The maximum distance from a midspan to a camera requiring PoE+ (25.5 W) is 100 meters (328 feet). This distance limitation is due to the standard Ethernet cable length limit, ensuring effective power delivery and data transmission over the network.

Multicast is great for local networks, but not for the internet!

Wait, are RTSP streams really always multicast? That sounds off.

Definitely, multicast allows for more viewers without extra load!

I disagree, multicast isn't reliable for internet streaming.

I feel like option B is misleading; I recall that multicast can be used for video over the internet in some cases.

I practiced a similar question where we discussed viewer capacity, and I think option D might be correct too.

I'm not sure about option C; I thought multicast typically uses UDP instead of TCP for streaming.

I remember that multicast can save bandwidth, so I think option A is definitely true.

I remember learning about multicast in class, but I can't recall all the details. I'll just do my best to select the three correct statements.

Multicast is definitely used for video streaming, but I'm not sure about the specifics of how it extends viewer capacity. I'll have to guess on that one.

Okay, let's see. I know multicast is used to save bandwidth, but I'm not sure about the other details. I'll have to read the options closely.

Hmm, I'm a bit unsure about the differences between multicast and other video streaming protocols. I'll need to think this through carefully.

I'm going to have to go with the classic 'all of the above' on this one. Multicast is just too powerful to be limited to three options!

This is a tricky one, but I think A, D, and E are the way to go. Multicast is great for video streaming, even if it can't handle unlimited viewers.

Multicast does not use TCP as transport protocol, so that statement is also false.
TA

RTSP streams are not always sent through multicast, so that statement is false.
LA

Yes, multicast does extend the viewer capacity from 10-20 to unlimited.
JU

I agree, multicast can definitely save bandwidth.
DA

Haha, D is a bit of a stretch. Unlimited viewers? I wish! But A and E seem like the real winners here.

I agree with Lynda, multicast can save bandwidth and extend viewer capacity.
LI

B and C are definitely wrong. Multicast is typically used over the internet, and it uses UDP, not TCP.

I think B is false because multicast can be used over the internet.
AN

A and D seem like the correct answers here. Multicast can definitely save bandwidth, and it can also extend the viewer capacity of a camera or encoder.

A, D, E are true.
