظت در برابر نفوذ (Ingress Protection Rating) یا درجه محافظت جهانی (International Protection Rating) می‌باشد.

که شامل حروف IP و به دنبالش دو عدد می‌باشد. بطور اختیاری یک حرف دیگر نیز می‌تواند بعد این دو عدد بیاید (مثال : IP66 یا IP69K).

همانطور که در استاندارد جهانی IEC 60529 تعریف شده، IP درجه حفاظت دوربین مدار بسته در برابر نفوذ اشیای جامد (شامل دست و انگشت افراد)، گردوخاک، تماس تصادفی و آب را درجه‌بندی می‌کند. این استاندارد تلاش دارد اطلاعات بیشتری نسبت به واژهای بازاریابی مبهمی مثل ضد آب، به مصرف‌کنندگان دوربین مدار بسته ارائه دهد.

اعدادی که بعد از حروف IP می‌آیند، میزان سازگاری با شرایط محیطی مختلفی که در جدول زیر آمده را نشان می‌دهند. بطور مثال یک سوکت با درجه حفاظتی IP22، در مقابل ورود انگشت و چکیده شدن آب محافظ است و آسیب نمی‌بیند.

IP22 یا 2X حداقل میزان درجه حفاظتی لازم برای تجهیزات الکترونیکی‌ای است که برای استفاده در فضاهای داخلی طراحی شده‌اند.

اولین عدد: جامدات

اولین عدد درجه حفاظتی، نشان دهنده میزان مقاوم بودن دوربین مدار بسته در برابر دسترسی به قسمت‌های پر خطر و ورود اشیای خارجی جامد می‌باشد.

 

درجهمحافظ در برابر اندازه شیموثر در برابر
0محافظت نشدهNo protection against contact and ingress of objects
1>50mmAny large surface of the body, such as the back of the hand, but no protection against deliberate contact with a body part.
2>12.5mmFingers or similar objects.
3>2.5mmTools, thick wires, etc.
4>1mmMost wires, screws, etc.
5Dust ProtectedIngress of dust is not entirely prevented, but it must not enter in sufficient quantity to interfere with the satisfactory operation of the equipment; complete protection against contact.
6Dust TightNo ingress of dust; complete protection against contact.

 

 

دومین عدد: مایعات

دومین عدد میزان حفاظت تجهیزات داخلی دوربین مدار بسته در مقابل ورود آب را نشان می‌دهد.

1Dripping waterDripping water (vertically falling drops) shall have no harmfull effect.
2Dripping water when tilted up to 15°Vertically dripping water shall have no harmful effect when the enclosure is tilted at an angle up to 15° from its normal position.
3Spraying waterWater falling as a spray at any angle up to 60° from the vertical shall have no harmful effect.
4Splashing waterWater splashing against the enclosure from any direction shall have no harmful effect.
5Water jetsWater projected by a nozzle (6.3mm) against enclosure from any direction shall have no harmful effects.
6Powerful water jetsWater projected in powerful jets (12.5mm nozzle) against the enclosure from any direction shall have no harmful effects.
7Immersion up to 1mIngress of water in harmful quantity shall not be possible when the enclosure is immersed in water under defined conditions of pressure and time (up to 1 m of submersion).
8Immersion beyond 1mThe equipment is suitable for continuous immersion in water under conditions which shall be specified by the manufacturer. Normally, this will mean that the equipment is hermetically sealed. However, with certain types of equipment, it can mean that water can enter but only in such a manner that it produces no harmful effects.
