3 Types of DVR Systems for Recording Security Footage

March 17th, 2021



Surveillance in Houston, TX is very common in this age. In order to archive video footage recorded by surveillance cameras, it is very reliable to use Digital Video Recorders. Basically, a Digital Video Recorder is an electronic device that is used to record videos in digital format to a mass storage device. The basic components of a DVR include software, storage units and a computer hard disk that is all fused into a single unit that is capable of recording and storing video feed and converting them to digital data. These advanced technological devices have the ability to start recording based on the slightest movement through the use of motion detectors.

Since DVRs are associated with surveillance and security cameras, they are designed and developed in different sizes and for different security applications based on the user's requirement. A DVR may be small and may be easily concealable when dealing with a small surveillance camera or in some cases, they may be as large as a television device. DVRs also come with remote controls sometimes which enable a user to watch the footage over the internet from a different place other than in Houston. Basically, there are 3 different types of DVRs. These are as follows:

PC-Based DVR

Normally, a PC based DVR can be integrated into a fully loaded surveillance station. The station will have hardware as well as software compressions which will run on a personal computer. A PC based DVR will consist of a video board, a network card, memory drive as well as a motherboard. They also come with a DVR capture card which will have the necessary requirements like video inputs or Ethernet ports for analog security cameras or IP-cameras.

The main advantage of PC-based DVRs is the fact that they do not have any limitations when speaking about storage spaces. The space involved with these recorders are expandable and flexible so that additional peripheral storage devices can be linked to it.

Analog signals are converted to digital signals and then compressed so that they can be stored in the storage space and then used for further processing. The system allows the search and retrieval of images and videos recorded at any instant of time.

Embedded DVR

In such systems, the device works as a solitary unit and can record analog CCTV footage and store it in hard drives and other external storage devices. The basic software required to run the system as well as additional software is stored on the chip images and videos are stored in a hard drive. These type of systems usually have multiple internal memory spaces and ports that allow connection of other peripheral storage devices.

The system uses a real-time embedded operating system that isn't accessible by an external environment. This makes the system more secure and safe from viruses and malware.

Hybrid DVR

The uniqueness of this type of DVR is its ability to record multiple formats of video like analog CCTV footage and IP camera footage. It allows very smooth transition from analog to IP surveillance. However, the major disadvantage in this type of DVR is the lack of flexibility when compared to other types of DVRs. Because of its ability to accept more than one format of video, it doesn't have any video recording restrictions. This being said it is usually recommended to use analog recording in low-risk areas and IP camera to get high resolution when dealing with high-risk security areas. It is also very easy to manage the recorded analog or IP video data.

Conclusion

Security needs differ based on the different institutions in Houston, TX as well as different security needs. It is wise to consider all the requirements before investing in a DVR. In terms of efficiency, all DVRS are highly efficient based on the security needs. However, it is highly recommended to consult a professional Security Provider in Houston to get the most efficient DVR for your video recording and security needs.

"Steve I just wanted to thank you and your partner Ray Kindsfather for the fine work you men did installing the security cameras around my home. The quality of the pictures is excellent, the clarity in day or infrared mode is exactly what I was looking for. What good is a camera if you can't identify the person and these cameras will greatly assist the police in identifying a perpetrator. The computer side of the job is easy and fast with very little adjustment time for me in finding what I want to see. Software and hardware get A+++++ no doubt about. The Ring is equally easy to use and the quality of the camera is equally strong. The installation was clean and fast. You maintain a clean site, it’s like you were never here. You answered all my questions with pin point accuracy. Integrity suits you well. Your answers were honest and to the point. Refreshing in today’s world. All and all you and Ray make a strong team at DWS Technology LLC. I have no problem recommending you to friend or family, home or business. God bless you both with your business. I will call you for future installations. "

"Ray, in reviewing several different security cameras there were many good products, but none met my criteria of clarity and no long-term contract. Raymond, you showed me one product that caught my attention with the clarity and distance viewing that I could not get with other systems. The zoom after a few feet became distorted with the other systems but with the Alibi NVR package you demoed, we could zoom in and out with clarity which made this product stand out from all the rest. The NVR system is so simple, in fact, anyone can configure the system to suit their needs. You can monitor your home from your smartphone or tablet and having security cameras makes it a great deterrent for criminal activity. DWS Technology delivered as promised! Your installation crew worked clean and treated my home as if it was their own. Great attention to detail! I will recommend DWS Technology to anyone! Great job guys!"
