Digital video recorder (DVR


Digital video recorder (DVR) is a device that records video without videotape to a hard drive-based digital storage medium. The term includes stand-alone set-top boxes and software for personal computers which enables video capture and playback to and from disk. The DVR provides a convenient, if limited, replacement for the multiplexer + VCR combination and provides non-linear access to recorded material usually selected by camera ID, time and date. The consistency of quality of recorded material will in general be higher than that obtained with analogue tape although the actual quality achieved may or may not be better, depending on the compression algorithm and individual configuration.

In general more programmable options for individual video stream recording parameters, (picture resolution, number of frames per second, trigger options, start/stop times etc), are available, but a DVR is only useful where the analogue cameras are all cabled back to the DVR’s location. Competent DVRs now feature UDP (CAT 5) network ports so that the device can be provided with an IP address and thereby become accessible over an Ethernet network. It uses a single IP address to access thousands of cameras without loading your network. It's easy to set up and use.

Time Lapse Recorders




The time lapse recorder is one of the most important components of a surveillance system. Time lapse recorders are highly durable recording machines made to operate 24 hours a day 365 days a year using standard VHS tapes. These professional recorders are made with the finest quality parts and industrial decks. Some of their main features are event reordering, super fast time and date search, time and date generator and real time recording.

Network IP Cameras







Network IP cameras connect to a computer network. They each have respective nodes, or network addresses, and act as video servers on the network. This allows a user to view the video from any computer equipped with a web browser such as Internet Explorer. No special cables are required; network cameras can plug in to any computer jack available on the local network. Surveillance can thus be handled remotely from anywhere in the world, so long as a user knows the IP address of the camera. Numerous protocols are used depending on the make and model of the camera, including TCP/IP, HTTP, and FTP.

Infrared Illuminators








Infrared illuminators are used in areas where light is not sufficient for surveillance. They are generally used with black and white cameras since these cameras have greater sensitivity to infrared light. Color cameras that switch to black and white at night are coupled with IR illuminators for night time surveillance, making them suitable for both day and night viewing. Infrared illuminators use light emitting diodes, or LEDs, to transmit light. A single LED produces only a small amount of light so banks of LED’s are used. These banks can last up to 100,000 hours. LEDs are therefore extremely economical as well as efficient.

Pan Tilt and Zoom Cameras





Pan, tilt, and zoom cameras are some of the most versatile cameras on the market. They can pan (move left and right), tilt (move up and down), and zoom in or out. Additionally, PTZ domes can rotate 360 degrees and view an object directly below them.
A camera’s motion is remotely controlled with a keyboard. Patrol movements can also often be programmed. These allows users to pan, tilt, and zoom into a specific area with just a push of a button. Preset patterns can also be triggered automatically even when the user is not near the keyboard. This is done by connecting devices such as magnetic door contacts, motion detectors, and panic buttons directly to the camera. When a certain device is triggered, the camera can move to look in a predetermined specific location.

Night Vision Security Cameras








Night vision cameras combine a black and white camera with infrared illuminators for night time surveillance. Even if you use color night vision cameras, they will switch to black and white when used with the IR LED’s at night. This is because black and white cameras produce a better image that color cameras in low light levels. Cameras that are able to switch modes are also called day/night cameras. A built-in light sensor determines when light has changed enough for the camera to operate in night mode and prevents the switching of modes due to a cloud or another temporary object. Infrared illuminators can be purchased separately for cameras that do not come equipped with them.

Color Security Cameras


There are numerous camera types on the market and Surveillance Video carries them all for your convenience. Board cameras are small, compact cameras that features a lens directly mounted to a circuit board. They are most often used for discrete applications. Bullet cameras differ mainly in their appearance. Also called lipstick cameras, they are small, cylindrical, and often housed in metal casing. Domes are half spherical shaped cameras that are often used when discrete applications are needed. Fixed cameras are also known as box cameras and often consist of only the camera body; a lens, a power supply, and a bracket must be purchased separately. These cameras are most often what comes to mind when a security camera is thought of. Most of these different camera types come in indoor and outdoor models. Nightvision models are also available that combine the camera with infra-red LED’s for night time capability. With all these choices, it’s common to not be sure about what camera or cameras fit your needs. Simply call 1-800-955-5201 and talk to one of our surveillance specialists. We’re more than happy to help.
