Cameras capture images and sometimes sound and send the data to the monitors and recording devices. The most common styles of cameras are
bullet cameras and dome cameras. Certain cameras are designed for indoor and / or outdoor use, and some are bullet proof and vandal proof. You can mix
and match cameras as long as they use the same input cables.
Important things to know when deciding on a monitor to purchase:
- IR LED = Infrared LED, allows the camera to see in the dark.
- IR Distance = Infrared Distance, how far the camera can see in the dark.
- LUX = Illumination Rating, the amount of light required for a camera to capture in image. The lower the LUX, the less light that is needed.
- Vari-focal Lens = Allows view angle and the object distance to be changed.
- Field Of View = The height and width of the image seen by the camera in relation to the distance. Use our tool below to calculate the Field Of View
you want to help you determine the correct lens size.
- CCD Format = 1/3 Inch or 1/4 Inch CCD. (Charge Coupled Device) This converts images and sends it to the monitor and recording device. 1/3 Inch CCD is the most popular, it's
larger size allows more light to be captured. Although to the naked eye many people can't tell the difference in quality, 1/3 Inch would be preferred for monitoring dimmer areas.
- PTZ = Pan, Tilt, Zoom. A PTZ System allows the cameras to be remotely panned, tilted, and zoomed. In addition to special PTZ cameras you also need
