Bullet Cameras vs. Dome Cameras. Bullet cameras and dome cameras are the most common camera types used for home and business security today. Both are easy to install, manageable, and offer complete control to the user when securing areas of any size.
The camera is a remote sensing device as it senses subjects without any contact . The word camera comes from camera obscura, which means "dark chamber" and is the Latin name of the original device for projecting an image of external reality onto a flat surface.
There are basically two options when it comes to day&night cameras. A true day night camera has the ability to automatically switch from color to black and white when the lighting gets below a certain point. A Day night camera can see in very low light conditions without the assistance of infrared illuminators.
Winner: PTZ Cameras. Simultaneous Users. Live cameras can either serve streaming video or still images. With streaming video, only one user will be able to control a PTZ camera at any time. Other users will be forced into a queue. With live images, it is possible to avoid queues. With ePTZ, there is never a queue since the camera does not need to move.
