Så længe kameraet virker, kan min veninde deltage i mødet hjemmefra.

Here, så længe means as long as.

It introduces a condition:

• Så længe kameraet virker ... = As long as the camera works ...

A learner may also see så længe in other contexts meaning for so long, but in a sentence like this, followed by a full clause, it usually means as long as.

Because kameraet is the definite singular form: the camera.

In Danish, the definite article is often added to the end of the noun:

• et kamera = a camera
• kameraet = the camera

Since the sentence is talking about a specific camera, Danish uses kameraet.

The ending -et marks the noun as:

• singular
• definite
• and belonging to the et-word gender group

So:

• et kamera = a camera
• kameraet = the camera

This is very common in Danish. Compare:

• et møde → mødet
• et hus → huset

Virker is the present tense of virke, meaning to work / function.

Danish present tense is usually formed by adding -r to the infinitive:

• virke = to work
• virker = works / is working

So:

• kameraet virker = the camera works / the camera is working

This is because Danish follows a verb-second pattern in main clauses.

When the sentence starts with something other than the subject, the finite verb comes before the subject in the main clause.

Here the sentence begins with the subordinate clause:

• Så længe kameraet virker, ...

Then the main clause starts, and Danish puts the finite verb first:

• kan min veninde deltage ...

So the structure is:

• subordinate clause
• then verb + subject in the main clause

If the main clause stood alone, it would be:

• Min veninde kan deltage i mødet hjemmefra.

But after the fronted clause, it becomes:

• Så længe kameraet virker, kan min veninde deltage i mødet hjemmefra.

Because after a modal verb like kan, Danish uses the bare infinitive.

So:

• kan deltage = can participate
• not kan deltager

Compare:

• Jeg kan komme = I can come
• Hun kan arbejde = She can work
• Vi kan deltage = We can participate

This is similar to English:

• can participate
• not can participates

Kan is the present tense of kunne, and here it means can / is able to / is able to manage to.

In this sentence, it expresses possibility or ability, depending on context:

• kan min veninde deltage i mødet hjemmefra
  = my female friend can participate in the meeting from home

Because of the condition at the start, the idea is roughly:

• If the camera works, then she is able to join.

Yes. Veninde means female friend.

• ven = male friend or sometimes just friend in some contexts
• veninde = female friend

So min veninde means my female friend.

This is one of the places where Danish makes a gender distinction that English usually does not.

The verb deltage normally goes with the preposition i.

So Danish says:

• deltage i noget = participate in something

That is why you get:

• deltage i mødet = participate in the meeting

This is something that simply has to be learned with the verb.

Because mødet means the meeting, while et møde means a meeting.

Here the sentence refers to a specific meeting, so Danish uses the definite form:

• et møde = a meeting
• mødet = the meeting

Just like kameraet, mødet is an et-word, so the definite singular ending is -et.

Hjemmefra means from home.

It is built from the idea of:

• hjemme = at home
• fra = from

But in Danish, hjemmefra is very commonly written as one word.

So:

• deltage i mødet hjemmefra = participate in the meeting from home

This is different from just hjemme, which means at home, not necessarily from home.

Yes. A very natural alternative is:

• Min veninde kan deltage i mødet hjemmefra, så længe kameraet virker.

This means the same thing.

The difference is mainly emphasis and flow:

• Så længe kameraet virker, ... puts the condition first
• ..., så længe kameraet virker puts the condition later

Both are correct.

Yes.

It is a subordinate clause introduced by så længe.

That matters because it helps explain the word order in the rest of the sentence. After this fronted clause, the main clause follows with inversion:

• kan min veninde ...

So this sentence is a good example of:

1. a subordinate clause first
2. then a main clause with verb before subject

A rough guide is:

• hjemmefra ≈ YEM-uh-fra

A few helpful points:

• hj in modern Danish often sounds close to y
• the first part hjemme sounds roughly like yem-uh
• fra sounds a bit like English frah

As always with Danish, the exact pronunciation can be softer and more reduced than the spelling suggests.

Yes, virke can have more than one meaning depending on context.

Common meanings include:

• to work / function
• to seem / appear

In this sentence, because the subject is kameraet, the natural meaning is:

• the camera works / functions

So here it is definitely about the camera functioning properly.

It sounds natural and neutral. It works well in both everyday and fairly standard written Danish.

Nothing in it is especially slangy or highly formal. Expressions like:

• så længe
• deltage i mødet
• hjemmefra

are all very normal Danish.
