The short answer
Yes — most modern CCTV cameras work at night using infrared (IR) for black-and-white footage in darkness, while low-light and spotlight cameras can capture colour after dark. Standard cameras switch to IR mode when light fades: built-in infrared LEDs illuminate the scene invisibly and the camera records in black and white, typically out to a stated IR range of several to many metres. Low-light (sometimes called "colour night vision") cameras use larger, more sensitive sensors to keep colour in dim conditions, and spotlight cameras add a white LED that floods the area with light and records in full colour while also deterring. Night performance depends on the camera, the IR or light range, and the scene — most incidents happen after dark, so this matters a lot.
Night vision is one of the most important features for home CCTV, because much activity worth recording happens after dark. The sections below explain how cameras see at night and what affects the result.

How infrared night vision works
Most CCTV cameras handle darkness with infrared (IR) night vision. As light fades, the camera switches to night mode: a ring of infrared LEDs around the lens emits light that is invisible to the human eye but that the sensor can see, illuminating the scene. Because IR carries no colour information, the resulting footage is black and white. You will often notice a faint red glow from the LEDs at the lens and hear a small "click" as an internal filter switches over. Each camera has a stated IR range in metres — the distance its LEDs effectively light — beyond which detail fades into darkness.
IR is reliable and works in complete darkness, which is its great strength. Its limits are range (subjects beyond the IR distance are poorly lit), and that very close, reflective objects — rain, spider webs, a nearby wall — can bounce IR back and wash out the image. Good placement, away from reflective surfaces and within the stated range of what you want to see, keeps IR footage clear.
Colour at night: low-light and spotlight cameras
For colour after dark, two approaches help. Low-light cameras (marketed as "colour night vision" or with names like Starlight) use larger, more sensitive sensors and wider apertures to gather what little ambient light exists — street lighting, a security light, moonlight — and keep a colour image in conditions where a standard camera would drop to black-and-white IR. They need some ambient light to work and are less effective in pitch dark. Spotlight (or floodlight) cameras take a more active route: a bright white LED switches on when motion is detected, flooding the area with light so the camera records full colour, while the sudden light also acts as a deterrent.
Colour footage is more useful for identification — clothing colour, vehicle colour — which is why these features are popular for driveways and entrances. The table compares the night-vision types.
| Type | How it sees | Result |
|---|---|---|
| Infrared (IR) | Invisible IR LEDs | Black & white, works in full dark |
| Low-light / colour | Sensitive sensor + ambient light | Colour, needs some light |
| Spotlight / floodlight | White LED floods scene | Full colour + deterrent |

Getting usable footage after dark
Whether night footage is usable depends on more than the camera buying it. Check the IR or low-light range matches the distance you care about — a camera with a short IR range pointed down a long drive will leave the far end dark. Position cameras to avoid pointing into street lights, security lights or low evening sun, which cause glare and silhouette people rather than showing their faces. Keep the lens clean and clear of cobwebs, and avoid mounting right next to a wall or under an eave that reflects IR back into the lens. A small amount of existing lighting around an entrance can dramatically improve a low-light camera's results.
Consider how the camera switches modes too: most flip to IR automatically at a set light level, and a spotlight camera triggers its LED on motion, so the first moment may be IR before the light kicks in. For identification at night, a spotlight or good low-light camera at a key approach is often worth the extra over a basic IR-only model. And the usual privacy rules still apply after dark — under the ICO's domestic-CCTV guidance, keep cameras angled within your boundary and footage no longer than necessary. With sensible placement, adequate range and the right night-vision type for the spot, modern home CCTV records perfectly usable footage through the night.
Frequently asked questions
Do CCTV cameras record in colour at night?
Standard cameras switch to infrared and record in black and white in darkness. To get colour after dark you need a low-light ("colour night vision") camera, which uses a sensitive sensor and some ambient light, or a spotlight camera, which switches on a white LED to flood the scene and record full colour.
How far can CCTV night vision see?
It depends on the camera's stated infrared or lighting range, given in metres. Subjects within that range are well lit; beyond it, detail fades into darkness. Choose a camera whose night range matches the distance you want to cover, and avoid reflective surfaces close to the lens that can wash out the image.
Why is my CCTV night footage washed out or glaring?
Common causes are infrared reflecting off a nearby wall, rain, cobwebs or a dirty lens, or the camera pointing towards a street or security light. Reposition the camera away from reflective surfaces and bright lights, clean the lens, and make sure nothing close to it is bouncing the infrared back into the sensor.
