NAN

Great questions!

 

A SAN (Storage area network) is normally used to expand storage for cameras in large IP/CCTV systems. The NVR/Server will handle the recording and use a SAN to store the video. Most SANs consists of iSCSI and Fiber Channel Storage. iSCSI is a IP based storage networking standard which allows you to use IP networks for a transport. It is like a NAS but provides block level access. FCP (Fiber Channel Storage) allows you to connect your NVRS/Servers to SAN units via fiber.

 

Having deployed both iSCSI and FCP for large projects I would recommend FCP as is faster and more reliable.

 

Also Bosch cameras can connect directly to SAN storage from the cameras. https://us.boschsecurity.com/us_product/05_news_and_extras_2/01_productnews_2/03_productnews_video_1/bosch_video_recording_manager/video_recording_manager

Thank you but in case we are using NVR that stores in SAN what about the disks in NVR, it will be not used ?

Hi,

what the differences between the NVR and other storage as SAN.. if the camera stream recorded and stored in NVR why to use an another storage as SAN in some projects ?

If the NVR can store the camera videos for a long time where this depends on the NVR specifications, is it mandatory to have SAN storage in the network ? and can we use SAN instead of NVR.. like recording the stream directly to the SAN.

from what I can tell you would still need to convert analog to digital to be able to view over the networtk.

Thanks.

is there any differences between the media converter and balun ?

I have a general question, as you know in analog cameras we need encoders to converts the signals to a digital signal in order to connect it to other digital devices through the network such as NVR.

in case we are not using any kind of recording devices and the cameras will be connected through Ethernet network, can we get rid off the encoders ?

 

Your question isn't very clear. What kind of "encoder" are you talking about?

encoders that convert the signals of the cameras from analog to digital signals.

It has been a long time to thank you , but really thank you ericq, each time I get confused I back to your answers

No one : ( ?

 

 

 

Many have read your post ...... But to answer your questions right would mean typing for hours page after page

thank you tomcctv.

it's not expected from one person to answer all questions.

and thank you for the glossary : )

Hi All " title="Applause" /> ,

I need to have a good understanding for the camera conductivities and I will with your support : )

I'm a beginner in this field and I have list of questions so please if you know any one of it kindly benefit me

Q's:

1- How to know from the datasheet of the camera if it's analog or digital?

2- Is this a model of camera or a company ( NKF )?

3- Can we use CAT6 with analog camera ? if yes why in some cases we are using COAX ?

4- why to use the Video Tx and Rx for the analog cameras and why we connect them to fiber optic cable, is it

because the long distances?

5- Can we use the COAX for the long distance?

6- when to use the RJ 45 connector?

7- How they calculate the network bandwidth? which calculations and formulas they used?depending on what?

8- Is SFP in switches 1 GbPs or 10 Gbps?

9- why we connecting the encoder to the industrial switch with CAT6 not FO.

Thank you in advance.
