Mobile DVR or Mobile NVR, how to choose?
MOBILE DVR (MDVR, Full name: Mobile Digital Video Recorders) Commonly known as car DVR, it is a device that uses advanced video and audio codec technology to perform digital-to-analog conversion of the video inside and outside the car, and performs compression storage. At the same time, it can perform additional functions such as GPS positioning, audio and video monitoring, and wireless network transmission equipment collectively.
The car hard disk video recorder adopts the high-performance H.264 coding standard, integrates 4G video capture, GPS positioning management and wireless transmission, and integrates 4G wireless communication technology, GPS global satellite positioning technology, and video surveillance technology. It is a new generation of wireless vehicle video surveillance solutions core product. It has powerful audio and video capture, driving data storage and transmission functions, advanced hard disk shockproof, dustproof, and heat dissipation patented technology, all-aluminum heat dissipation design concept, three optional network communication methods, and it is suitable for high-speed sports, severe vibration, unstable power supply, severe interference, dusty and other harsh vehicle Mobile environments, widely used in buses, long-distance buses, taxis, logistics vehicles, private cars, special vehicles (such as cash transport vehicles) and other Mobile environments video surveillance field.
MOBILE NVR (MNVR)，The full name is Mobile Network Video Recorder, which is the on-board network video recorder. It encoders or network cameras to complete video recording, storage and forwarding functions.
NVR has different product forms. Although its core function is the capture, storage, management and forwarding of network video streams, different companies have different designs to complete these functions and have their own characteristics. The MOBILE NVR developed by our company is an embedded NVR product, that is, an embedded device based on an embedded hardware platform and operating system. NVR technology application function mode is more flexible and can meet the functional requirements of today's video surveillance system to a large extent. The solution with NVR technology as the core has the advantages of flexible operation, convenient use, economical and practical, etc. Its front end mainly cooperates with high-definition video cameras to support 8-channel 1080P high-definition video image access, and then realizes centralized management of high-definition video image information through NVR technology and real-time storage. In addition, it can also support the remote management of video images, the preview analysis of video images, and the real-time upload of video image data through the gigabit Ethernet port, local preview, and video recording playback.
1. What are the advantages and disadvantages between MOBILE DVR and MOBILE DVR?
MOBILE DVR surveillance system:
Less expensive than NVR systems
Lower frame rates and lower image quality than NVR systems
Simplicity, easier to set up and operate than NVR systems
Requires extra cables and wires, more complex installation process
Image quality is improving (for systems using HD over Coaxial technology)
Separate power source required
MOBILE NVR surveillance system:
Better image quality
Cost, typically NVR systems are more expensive
More system flexibility
Software can be harder to use
Can be wired or wireless; DVR cannot be wireless
Can be used to identify faces, license plates, etc. due to higher image quality
2. When do you choose MOBILE DVR or MOBILE NVR?
*If you already have and use quality analog cameras, the DVR may make more sense. Don’t completely rule out an NVR if its other benefits appeal to you, as it is possible to add an analog-to-IP converter at each camera. You may also be able to create a hybrid system, where analog cameras are in use at some points and IP cameras at others. Why would you want this mix? Analog cameras may be better in low light environments, while IP cameras provide more clarity and an ability to zoom in on an image.
*If you are installing a brand-new security system, the NVR has obvious benefits. It is easier to put in because it uses Ethernet cable and can be partially wireless. IP cameras used with an NVR just need to be on the same network — they don’t have to be wired to a physical system.
*If you have an analog or partial analog system, each camera or component must have its own power source. This makes for more wires, more installation hassles and increased power usage. IP cameras used with the NVR use power over Ethernet (POE) from the recorder so there’s no need for splitters or sockets close by each camera. IP systems also use much less electricity, saving costs.
*The NVR is newer and still more expensive than a comparable DVR system. As it increases in popularity, prices may come down. In particular, the analog cameras used with a DVR are much less expensive than their IP counterparts.
3. NVR vs DVR, Which is Best for You?
Take our company’s 8 channel MOBILE DVR and NVR as an example:
If you need high-quality graphics, and simple installation , I think the MOBILE NVR will a best choose. If you have been installing MOBILE DVR before and are satisfied with its results as well as wants to save costs, the MOBILE DVR is a good selection.
If you would like to use MOBILE DVR and NVR at the same time, our hybrid series would a good choose. Not only supports analog cameras but also IP cameras, very popular in the market.
