Hikvision 4-Inch Analog Wall Speaker 20W DS-QAE0120G1E-V

The DS-QAE0120G1E-V is a 4-inch analogue wall speaker rated at 20 W, and on most jobs that 20 W matters more than anything else printed on the box. It sits at the louder end of Hikvision’s analogue wall range: the point for spaces where sound has to carry over machinery, traffic or a crowd.

On a quotation, though, it behaves less like a speaker and more like a line item on a budget. Every speaker on an analogue line spends part of what the amplifier can deliver, and a 20 W point spends several times what a small one does.

Where it earns its place on a job

The amplifier has a power budget and the speakers spend it, so the count comes before the model. That is the arithmetic that decides an audio quotation, and almost nobody does it before ordering. The total drawn by every speaker on a line has to sit inside what the amplifier can deliver, with headroom left over, so a system designed with the big speakers everywhere runs out of amplifier long before it runs out of rooms.

So work in this order. Draw the zones, because zones are what the client will page and mute independently. Count the points in each. Choose a size to suit what each space genuinely needs rather than defaulting to the largest, so a quiet corridor gets a small point and only the noisy areas get a 20 W one. Total it. Then choose the amplifier: with the figures in front of you, the six-zone 240 W analogue amplifier DS-QAE0A240G1-VB6 is either comfortably big enough or obviously not, and you know it before the van is loaded. Never the other way round.

The commonest audio redesign we see is caused by specifying speakers first and discovering the amplifier afterwards. Adding one more speaker to a line already at its limit does not make the system quieter — it makes the amplifier work outside what it was sized for.

Before you order — three things to confirm

• The zone list, with a point count per zone. Send us that before we quote: a five-minute job on a floor plan, and the only thing that tells us whether 20 W points are the right call here.
• What is already on the line. If you are extending an existing system, we need the amplifier model and everything connected to it. Spare capacity is never safe to assume.
• That this space needs the larger speaker. A 20 W point earns its keep where there is real background noise; in a quiet office run a smaller one does the same job and leaves budget elsewhere.

Compatibility

This is an analogue speaker and belongs on an analogue public address amplifier, alongside Hikvision’s other analogue wall, ceiling and horn points. Mixing sizes is normal practice; what has to be checked is the total load, and that everything sharing a line is built to the same analogue standard. Send us the amplifier and speaker list and we will check both.

What’s in the box

Supplied contents vary by manufacturing revision, so we confirm what ships with your units on the order rather than print a list that may be out of date. Anything else is a separate line.

Common questions on this model

How many of these can I run?
That depends entirely on the amplifier and on what else is already on the line — there is no honest fixed number for a speaker on its own. Send us both and we will work it.

Can I mix these with smaller speakers on the same system?
Yes, and you generally should. Sizing each space separately puts the 20 W points where they are needed and keeps the total inside the amplifier’s budget.

We want to add two to a system installed a few years ago. Is that safe?
Only if the amplifier has spare capacity, which is a question about the existing installation, not about this speaker. Give us the amplifier model and the current point count.
