CCTV Night-Vision Range Planner
The IR range on a datasheet is a best case, measured against a reflective wall. Enter that stated range, how reflective your scene is, and how far your target sits — this derates it to a realistic detect range and a realistic identify range, then tells you whether the camera's own IR actually covers your target at night. Planning figures; runs in your browser.
- Stated IR range30 m
- × reflectivity (Medium)×0.7
- = realistic detect21.0 m
- × identify factor (0.45)9.5 m
Planning estimate only — IR range depends on the scene, weather, dirt on the dome (IR bounce off the glass) and the camera sensor. Treat these as planning figures, then test at night on the actual site. If the camera also lights or points at a shared corridor, street or a neighbour's space, add a clear signage notice and keep the view to your own boundary — a DPDP Act 2023 courtesy; consult a professional for compliance.

Security Lighting vs Infrared Illumination in India (2026): Which Lights Your Cameras at Night?
Visible white security lighting deters intruders and gives colour and facial detail to the naked eye and the camera; invisible infrared (IR) lets a camera see in total darkness without light pollution or a power-hungry floodlight. They solve different problems, and most good setups use both, thoughtfully.

A homeowner's head-to-head between traditional infrared (IR) night vision, which lights the scene invisibly and shows a black-and-white image, and colour night vision, which keeps the picture in colour at night using a very sensitive sensor and a little white light — with an honest verdict on when each wins and why a hybrid camera is usually the smartest buy.
