A digital video recorder (DVR), sometimes referred to as a personal video recorder (PVR), is a consumer electronics device or application that converts video to digital format on a hard drive, USB flash drive, SD memory. Record to a card, SSD, or other large computer device. Local or online.

It can record directly to a VCR that can record analog signals in the form of images. If the analog signal is recorded on a tape, the tape must run very slowly for it to run continuously. This is because for a three-hour tape to run for 24 hours, it must be set to run at a time interval that is typically about four frames per second. The camera image may change dramatically within a second.
For example, a person can walk a distance of one meter, so if the distance is divided into four parts, that is, four frames or “shots” at a given time, then each frame always looks like a spot Unless the object is relatively stable. The analog signal can also be converted to digital format so that the recording on a computer can be saved as a digital recording. In this case, the computer’s analog camcorder must be connected directly to the video card, and then the card will convert the analog signal to digital format. These cards are relatively inexpensive, but the resulting digital signals are essentially compressed at a 5: 1 ratio (MPEG compression) to continuously record video.
Wires and cables may not be the brightest part of the security system, but they are an important part of the overall solution. There are many things to consider when researching and installing wires and cables to make your security system work better. At least the cable will be used to power the camera, and most of the cable will also be used to send the camcorder’s signal to the DVR. To determine the appropriate cable for installing a security camera, you must first know whether your system is analog or digital. You then need to know whether the camera will operate locally (within a few feet of the power source) or remotely. If you connect the camera to a remote power source, consider using the power cable and video cable at the same time. Video security cables work alongside power and video cables (known as Siamese cables) or are all available under one sheath. This would make installation much easier than trying to pull two separate wires.for the professional and experienced visit CCTV Camera installation in Dubai today.
