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.

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.
