Product Description


The SPECO DVR-X4K/1 4-camera 40 GB Digital Video Recorder with 4 Dome Cameras combines a cost effective DVR that can store hours of video on a HDD (hard disk drive) without image degradation or tape-swapping, making it an ideal replacement for aging time-lapse VCRs, with four high-quality dome cameras. Easy to set-up and operate, the DVR-X4K/1 allows activity detection and multiple recording modes, making it suited to small- to medium-sized observation systems involving round-the-clock security surveillance.

The SPECO DVR-X4K/1's DVR utilizes MJPEG compression with four recording modes and selectable quality levels that allow a maximum recording resolution of 720 x 240 effective pixels. This unit comes with an internal 40 GB HDD (hard disk drive), and allows event searching by date, time, and alarm. The DVR-X4K/1 features a watch-dog function that returns the DVR to any pre-power-outage stage, and recording continuously or by alarm, schedule or activity detection. The SPECO DVR-X4K/1 includes four BNC (Bayonet Neill-Concelman) composite video inputs, with two BNC composite video outputs for connecting to monitors or additional DVRs, as well as four alarm inputs and one alarm output for connecting external devices. The DVR-X4K/1 is compatible with both the NTSC and PAL TV system formats, and runs on 12-volts of DC power via an included adapter.

The SPECO DVR-X4K/1's four included cameras are SPECO's CVC-645DC dome cameras which utilize 0.25-inch color CCD (charge-coupled device) sensors with 3.6-millimeter wide-angle lenses, and provide 512-by-492 effective pixels. The CVC-645DC has a high resolution of 420 horizontal TVL (TV lines), is sensitive to light with a minimum illumination of one Lux, and achieves a S/N (signal-to-noise) ratio of 48 dB or better. The SPECO CVC-645DC uses the NTSC color TV scanning system, and includes a standard RCA video output with a BNC (Bayonet Neill-Concelman) adapter. This unit runs on 12-volts DC power, and can operate in temperatures ranging from 14 to 122 degrees Fahrenheit. The CVC-645DC comes complete with a built-in automatic electronic shutter with speeds ranging from 1/60 to 1/100,000 of a second.

For ongoing surveillance or monitoring systems requiring video storage and retrieval, the SPECO DVR-X4K/1 deserves serious consideration. As an easy-to-use yet complete security surveillance system, the DVR-X4K/1 operates as a stand-alone unit that is not dependant-upon, or susceptible to the same security risks as, a PC or laptop security system. Users should note that the CCD image sensors in the cameras may become permanently damaged if exposed to long hours of direct sunlight or halogen light, so the cameras should not be mounted or pointed directly at the sun or other bright-light sources.

About Digital Video Recorders
A Digital Video Recorder (DVR) takes video signals from security cameras and converts the video stream into a digital format for storage on an internal hard drive. A DVR also provides a user interface to remotely manage many functions of the video files and cameras, including motion detection and pan/tilt/zoom features. At a minimum, a DVR should allow multiple users to view multiple cameras remotely. Effective video compression is one of the most important considerations when looking at DVRs. The most common video compression formats used in video surveillance are M-JPEG and MPEG-4. While proprietary compression technologies may provide superior quality, their lack of compatibility with Windows-based operating systems may become an issue for archival purposes. Issues of frame rate, resolution, disk size, motion detection, compression ratio, and camera noise all affect the storage capacity of a video surveillance system. High resolution is ideal to capture details, while high frame rates are needed to capture events. Frame rates of less than 20 fps tend to be jerky, while rates of 20 - 30 fps can be adequate for most surveillance needs.
