An all-in-one desktop computer integrates the system's internal components into the same case as the display, thus occupying a smaller footprint than desktops that incorporate a tower.

The All in One form factor was popular during the early 1980s for computers intended for professional use such as the Kaypro II, Osborne 1, TRS-80 Model II and Compaq Portable. Many manufacturers of home computers like Commodore and Atari included the computer's motherboard into the same enclosure as the keyboard; these systems were most often connected to a television set for display. Apple has manufactured several popular examples of all-in-one computers, such as the original Macintosh of the mid-1980s and the iMac of the late 1990s and 2000s. Some all-in-one desktops, such as the iMac G4, have used laptop components in order to reduce the size of the system case. By the mid 2000s, many all-in-one designs have used flat panel displays, and later models have incorporated touchscreen displays, allowing them to be used similarly to a mobile tablet.

Like laptops, some all-in-one desktop computers are characterized by an inability to customize or upgrade internal components, as the systems' cases do not provide convenient access to upgradable components, and faults in certain aspects of the hardware may require the entire computer to be replaced, regardless of the health of its remaining components. There have been exceptions to this; the monitor portion of HP's Z1 workstation can be angled flat, and opened like a vehicle hood for access to internal hardware.

1) Bullet Camera: 

Bullet security cameras are a type video surveillance camera that are typically small and shaped like a rifle bullet shell or lipstick case. Smaller bullet cameras are typically the diameter of a cigar, but they are shorter. Sometimes they are referred to as lipstick cameras. Bullet cameras can easily mount to ceilings or walls because most of them use a tri-axis type of mount. Not all bullet camera are small. Infrared bullet cameras tend to be larger in diameter to accommodate the additional space that their IR LEDs require. There are several types of bullet cameras on this page including analog CCTV cameras, AHD cameras, and TVI cameras. The AHD and TVI models are capable of 1080p HD resolution, but require an AHD or TVI compatible surveillance DVR.

 

2) IP Camera:

 

 

An Internet protocol camera, or IP camera, is a type of digital video camera commonly employed for surveillance, and which, unlike analog closed circuit television (CCTV) cameras, can send and receive data via a computer network and the Internet. Although most cameras that do this are webcams, the term "IP camera" or "netcam" is usually applied only to those used for surveillance. The first centralized IP camera was Axis Neteye 200, released in 1996 by Axis Communications.

 

 

3) Dome Camera:

 

Dome Security Cameras are named for their dome like shape. Dome cameras are commonly used in surveillance systems inside of homes, casinos, retail stores, and restaurants. This is because dome cameras are more fashionable and blend in very well to their surroundings. Because of their dome shape, it is difficult for someone to tell which direction the lens of a Dome Camera is actually aiming. When shopping for a Dome Camera, you should consider if you need night vision, in which case you should look at an infrared dome camera. If the area that you are installing your camera is susceptible to vandalism or tampering, you should consider installing a vandal dome camera. A varifocal dome camera gives you the flexibility to adjust the focal distance of the camera lens to exactly where you need it. CCTV Camera Pros offers combinations of all of the above mentioned types of Dome Cameras.
