Dome Cameras — FC5D 5 MP Full Colour
A 5 MP dome module for lobbies, corridors and retail floors, where the direction of view should not be obvious and the camera should not be easy to grab. Same sensor and same night behaviour as the bullet.
- 5 MP at 2880 × 1620
- Discreet viewing direction
- H.265+ encoding
- Two-way audio
Why interiors usually want a dome
Two practical reasons. First, nobody standing underneath can see where a dome is pointing, so the coverage is less easy to avoid. Second, a dome sits flush against the ceiling, which matters in a corridor or a retail floor where a bullet on a bracket looks like a maintenance problem waiting to happen.
The form also survives contact better. In a lobby or a corridor at standing height, the camera is within reach, and a dome in a suitable housing is far harder to knock off aim than a bracket-mounted bullet.
Coverage planning for interiors
- Corridors: place at the end looking down the length, not in the middle looking sideways. One camera covers the whole run and you only need one cable.
- Lobbies: cover the entrance from inside, so you record faces as people come in rather than backs as they leave.
- Retail floors: point at the till line and the stock-room door, not at the aisles. Aisles generate motion and no evidence.
- Lift lobbies: one camera per floor lobby covers the lift doors and the corridor mouth at once.
- Ceiling height: keep the camera above 2.4 m so nobody can reach it comfortably, but below 4 m so the angle on faces stays usable.
Night behaviour indoors is different
Indoor night is rarely truly dark. Emergency lighting, exit signage, vending machines and street light through glazing usually leave more than 0.1 Lux on the floor, which is inside the colour range of the F1.0 optics. That is the case where the low-light specification genuinely shows: an unlit corridor after hours still records in colour, so a person's clothing is describable.
Where a corridor does go fully dark, the camera falls back to its own illumination and to black and white. That is normal and we would not describe it as a fault — but if colour after dark is the reason for the project, check the site with a light meter before you commit.

Frequently asked questions
Is a dome better than a bullet indoors?
Usually, for two reasons that have nothing to do with image quality: the viewing direction is not obvious from below, and a flush dome is harder to knock off aim at standing height. The sensor, resolution and night behaviour are identical, so you are choosing a mounting form rather than a performance level.
Does the dome housing come with the camera?
The camera is a 38 × 38 mm board module and the housing is selected separately. That is deliberate — the right housing depends on whether the position is a plasterboard ceiling, a lift car, an exposed car park soffit or a vandal-prone stairwell, and those need different answers.
Will it record in colour in a corridor at night?
Usually yes, provided there is some residual light. Emergency lighting, exit signage and light through glazing typically leave more than 0.1 Lux, and 0.1 Lux is where the colour threshold sits at F1.0. If the corridor goes completely dark, the camera falls back to black and white with its own illumination.
How many domes do I need per floor?
For a typical office floor, one camera per lift lobby, one at each stair door, and one per corridor run covers the circulation without pointing into any desk area. A 20-floor tower usually lands between 60 and 110 cameras in total. Send us a floor plan and we will mark up positions for you.
Can it be mounted on a wall rather than a ceiling?
Yes, with the appropriate wall bracket, though a wall-mounted dome gives a partial view of the surface behind it. For corridors, a ceiling mount looking along the run is almost always the better geometry.
Does it have the same audio and alarm features as the bullet?
Yes. Audio input and output, G.711 encoding, two-way intercom, motion detection, smart algorithm linkage, the red-blue warning light interface and the same 6 KV network surge protection are common to the whole FC5 board series.
