Electronic Security Systems are used to prevent shoplifting from retail stores, pilferage of books from libraries, or unwanted removal of properties from office buildings.
Security hardware includes:
Closed-circuit television (CCTV), also known as video surveillance, is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors. It differs from broadcast television in that the signal is not openly transmitted, though it may employ point-to-point (P2P), point-to-multipoint (P2MP), or mesh wired or wireless links. Even though almost all video cameras fit this definition, the term is most often applied to those used for surveillance in areas that require additional security or ongoing monitoring (Videotelephony is seldom called "CCTV").

Digital video recorder (DVR)
 |
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.
The term includes set-top boxes (STB) with direct to disk recording, portable media players and TV gateways with recording capability, and digital camcorders.
Personal computers are often connected to video capture devices and used as DVRs; in such cases the application software used to record video is an integral part of the DVR.
Network video recorder (NVR)
A network video recorder (NVR) is a specialized computer system that records video to a disk drive, USB flash drive, memory card, or other mass storage device. An NVR itself contains no cameras, but connects to them through a network, typically as part of an IP video surveillance system. NVRs typically have embedded operating systems.
As a more flexible and serviceable alternative to NVRs, ordinary computers may be equipped with video management software (VMS).
HD-CVI Camera
HD-CVI cameras are a type of analog high definition CCTV security camera (megapixel video over coaxial cabling / HD over coax) that supports up to 1080p video resolution. HD-CVI cameras are a great alternative to traditional analog CCTV and megapixel IP surveillance cameras because of their superior video quality and ability to use RG59 coax cable. CVI cameras are used by professional and DIY installers because they are so affordable and simple to install.
For recording, HDCVI security cameras must be used with a CVI compatible DVR. Please confirm that your DVR is compatible with 1080p CVI cameras before purchasing.
HD-TVI Camera
HD-TVI cameras are a type of analog high definition CCTV security camera (megapixel video over coaxial cabling / HD over coax) that supports up to 1080p video resolution. HD-TVI cameras are a great alternative to traditional analog CCTV and megapixel IP surveillance cameras because of their superior video quality and ability to use RG59 coax cable. TVI cameras are used by professional and DIY installers because they are so affordable and simple to install
For recording, HD-TVI security cameras must be used with a compatible DVR. CCTV Camera Pros supplies hybrid HD-TVI / CCTV DVRs that work with analog CCTV and TVI cameras (720p and 1080p models). These hybrid DVRs allow users to mix and match combinations of both camera types and upgrade existing analog systems over time to high definition. We highly recommend Viewtron hybrid BNC DVRs for use with these cameras.
CVBS Camera
CVBS or Composite Video Blanking and Sync is the conventional analog signal delivered through an analog BNC connector. In English, that basically means a pair of wires can transmit video and power from the camera to the recorder producing video surveillance.
CVBS, which is also sometimes referred to as composite video, is one of the standard cabling systems used for analog video. Many older analog CCTV security cameras are connected using CVBS. These are cheap and easy to install cables and were instrumental in early security camera installations.
CVBS refers to the yellow cable in the RCA system, named for the Radio Corporation of America that invented the system in the 1930s. Along with the white and red cables, which combined provide stereo audio, the RCA system makes it easy for anyone to color-match the cables to the right ports to connect A/V equipment.
AHD Camera
AHD stands for analog high definition. These cameras are named that way because they can use the same RG59 coax cable that traditional analog CCTV cameras use, however, the resolution is full 1080p (1920 x 1080) instead of 704 x 480 (analog D1 CCTV resolution). This makes them a great choice for customers that want to upgrade their existing CCTV system from standard to high definition, especially when using an Viewtron hybrid DVR that works with SD and HD CCTV cameras. Because our iDVR-PRO DVRs can also record full 1080p resolution in real time on all channels, they are also a great choice for use with all HD cameras.
IP Camera
IP cameras from CCTV Camera World are the best security cameras you can buy for your home or business. We specialize in professional equipment featuring high quality image sensors for the best color night vision, and AI based advanced motion-detection technology to reduce false alerts.
Wired IP security cameras such as our PoE cameras are easy to connect to a Network Video recorder to build your own PoE camera system. Standalone Wireless Wi-Fi IP cameras are great for hard to wire locations, and allow recording to an internal microSD card.
Constructed with metal or tough ABS plastic, our cameras are constructed to be weatherproof for worry-free installation for indoor or outdoor use. Select dome cameras also feature vandal-resistant design to prevent tampering.
All of our wired IP cameras and home wireless IP security cameras are accessible wirelessly from a smartphone or tablet using our free mobile app from anywhere in the world where a broadband internet connection is available. Replace your doorbell cameras by using our two-way audio cameras such as Active Deterrence Cameras with HD video quality up to 4K.
