    Mobile DVR FAQ - vehicle application

    Here are some examples for your reference:

    1. Taxi and Personal Car:

    Since taxi cabs and sedans (personal cars) are often small in size, a 2ch mobile DVR or 4ch Mobile DVR will do. For instance, if you only want to capture both the front and back of the car, a 2 Ch mobile DVR camera plus 1 rear camera would be good enough.

    If somehow you want to cover the blind spots, a 4ch mobile DVR with 2 side cameras and 1 rear camera is perfect for you.

    1. Buses and Public Transportation:

    For a transport vehicle with more than 20 seats, you can get a 4 or 8 channel HDD mobile DVR. These vehicles can also use 4ch SSD Mobile DVR. If you like bigger storage, pick an HDD mobile DVR that has 2TB to 4TB (optional) storage. If the vehicle is only used once in a while, a 2ch or 4ch SD card Mobile DVR is enough.

    After you’ve decided on the ideal Mobile DVR for you, you’ll need to decide how many cameras you want to install. Interior cameras are essential for public transportation since they catch the activity inside the vehicle and provide evidence if there is an assault or misconduct inside the vehicle.

    1. Oil tank and Cargo Trucks:

    Because these trucks are so enormous, they have a lot of blind spots. To avoid mishaps, it is vital to catch as many sides as feasible. Putting a 4ch or 8ch HDD Mobile DVR is advised, as is installing 4 to 8 cameras for complete coverage surrounding the vehicle.

    Consider placing an anti-explosive camera on the oil truck and other highly combustible vehicles. It will be an excellent investment because it is fire and explosion-resistant.

    1. School Bus:

    Assuming a school bus is big enough to carry 20 passengers and up, an 8ch HDD Mobile DVR system is advisable. The system can include an 8 Channel HDD Mobile DVR, a people counting sensor, an RFID machine, several vehicle cameras, an LCD monitor, etc. depending on the vehicle requirement.

    What are H.264 and H.265 in Mobile DVR, and which one is better?

    Mobile DVR FAQ - H264 x H265

    When looking for monitoring security devices or Mobile DVRs, you’ll very certainly come across H.264 mobile DVR and H.265 specifications. What exactly do those phrases mean? Many individuals may identify H.264 with a surveillance camera system.

    Many Mobile DVRs or DVR Mobile in the industry have H264 or H265 written on the box or displayed during the first installation of the device. However, many of the better-quality videos that are broadcast online use H.265 compression.

    H.265 is the latest video compression technology that outperforms H.264. In comparison to H.264, H.264 provides superior bit compression of 57 percent at 1080p and 64 percent at UHD or 4K. Because all of our gadgets, from smartphones to smart TVs, are capturing or showing at considerably greater resolutions, HEVC compression is rather critical.

    H.265 provides approximately twice the compression algorithms ratio at the very same degree of image quality or significantly better video resolution at the same frame rate. It enables resolutions of up to 8192 by 4320, including 8K Ultra HD resolutions.

    The present H.264 (MPEG-4/AVC) specification no longer satisfies the demand of video encoding for increased image resolution due to the rapid development of IP video surveillance technologies. The next wave 4K Ultra HD and 8K Ultra HD video equipment will undoubtedly become the industry mainstream.

Because it is considered to be Live Video filming, this is the highest filming rate customers can get from any Mobile DVR. An image is the greatest way to explain a frame.

    What to look for when buying a Mobile DVR?

    Mobile DVR FAQ - things to consider

    Because it regulates whatever your vehicle security system does, selecting the appropriate Mobile Digital Video Recorders is just as crucial as selecting sensors when searching for a Mobile DVR. Nevertheless, because of the variety of options available in the industry, this can frequently appear overwhelming. This is exacerbated further by various firms defining major characteristics in distinctive ways. Breaking it further, these are the factors to evaluate when considering models:

    Channels – The number of cameras that the Mobile DVR may film at the same moment. Most Mobile DVRs typically include four, eight, or sixteen video feeds. Please remember that audio connections are distinct, and some entry-level mobile digital recorders would only accept audio from either of the sensors.

    Frame Rate – A 25FPS Mobile DVR is required for seamless videos with no jumpiness. Sadly, this is where things become complicated. For the finest performance, use a Mobile DVR that can record 25FPS per camera or channel at high resolution. This is due to the fact that some lower-priced devices promise a rapid FPS, and it will actually be at 50% the total resolution, not in full HD. When purchasing a Mobile Digital Video Recorders, ensure that the FPS is steady at the finest parameters. The descriptor “Real-Time HD” should also confirm this. The FPS of a mobile digital recorder is frequently reported as a total figure for all feeds, therefore an 8-channel mobile digital recorder will be represented as 200FPS.

    Resolution – The majority of Mobile digital recorders in the industry feature a high-resolution option, which records 720×576 pixels. Furthermore, some modern mobile digital video recorders that operate with Internet-Protocol Cameras will record in HD which is called 1080P Mobile DVR.

    Online Connectivity – Most Mobile Digital Video Recorders now include an internet connection, enabling users to watch recordings from sensors through the web or on any smartphone. Yet, there is a wide range of interoperability for these functionalities. Some, for instance, allow users to manage the DVR Mobile remotely, while others merely enable users to view a live stream. Also, depending on how you wish to view it on any device, the accessible functionality may vary. Definitely confirm ahead of time how well the mobile digital recorder will interact with your unique device.

    Hard Drive Size – Because all Mobile Digital Video Recorders record video to a constructed HDD, make absolutely certain the one you purchase is large sufficient for your purposes. Some Mobile DVRs also have an SD card slot for additional recording space.

    Extra Functions – Many mobile digital recorders will include extra functions that may be useful in your vehicle installation. Features include HDMI outlet for Full HD monitoring, warning inputs and outputs, GPS, AI-Based system, and room to accommodate numerous Storage Devices. These aren’t normally headline features, but they’re worth keeping an eye out for when evaluating brands.
