What is DVR and CCTV Systems?

Executive Summary about : Cameras Security By  Jason Pachiato

DVR(digital video recorder) also known as a personal video recorder records directly to a disk or hard drive instead of to a video tape of sorts. CCTV security system organizations also use DVR in their surveillance systems since DVR is able to record for extended lengths of time. DVR is therefore used by banks, car dealerships, retail stores, and especially at mini-markets which are a prime target for crime. Such recorder systems are helping combat crime by providing excellent images of people committing crimes.

A typical DVR surveillance system has the essential components including motion sensors, multiplexer, image zoom controls; color quad processor and CCTV camera connections.

Most of such surveillance systems have image zoom controls that can move and turn from side to side ensuring that you don’t have to put more than two cameras in a room. Every motion in the DVR systems can be separated into an image in common formats like jpeg which makes recognition of faces or movements easier.

You can then store the videos according to time and date for sequential retrieving. Some of these systems also offer audio recorders to listen to conversations taking place in a room being monitored. In the near future, more of such technological enhancements will make the DVR security systems even more effective and with possible lower prices.

There are many different types of hidden cameras you might consider if you want to put up surveillance in your home, office, or workplace. These different types include motion detectors, timed cameras, sound activated, nanny cams, and more.

The motion detector cameras are excellent hidden cameras because they use less energy. They require fewer batteries and are the most cost effective camera you can purchase. The camera will activate when it detects movement and immediately begin recording.

These types of cameras will record the video to things like SD cards or send it out directly to a monitor screen. This is commonly used for video surveillance for security guards and other job types. Some people like to put the motion detector cameras outside if they suspect someone is messing with their car in a specific parking space and they don’t know who it is.

Many of the motion detection or other hidden cameras are timed. The timed cameras will begin recording by you turning on the device. They will record for a set amount of time and then stop. Nanny cams and other hidden cameras come in a large variety of shapes and sizes. They are great because they usually come in a format of a stuffed animal, alarm clock, wall clock, book, or some other thing that has a hidden camera inside of it and you cannot see it no matter how hard you look.

These cameras blend in well with the environment. You can purchase a hidden camera in the form of a book and place it in the bookshelf with the rest of your collection. When you purchase hidden cameras for your surveillance purposes there are many for you to choose from. You may decide to get a motion detection camera or even a timed camera. Some cameras look like stuffed animals or a pack of cigarettes and are designed to blend in with the environment while they record hours of video.
