Situations
Outbuildings hold the things worth taking and get a fraction of the attention the house gets. Five products cover it: a shrouded padlock for the door, a combination lock so nobody carries a key down the garden, a weatherproof padlock for the gate, a standalone alarm that needs no hub, and a trail camera that needs no power.
A shed contains the tools, the bikes and the mower, and is often protected by a hasp held on with four screws.
Coach bolts through the door and frame with the nuts on the inside. Screws driven into the outside face of a shed are removed with the same screwdriver anybody carries, and no lock survives that.
Shrouded, so a bolt cropper has nowhere to sit. The one in this guide costs little. Measure the hasp first — shrouded locks have very little clearance.
A shed is reached through a side gate, and a corrosion-resistant padlock there is what stops the approach being casual. If a chain is used to anchor a bike or a mower inside, keep it taut and off the ground — a chain lying on a slab can be struck rather than cut, and concrete is a better anvil than any tool an opportunist carries.
A standalone alarm makes a noise where it is. A trail camera records with no power and no network, and it needs a cable lock of its own.
Often the most valuable thing in a garden, and the easiest to sell on.
Where locking the bike inside the shed matters as much as locking the shed itself.
Where a garage door is often the weakest point of an otherwise secure house.
Where a shed provides tools and cover for an attack on the house itself.
| The weakness | The fix | Why |
|---|---|---|
| Screwed hasp | Coach bolts through the door | Screws pull out of thin timber |
| Open padlock | A closed-shackle padlock | Resists bolt croppers |
| Exposed hinges | Hinge bolts | The door comes off otherwise |
| Valuables inside | A ground anchor and chain | Opening the shed is not enough |
Outbuilding security corrodes, literally. Padlocks left in weather seize, hasps rust, and timber around fixings softens over years until bolts that were solid can be worked loose.
Sheds contain hazards as well as valuables.
60 mm (2.36 in) cast-iron monoblock body · chrome-plated hardened bolt · shrouded shackle
A monoblock cast-iron padlock: the body encloses the shackle so that very little of it is exposed. KOTARBAU states a chrome-plated hardened steel bolt in a solid cast body.
Best for: A shed, a store or a gate where a cropper is the realistic threat rather than a curious hand.

4-digit combination · 7 mm (0.28 in) hardened shackle · zinc die-cast · 45 × 23 × 92 mm (1.77 × 0.91 × 3.62 in), 178 g (6.3 oz) · 5-year warranty
A four-digit combination padlock in solid zinc die-cast with a 7 mm (0.28 in) hardened shackle, dimensioned and weighed on the listing, and covered by a stated five-year warranty.
Best for: A shared lock — a gate several people use, a store cupboard, a locker — where distributing keys is the problem.
≈ $10
8 mm (0.31 in) shackle · extendable 60–150 mm (2.36 to 5.91 in) shackle · 281 g (9.9 oz) · paracentric key · ABUS level 6
ABUS's cellar padlock: an 8 mm (0.31 in) hardened shackle that extends from 60 to 150 mm (2.36 to 5.91 in), in a 281 g (9.9 oz) Titalium body, with a paracentric keyway and double shackle locking.
Best for: A hasp or a bracket where nothing standard reaches — cellar doors, old gates, awkward ironwork.
≈ $79
125 dB · 120° detection · remote control · doorbell or alarm mode · battery or USB-C
A standalone PIR alarm that needs no hub: 125 dB, a 120° detection field, a remote control, and a switch between doorbell mode and alarm mode. It runs on batteries or USB-C.
Best for: A garage, a shed or a shop doorway where a whole system would be absurd.
2K video · 24 × 850 nm IR LEDs · IP66 · camouflage housing · keyhole lock point
A camouflaged trail camera with 24 infrared LEDs at 850 nm and a front-opening body. CEYOMUR states 2K video with audio, an IP66 housing and a built-in keyhole for a lock.
Best for: A shed, a gate on a track or a plot with no power, where the camera should not be obvious.
A shrouded padlock, and coach bolts through the hasp with the nuts inside. Padlocks are cut at the shackle, and a monoblock body leaves nowhere for jaws to sit — while a hasp fixed with exposed screws is removed with a screwdriver whatever lock is on it.
A trail camera is, because it needs no power and no network. A conventional camera at the end of a garden needs both, and the cable is usually the reason the project never happens.
Usually the hasp is screwed into thin timber and pulls out. Bolting through the door with coach bolts changes it more than a better padlock does.
Exposed hinge pins let the door be removed entirely. Hinge bolts or concealed hinges close that route.
Yes. A ground anchor and a good lock mean that opening the shed does not automatically mean losing the contents.
Yes, especially where the shed sits in the dark. Removing darkness and improving sightlines both matter.
Often only up to a limit and sometimes only with specified locks. Check the wording before assuming the contents are covered.
Designed for: A shed, a store or a gate where a cropper is the realistic threat rather than a curious hand.
Its main asset: Monoblock construction shrouds the shackle — the single biggest step up in this family
Its main gap: Heavy, and it will mark a painted gate
Designed for: A shared lock — a gate several people use, a store cupboard, a locker — where distributing keys is the problem.
Its main asset: No keys to cut, lose or distribute
Its main gap: A combination is only as private as the people who know it

Its main asset: Completely standalone — no hub, no app, no account
Its main gap: No notifications — it makes a noise where it is, and nothing else
Designed for: A shed, a gate on a track or a plot with no power, where the camera should not be obvious.
Its main asset: Camouflage housing that genuinely disappears against bark and hedge
Its main gap: 850 nm LEDs emit a faint visible red glow — they are not invisible

Accessories and spares from the same aisle, at the price we read. Confirm they suit the device you choose before ordering: it turns on the model and the part number, which the listing gives.
Device against device, already covered, inside this guide or this aisle.
The devices listed are drawn from the catalog of this site. Specifications are those the maker and the Amazon listing publish; prices are what Keepa recorded on the date shown, and both move. The order follows declared specifications, the balance between stated strengths and stated limits, and price. No device here has been installed or tested by us, and no page claims it was.

Prices quoted in these summaries are dated readings. The live price is shown next to each product.
Cameras, alarm kits and safes swing by thirty dollars or more across the year, and the biggest "discounts" often land at prices the same model sold for six weeks earlier. UniverTrack tracks the real price history across retailers, spots fake reductions, and alerts you when it is genuinely the moment to buy.
