No mains, no network, and it runs for a season on AA cells · review
CEYOMUR CY40 review
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.
The conclusion The cheapest way to watch a place with no power. Buy a lock for it at the same time.
A trail camera exists to watch somewhere with no mains and no network — the
end of a garden, a gate on a track, an allotment, a plot with a building on
it. This is the least expensive competent one here.
What it does
2K video with sound, 24 infrared LEDs at 850 nm for the dark, an IP66
camouflage housing that opens from the front rather than needing to come off
its strap, and a small screen for setting it up and reviewing what it caught.
The wavelength, which is the choice in this family
850 nm LEDs produce a faint red glow visible to anyone who looks directly at
the camera, and reach further. 940 nm LEDs are invisible and reach less far.
For wildlife the glow is irrelevant. For watching a gate discreetly, it is the
whole point, and this camera is the wrong one.
The keyhole is not a detail
A trail camera is small, worth something and left alone in a place nobody
watches. The integrated keyhole takes a cable lock around the tree or post it
is strapped to. Without one, the camera and everything it recorded leave
together — which is a failure mode unique to this family and entirely
preventable for a few dollars.
What is not published
No trigger speed. It is the figure that decides whether an image shows a
subject or the space they have already left, and where a maker does not state
it we do not guess. If what you are watching moves quickly across the frame,
choose a camera that publishes the number.
Who it suits
A watching job with no power and a modest budget. Buy a lock, a card and
batteries with it.
Availability
Not found on the American Amazon store, where the buy link falls back to a local search rather than to a page that does not exist.
Prices and availability are what Keepa reported on the date this page was updated; both move.
What reassures, and what does not
Strengths
Camouflage housing that genuinely disappears against bark and hedge
24 infrared LEDs for night illumination
Built-in keyhole so the camera can be locked to what it is strapped to
IP66 housing, and a front-opening design that is easier to service in place
Compromises
850 nm LEDs emit a faint visible red glow — they are not invisible
No trigger speed published on the listing
Card and batteries not supplied
No Wi-Fi: images are collected by visiting the camera

The questions we are asked
What is the difference between 850 nm and 940 nm?
Visibility. LEDs at 850 nm emit a faint red glow that a person can see if they look at the camera, and they illuminate further. LEDs at 940 nm are invisible to the eye and reach less far. For wildlife, 850 nm is usually fine; for watching a gate discreetly, 940 nm is the choice.
Why does the keyhole matter?
Because a trail camera is small, valuable and left alone in a place with nobody watching it. A cable lock through the keyhole and around the tree or post is the difference between a camera that is there next month and one that is not — and the camera takes its own card with it when it goes.
No trigger speed is published — is that a problem?
It is the single most important figure in this family, and where a manufacturer does not publish it we do not estimate one. Judge this camera on what it does publish, and prefer a model with a stated trigger time if what you are watching moves quickly past.

The buyer this one serves, among security devices
A shed, a gate on a track or a plot with no power, where the camera should not be obvious.
Specifications: the manufacturer sheet for home security products and the matching Amazon product page. Prices and availability: Keepa. Every figure on this page names its source.
64MP stills · 1296p H.264 video · Bluetooth and Wi-Fi pairing · 36 × 940 nm LEDs · no monthly fee
GardePro pairs by Bluetooth before switching to Wi-Fi, which removes the step where trail-camera apps usually fail. It states 64 MP stills, 1296p H.264 video, 36 no-glow LEDs and an external high-gain antenna, with no subscription.
Best for: Anyone who has already given up on a trail camera app once.
4K · 32MP · 940 nm no-glow to 24 m (79 ft) · 0.1–0.3 s trigger · −29 to 21 °C (-20 to 70 °F) rated · IP66
HSSNS states 4K video, 940 nm no-glow night vision to 24 meters (79 ft), a trigger of 0.1 to 0.3 seconds with three-shot bursts, and operation rated from −29 °C (−20 °F) to 21 °C (70 °F), with a 2.4-inch color screen and password protection.
Best for: A cold, exposed position where the camera has to keep working through a winter.
2K · 36MP stills · 940 nm no-glow · 0.2 s trigger · clamshell body · illuminated keypad
iZEEKER publishes the figure that matters — a 0.2 second trigger — alongside 940 nm no-glow infrared, 2K video, three-shot bursts and a clamshell body with a bottom-opening battery compartment.
Best for: Watching a gate or a track discreetly, where nobody should be able to see the camera working at night.
