Comparisons
Dome vs bullet cameras
Use dome cameras indoors for wide coverage of rooms and corridors, and bullet cameras outdoors where you need to see detail at distance. Bullets give a better night picture at range because the infra-red sits away from the lens. Most premises need both rather than one or the other.
Coverage shape
A dome sees wide and near. A bullet sees narrow and far. Choose from the distance you need to identify something at, not from how the camera looks on the wall.
Night performance
Bullets win at range. Their illuminator sits forward of the lens so less infra-red reflects back. Domes suffer more from glare, especially once the cover picks up dust.
Tampering
Domes are harder to re-aim by hand and vandal-resistant versions take a knock. Bullets on arms can be pushed out of aim, which is why mounting height matters more for them.
Should I use dome or bullet cameras?
Which is better for a shop?
Domes inside for the floor and corridors, one bullet outside covering the frontage and doorway. That combination costs the same as an all-dome system and works considerably better.
Are domes more discreet?
Slightly. The rounded cover hides which way the lens points, which some owners prefer. In practice most people assume any camera is watching them, so the deterrent effect is similar.
Need this doing?
CCTV installation covers surveying your premises, choosing camera positions that actually cover your entrances and till, running cable in conduit, fitting the recorder with enough storage for your retention needs, and setting up phone viewing before we leave. A four-camera system typically costs PKR 45,000 to 70,000 installed.
