Dome cameras are either ceiling mounted or suspended from a wall mounted bracket depending on the application and the field of view required. The camera unit is mounted inside a transparent dome which can be tinted to obscure the camera position. Dome cameras come in a wide variety of forms.
Dome cameras are also available in mini- and micro- versions for discrete deployments and are available in a range of housings to suit various architectural styles
Bullet cameras are multi-functional, durable indoor/outdoor security cameras. Bullet Security Cameras are built for the outdoors and are often waterproof, weatherproof, or otherwise made to endure harsh weather conditions. They are also great for beginning any CCTV system because they are low-cost and offer adaptability to any security environment.
Bullet Security Cameras are small Video Cameras that are shaped like a rifle bullet. These cameras are typically the width of a cigar, but they are shorter. Infrared Bullet Cameras are larger in diameter than standard bullet cameras.
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.Two-way audio via a single network cable allows users to listen to and speak to the subject of the video (e.g. gas station clerk assisting a customer on how to use the pay pumps)
A pan–tilt–zoom camera (PTZ camera) is a camera that is capable of remote directional and zoom control. In television production, PTZ controls are used with professional video cameras in television studios, sporting events, and other spaces. They are commonly referred to as robos, an abbreviation of robotic camera.
Pan-tilt-zoom (PTZ) is a name given to a type of IP camera where the user can control the movement and position of the lens from a remote location using controls on an Internet browser or software application.
Speed Dome Camera is a device capable of image exposures in excess of 1/1,000 or frame rates in excess of 250 frames per second. It is used for recording fast-moving objects as a photographic image(s) onto a storage medium. After recording, the images stored on the medium can be played back in slow-motion. Early high-speed cameras used film to record the high-speed events, but today high-speed cameras are entirely electronic using either a charge-coupled device (CCD) or a CMOS active pixel sensor, recording typically over 1,000 frames per second into DRAM and playing images back slowly to study the motion for scientific study of transient phenomena
(Digital Video Recorder) A security system device that records the video from up to 16 surveillance cameras on a hard disk. The frame rate can be switched from real time to time lapse in order to save disk space. Digital recorders are more flexible than earlier analog VHS tape systems, and the video can be easily transmitted over a computer network. A digital video recorder (DVR) is an electronic device that records video in a digital format to a disk drive, USB flash drive, SD memory card, SSD or other local or networked mass storage device.
A network video recorder (NVR) is a software program that records video in a digital format to a disk drive, USB flash drive, SD memory card or other mass storage device. An NVR contains no dedicated video capture hardware.
Video on a DVR is encoded and processed at the DVR, while video on an NVR is encoded and processed at the camera, then streamed to the NVR for storage or remote viewing. Hybrid NVR/DVR security systems exist which incorporate functions of both NVR and DVR.

Video door-phone (also known as video door entry or video intercom) is a stand-alone intercom system used to manage calls made at the entrance to a building (residential complex, detached family home, workplace, etc.) with access controlled by audiovisual communication between the inside and outside.
When a visitor presses one of the outdoor panel pushbuttons, the built-in camera is connected and the image captured outdoors appears on the monitor screen. Connection takes place automatically with no need to activate the equipment, which is one of the essential elements of video door entry.
A smart lock is an electromechanical lock which is designed to perform locking and unlocking operations on a door when it receives such instructions from an authorized device using a wireless protocol and a cryptographic key to execute the authorization process.
Smart locks, like the traditional locks, need two main parts to work. The lock and the key. Smart locks allow users to grant access to a third party by the means of a virtual key. This key can be sent to the recipient smartphone over standard messaging protocols such as e-mail or SMS.
