Top Questions

Q

How to solve the HD transmission delay in video monitoring?

A

SDI adopt non compression real time transmission program, which is the best HD solution in video monitoring for the moment.

Q

How to upgrade video monitoring system to HD monitoring system?

A

The framework for SD-SDi and HD-SDI is the same. Only to exchange some relative equipment can we upgrade the SD-SDI system to HD-SDI system.

Q

How to avoid the compatibility problem between video monitoring HD equipments?

A

SDI equipment comply to uniform mature SDI standard, which can be used once it is connected. So there will be no compatibility problem occurring.

Q

How is the compatibility of POE switch products in million HD monitoring projects and PD IP camera?

A

Some IP camera factory adopt personalized design, which results in some problem in compatibility. All of ONV POE series products adopt international standard design, totally meet IEEE802.3af and IEEE802.3at standard design request, so in principle, our POE switch products are compatible with all international standard IP camera. In early stage, some IP camera factory adopt personalized power receiving design, and some abnormal phenomena occurs. In order to make ONV brand POE switch serve customers better, ONV R&D team tested the compatibility of our POE switch with 26 oversea brand POE IP camera factory and 193 national brand POE IP camera factory, and optimized the compatibility of ONV brand POE switch in details. This makes our POE switch generally meet the compatibility request with IP camera for projectors.

Q

In actual project application, if we choose Ethernet power supply function, then only a POE switch can not meet our needs in projects. How should we solve this problem?

A

Limited kinds of POE products make the networking inconvenient. While there are many types of POE series products in ONV. Based on function, there are POE switch, POE splitter, POE splitter line, POE extender, POE injector, POE fiber transceiver, and POE fiber switch. Based on port, there are single port, 4 ports, 8 ports, 16 ports, and 24 ports. Based on bandwidth, there are 100M, 1000M, and total 1000M. Based on other classification, there are web managed and unmanages, industrial used and home used, IEEE802.3af standard, IEEE802.3at standard and super high power standard. With so many types of POE products, it enriches projector’s choice in networking and make it much easy.

Q

There are so many kinds of POE switch in the market, how can we distinguish quality ones from fake ones?

A

There are many company make great benefits by selling fake POE switch in high price. ONV company has more than 10 years’ experience in this industry, and adopt international standard intelligent energy efficiency classification technology, which support IEEE802.3af and IEEE802.3at standard separately. The most basic way to distinguish is to use avometer to test if the networking line pair for electric energy transmission is with 48V voltage. True POE switch can not test 48V voltage, while fake POE switch can test out differential pressure. Fake POE switch will do great harm to customers. It will burnout networking equipment, and what’s worse, it can cause circuit shot which will results fire.
