  • Overview

    This compact 4-channel DVR is only about an inch thick, but it delivers the performance you need for your mobile surveillance applications. The versatile unit can be installed under vehicle seats, below the radio compartment or in the trunk. The mobile digital video recorder has 4-channels and records 720 x 480 (D1) resolution at 30 frames per second — on all four video channels.

    The MDVR21SD features H.264 video compression to maximize recording and consume less space on the SD card*. The unit also records in AVI files, which makes video offloading and playback easy as well. This device features 4 alarm inputs, and two alarm outputs for event-triggered recording, such as bus doors opening or closing, activation of signal lights, increased speed, sirens and more.

    The DVR is equipped with a built-in GPS overlay for data, speed, and coordinate location, and a graphical, easy-to-use on screen display (OSD). This compact mobile DVR also features a tamper enclosure that locks over the top of it to prevent unwanted access to the device — for added security.

    Note: The Ethernet port on the front of the DVR is for local access only (not for remote viewing).

    * SD card is not included.

    Key Features

    Easy Offloading and Playback – DVR records in AVI format enabling easy offloading and playback—no conversion required. Simply pull out the SD card, put it back in an SD card reader and open up a Windows media file.

    Record in Separate or Composite Quad Recording Modes – Dual recording modes enable you to choose separate or composite recording to suit your application needs. In separate mode, the device will record a separate video file for each camera, so when you remove the SD card, you’ll have four separate video files (one for each channel). Composite quad recording mode allows you to have one video file with a quad view, which cuts your resolution by a fourth but enables your recording time to go up by 4 times.

    Configurable Video Recording Settings – Enable you to optimize video quality. You can individually select resolution, frame rate and various video quality settings for each of the four channels to optimize video quality and recording storage. For example, you can lower resolution and frame rate to get more recording time.

Nice unit. Documentation is horrible.

Overall

Using this unit to record/control PTZ cameras in a surveillance van. Probably NOT the typical application and I'm using features that most folks won't need, but here-goes...

GPS: Burns in both speed and coords onto video if desired. Syncs time/date to the GPS (nice!). Gets a basic cold fix in about 3 minutes.

Other Burn-in: Aside from speed, coords, time and date, you can show the individual camera ID and two other alpha-numeric fields (company name, license, whatever).

RS-485: It's in the operating system, menus, etc. but for some reason the manufacturer didn't put the required A B wires in the plug so you can actually use it. I stuffed a couple of wires in the correct ports within the correct plug ghetto style. Works a peach.

Cables: The connectors hold well but don't seem really rugged.You really should install some clamps to keep them from getting pulled out.

PTZ Control: Works but is a PITA to learn to use... You have to select the camera to view, then select PTZ control, then select the camera to control while in PTZ mode (PTZ camera doesn't default to the one you're actually viewing). Then if you view a different camera, you've got to change the PTZ camera too or you'll move a camera you're not viewing Once you get used to it it's not that bad but the software could've been made much simpler. Worth Noting.... Unit randomly/momentarily stops sending data when holding UP/DOWN/ZOOM+/etc. on the remote. It's not the remote nor is it the protocol/baud settings. It's the unit''s software. Not a BIG deal and only stops for a fraction of a second, but just enough to drive you batty if you're trying to smoothly pan or tilt.

SD Capacity: I'm using it with a 64gb SDHC card without problems, formatted it using the unit's menu selection. Only works in the SD slot though (unit didn't like my USB SD Card adapter).

External HDD: Recognizes and records to an external 2TB drive again formatted using the unit... Sometimes. Sometimes it doesn't. I think it's just too slow to read the big drive. Works fine with a 256gb drive but the smaller sizes are getting a little tough to find off-the-shelf.

Wireless LAN Access: Can be done. Bought a Wifi bridge off EBAY (same unit shown in the manual). Setup was initially a PITA but once I got it right, I can access the files and stream the individual video channels wirelessly.

Network Access: You can map the unit's active storage device to your OS via SMB protocol. Must include the 'share' directory and trailing backslash like this:
smb://IP_ADDRESS/share/ (Linux)
//IP_ADDRESS/share/ (Windows)

Video Streaming: Video is streamed via RTSP protocol on port 554. You can use VLC Media Player if you have Linux, or if you don't like the ViewPro software (it's buggy). Video streaming works fine over WIFI.... Skips a frame or two at high FPS and bitrate, but still pretty smooth on my little hotspot. I haven't tried setting up my hotspot to forward the video to the interwebs since I don't have any use for that. With VLC, use the following URL for a 'Media Stream':
rtsp://IP_ADDRESS:554/ch01 (or ch02, ch03, ch04).

Theres a feature that APPEARS to be be a video server in the unit's software but I haven't figured out how to use it. VLC has a browser plug-in though and it works fine.

Lockable Case: Horrible design. You can't use an external HDD, thumbdrive or connect a LAN cord with the top of the case installed. But if the top ISN'T installed and locked, the unit will fall out (the unit itself has no mounting tabs). I ended up mounting only the bottom half then wire-tying the unit down to it.

Documentation: Typical Chinenglish. Describes in detail the obvious stuff you already know, entirely skips over the stuff you can't figure out on your own.

ViewPro: Got some nice features and does what it's supposed to do. Change DVR settings, view the streams, PTZ, blah blah. Buggy as all get out though - Randomly loses it's connection with the DVR and doesn't shut down nicely. Only works on windows too. Found it easier to set up the DVR locally, then access the files and video streams through the OS and VLC respectively.

Elsewise: Nice unit. Once it's set up, it does what it's supposed to do very reliably.
