Dome Security Cameras get their name from their shape. You will find these cameras commonly installed in homes, casinos, retail stores, and restaurants. The main reason for the the popular demand of dome cameras is that it blends well with the surroundings. Their dome shape makes it difficult for a person to tell which direction the lens of a Dome Camera is facing. While 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 where the camera is to be installed is susceptible to vandalism or tampering, you should consider installing a vandal dome camera. Additionally, a varifocal dome camera gives you the flexibility to adjust the focal distance of the camera lens to exactly where you need it.
The Bullet security cameras are one of those video surveillance cameras that are ideally small and are shaped like a rifle bullet shell or a typical lipstick case. The smaller bullet cameras are usually equivalent to the diameter of a cigar, only they are shorter. Also known as lipstick cameras, these are used for security purpose. Bullet cameras can easily mount to ceilings or walls because most of them use a tri-axis type of mount. Though, 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 to record at nights.
Get yourself an IR bullet camera for low light and zero light applications.
As the name suggests, a pan–tilt–zoom camera (PTZ camera) is a camera that can be remote controlled and be given direction to. PTZ cameras play an important role in television production. The PTZ controls are actively used by professional videographers in television studios, sports events, and other spaces. These cameras are commonly referred to as robo. These cameras can be easily operated by automation systems. The PTZ controls are generally rented separately without the cameras, but are also available as a set, as in the case of Fletcher cameras.
PTZ reflects the movement options of the camera i.e. pan, tilt and zoom. Other types of cameras are PTZ or virtual pan-tilt-zoom (VPTZ) where a high-resolution camera digitally zooms and pans into portions of the image, with no physical camera movement. Ultra-low bandwidth surveillance streaming technologies use VPTZ to stream user-defined areas in higher quality without increasing overall bandwidth usage. Surveillance cameras of this type are often connected to a digital video recorder which records the full field of view in full quality.
PTZ Cameras are commonly used in applications such as surveillance, video conferencing, live production, recording lecture for distance learning.
