Abstract: When looking for a camera, you will see the term IP66 in the parameters of the camera. Now you may wondering what IP66 is. Here you can find the answer below.



        While you are looking for cameras you will come across the term: IP66,but what does it mean? IP66 is usually a rating of outdoor cameras and it defines the camera's ability to keep out foreign objects. The "IP" stands for Ingress (the act of entering) Protection. The first numerical digit (in this case being 6) describes the rating that is given for solid objects. The rating of 1, the lowest rating, defines the entering objects being greater than 50mm. The rating of 6, the highest rating, means the camera would be dust tigh. The second numerical digit (again in this instance a 6) defines how well the camera can keep liquids out. The rating of 1 means no special protection at all. The rating of 8, the highest rating, meaning the camera would be suitable for continuous submersion in water.


        Below is a chart that describes the rating of the two numerial digits that follow IP: 


 

Protection against solid objects

1st Digit

 Description

 Definition

 0

 Non-protected


 1

Protected against solid objects greater than 50 mm

 No special protection

 2

Protected against solid objects greater than 12 mm

A large surface of the body such as the hand (no protection against deliberate access). Solid objects exceeding 50mm diameter

 3

 Protected against solid objects greater than 2.5 mm

 Tools, wires, etc of diameter or thickness greater than 2.5 mm. Solid objects exceeding 2.5 mm diameter.

 4

 Protected against solid objects greater than 1.0 mm

Wires or strips of thickness greater than 1.0 mm. Solid objects exceeding 1.0 mm

 5

 Dust protected

 Ingress of dust is not totally prevented but dust does not enter in sufficient quantity to interfere with satisfactory operation of the equipment

 6

 Dust-tight

 No ingress of dust


 Protection against liquids

 2nd Digit

 Description

 Definition

 0

 Non-protected

 No special protection

 1

 Protected against dripping water

 Dripping water (vertically falling drops)

 2

 Protected against dripping water when tilted up to 15º

 Vertically dripping water shall have no harmful effect when the enclosure is tilted at any angle up to 15º from its normal position

 3

 Protected against spraying water

 Water falling as spray at an angle up to 60º  from the vertical shall have no harmful effect

 4

 Protected against splashing water

 Water splashed against the enclosure from any direction shall have no harmful effect

 5

 Protected against water jets

Water projected from a nozzle against the enclosure from any direction shall have no harmful effect

 6

 Protected against heavy seas

 projected in powerful jets shall not enter the enclosure in harmful quantities

 7

Protected against the effects of immersion

Ingress of water in a harmful quantity shall not be possible when the enclosure is immersed in water under defined conditions of pressure and time

 8

Protected against submersion

The equipment is suitable for continuous submersion in water under conditions, which shall be specified by the manufacturer

Can AHD System use Video Balun Connecting UTP to Achieve Signal Transmission?

Author: Selena      Source: www.mvteamcctv.com        Released on: Jan. 22,2015

 

Video Balun is the preferred choice by project engineers as it has the advantages in:
1)Better video image quality under longer distance transmitting than over coaxial cable
2)Strong anti-jamming capability
3)Easier wiring
4)Cost-saving

At present, more and more HD CCTV products are released in the market. When considering about the new products, users will think about whether they can transmit signal over UTP by hooking video balun or not.

Technicians from MVTEAM(Shenzhen CCTV Camera Supplier)tried this transmitting method in the new HD system-- AHD system.
The answer is "YES".
But two points should be paid attention to.

--How long can transmit over CAT5 cable?
   AHD System: around 200-250m
--What kind of Video Baluns can be used in transmitting HD signal?
   MVT-03T, MVT-03R, MVT-021, MVT-022, MVT-023, MVT-213AT
