GENERAL QUESTIONS ON CAMERAS

Can a camera see in total dark?

Cameras can not see in total darkness. You will need IR illuminators either built around the camera lens or as a separate lighting source (only for a B/W camera or a D/N camera). We do carry cameras that works in very low light conditions. Lower the lux rating, better it is under low light.

Do your cameras work with different voltage for other countries?

Most of our cameras come with a power adapter that can handle form 110V ~240V AC. In case you get a camera with direct AC plug-in such as clock radio camera we will include the 220V to 110V (60Hz) step-down converter. However, if your country uses 50Hz, the time on the clock, because it is digital, will not be correct (it will be off about 20 min a day)

How does a camera adjust to different lighting level?

Every camera has auto electronic iris built-in. Unlike a human iris or other camera, there is no mechanical diaphragm that controls light intake, rather shutter speed changes automatically. Level of adjustment is very wide from low light to very bright light. You can actually place the camera an inch away from a lit 100W light bulb and still be able to read clearly the label on the bulb.

How does a camera work with a bright spot lighting source.

All cameras come with auto-electronic iris control. In a case in low light the iris will open up and brighten the picture automatically (however limited to its lux rating)As long as the camera is not facing directly toward a light source in low light, it'll be OK. However if a light source would be on the screen, the iris will close thus darkening the picture of the surrounding.

How far or how much can you see with a camera?

Cameras can see Infinite, therefore It all depends on the size of the object. Wider the angle of the lens, smaller it will appear but area coverage will be greater. You can not have both zoomed in view and cover wide area. Most of our cameras come standard with wide angle lens (75 deg horiz) that will cover the whole room if placed at the corner looking towards the center of the room.

Try our CCD Lens Calculator for more information.

How much of a room can a camera view?

Most of our cameras come with around 4mm lens providing 75 deg in horizontal angle (for 1.3" CCD). That means if the camera is placed at the corner looking towards the center of the room, it'll cover most of the room regardless of its size.
Also all camera lenses are fixed focus and will focus to an object from about 2 ft away to infinity.
