Camera response
Confirm that the camera enters monochrome mode and responds well to 850nm light.

850nm IR Illuminators for CCTV, LPR and Long-Range Night Vision
850nm infrared illumination is a practical starting point when a monochrome or day/night camera needs strong night-time response. The correct unit still depends on the camera sensor, lens field of view, target distance, mounting position and ambient light, so selection should be confirmed with the complete camera setup.
Decision First
Check these factors before choosing a model
Field of view
Match the illuminator beam to the camera view so light is not wasted outside the image.
Target zone
Measure the real distance and width of the area that must be illuminated.
Outdoor conditions
Choose the housing, input voltage and control method for the installation environment.
Selection Snapshot
Compare the project conditions
| Selection point | Choose this direction | Verify before ordering |
|---|---|---|
| General CCTV | Continuous 850nm illumination | Camera sensitivity, lens view and ambient light |
| Vehicle capture | Focused or synchronized 850nm lighting | Trigger compatibility, shutter settings and lane geometry |
| Wide scene | Medium or wide beam | Edge brightness and mounting height |
| Distant target | Narrower beam or higher-output configuration | Camera lens, weather and real site test |
Where 850nm IR is commonly considered
850nm is widely used for CCTV night vision, vehicle access, ANPR assistance, yards, warehouses and perimeter monitoring. It is often selected when usable camera response is more important than minimizing the faint red glow that some emitters may show at close range.
The illuminator is only one part of the imaging chain. Sensor response, lens aperture, shutter speed, gain, reflective surfaces and mounting geometry can change the result, so a sample should be tested with the intended camera.
Match beam angle to the camera, not to a wattage label
A narrow beam concentrates energy into a smaller target zone, while a wider beam covers more of the scene. Neither is automatically better. The correct choice is the beam that overlaps the camera field of view at the required distance.
Before model matching, provide the camera model, lens or horizontal field of view, distance to target, mounting height, target width and any nearby reflective surfaces.
Define a safe performance boundary
Accurates supplies infrared lighting and selection support. Image quality, license-plate recognition and analytics performance depend on the full camera system and site, and must be verified by customer or project testing.
For procurement, confirm the selected model's wavelength, beam, housing rating, voltage, control method and mounting hardware on the final datasheet or quotation.
Project Recommendation
Not sure which 850nm configuration fits?
Send the camera model, target distance, field of view and mounting position. We will narrow the wavelength, beam and control options before sampling.
Clear Answers
Frequently asked questions
Is 850nm suitable for every security camera?
No. Many day/night cameras respond to 850nm, but response varies by sensor, IR-cut filter behavior, lens and camera settings. Test the intended camera before final approval.
How do I choose the beam angle?
Match the beam footprint to the camera field of view at the target distance. Send the lens or field of view, target width, distance and mounting height for a recommendation.
Can an 850nm illuminator guarantee ANPR accuracy?
No. It can support image capture, but recognition also depends on camera exposure, lens, plate angle, vehicle speed, trigger timing and software. Validate the complete system on site.
What information is needed for a quotation?
Share the application, camera model, distance, target width, voltage, control method, quantity, destination and any outdoor or certification requirements.
