The short version
- Typical range: £20 – £90 — see the full baby monitor value guide
- What decides your price: condition, and how well you evidence it in photographs
- Cost to sell here: nothing, at any price
- Category: Baby & Kids Items
Before you photograph it
Ten minutes here is worth more than anything else you will do. Buyers are deciding between your listing and someone else’s, and preparation is what visibly separates the two.
- Factory reset the monitor and remove it from your account entirely, then confirm it can be paired fresh.
- Test both units together and check the battery life on the parent unit, which is the part that degrades.
- Gather both power supplies, any wall mount and the original box if you have it.
The photographs that sell a baby monitor
Four photographs do almost all the work. Shoot in daylight, near a window, with the item against something plain — and do not use the flash, which flattens texture and hides exactly what buyers are trying to see.
- Both units together, powered on and paired, screens lit
- The parent unit screen showing a live picture
- Both power supplies, mounts and accessories laid out
- The model number on the back of each unit, plus any scuff or crack
Photograph the flaws too. It feels counterproductive, but a listing that shows the worst of an item gets fewer questions, fewer withdrawn offers and fewer arguments at handover. Buyers who can see the damage stop imagining something worse.
Writing the title and description
Brand, model and type: “Motorola Video Baby Monitor, 5in Screen, Model MBP…” or “Audio Only Baby Monitor, DECT”. Say video or audio, and whether it is a standalone camera-and-parent-unit pair or app based, because that distinction decides whether it still works at all.
Then state these in the description, because a buyer who has to ask is a buyer who might not bother:
- Brand, model number and whether audio or video
- Whether it works standalone or needs a phone app that is still supported
- Parent unit battery life as you actually observe it now
- What is included — both power supplies, mount, spare camera
What buyers will actually ask
You will receive the same three messages about a baby monitor. Answering them in the listing itself removes the back-and-forth, and answering them well when they do arrive is what turns an enquiry into a sale.
Answer directly. App-dependent monitors become useless when support ends, so if yours needs one, say which and confirm it is still available and accepting new accounts.
Factory reset it and confirm. A monitor still bound to your account is both a privacy problem for you and unusable for the buyer.
Time it and give a real figure. Rechargeable parent units degrade first, and an honest two hours is better than a claimed eight.
Pricing it so it actually sells
Start from the honest condition grade rather than the price you hope for. WishThrift listings use five grades — New with Tags, Like New, Good, Fair and For Parts — and what each grade means is worth reading before you choose, because grading up is the most expensive mistake sellers make. It does not raise the price; it produces a buyer who arrives expecting something else.
The baby monitor value guide prices all five grades for this item. Pick your grade, take the figure, and if you sit between two grades price toward the lower one. Items priced honestly sell faster than items priced hopefully, and on a free platform there is no fee eating the difference anyway.
What you keep, compared
On a £55 sale — roughly the middle of the range for a baby monitor — here is what the commission-charging platforms would take, and what you would keep on each:
| Where you sell it | Fee | You keep |
|---|---|---|
| WishThrift | £0 | £55 |
| Poshmark | −£11 | £44 |
| eBay | −£7 | £48 |
| Mercari | −£6 | £49 |
| Etsy | −£4 | £51 |
Seller-side rates verified 26 Jul 2026 — Poshmark: 20% commission on sales of $15 and above; eBay: 13.6% final value fee, plus a per-order fee; Mercari: flat 10% selling fee; Etsy: 6.5% transaction fee, plus a listing fee and payment processing. Percentages are applied to the sterling figure above; the fixed per-order and processing charges those platforms add are quoted in their own currency and are not included here, so the real deductions are slightly larger. Full breakdown: marketplace selling fees compared.
Timing and getting it to the buyer
Steady year round with a lift in spring and early autumn. Standalone video monitors from known brands sell within a week; app-dependent models are much harder and worth less.
Small and easy to post. Include both power supplies — they are often proprietary voltages and a monitor arriving without its charger is effectively broken.
WishThrift does not process payments or arrange delivery — you and the buyer agree both directly — so confirm payment has cleared before the item leaves your hands, and keep the conversation on the site so there is a record of what was agreed.

Frequently asked questions
What is a used baby monitor worth?
Typically £20 to £90, with recent video models at the top and old audio-only units at the bottom. The baby monitor value guide covers the grades.
Is it safe to sell a used baby monitor?
Yes, provided you factory reset it and remove it from your account first. Never hand over a camera still linked to your login, and tell the buyer to change any default password once it is theirs.
Are app-based monitors worth selling?
Only if the app is still supported and accepting new users. If the manufacturer has discontinued it, the hardware is genuinely dead and it is more honest to recycle it than to list it.
