5.0 out of 5 stars Excellent functionality for the price! Great unit!, July 7, 2009

This review is from: New 4 Channel Embedded Linux US411Z-WS D1 H.264 Network DVR With NO Hard Drive, Real time True Triplex with built web server for remote viewing and operation, backup and operation 4CH DVR 480FPS SATA ready (Electronics)

I've had this unit for a few weeks, and I've been experimenting with camera positions and lighting. This Security DVR has worked perfectly.
All features work, as advertised, and are well implemented.

PROS:
-Motion detection with pre-record (pre-time stamps motion event) works great. I really like the function which allows you to fast forward at 32x, and the unit slows right down to 1x right before a car or person walks on my property, then resumes FF when it leaves the frame. I can spend 20 minutes after work, and see every person or vehicle that has entered my property for the past 9 hours I've been at work. Very cool!
-I can access the unit from any computer in my house. The software included allows access to the DVR menu functions as well. Streaming video over my LAN has been glitch free and solid full motion. I haven't tried accessing the box away from home yet. I will update my review if there are any problems with that. (I doubt there will be. The firmware and software have been well de-bugged, for the most part)
CONS:
I only have a couple of gripes about the unit:
-The menu is a little hard to understand, and you have to experiment with certain menu functions to discover what they actually do.(This is obviously a translation issue.) Once you have figured out what does what,
the menu settings are easy to use, and well implemented.
-The compression used by the unit does degrade the resolution a bit, when streaming or recording. Not by much though. The streaming video has very little degradation, and the recorded video is a little worse, with some slight pixelation on the "Best" setting. I understand that this is a compromise between picture quality and disk space, however, I wish it had a better resolution recording option. Large disk drives are relatively cheap anyway. This may become an issue if you are trying to identify a face in the distance. We'll see . . .

Overall, I'm extremely pleased with this Security DVR.
It is well built, and does pretty much everything I would want.
It would be nice to have the USB Flash Drive backup on this one,
but you have to move up to a more expensive model to get that functionality.
For the price, this DVR is an absolute BARGAIN! I've seen VERY similar Security DVRs for $180 and up. (sans drive)

I highly recommend this unit.

This review is from: New 4 Channel Embedded Linux US411Z-WS D1 H.264 Network DVR With NO Hard Drive, Real time True Triplex with built web server for remote viewing and operation, backup and operation 4CH DVR 480FPS SATA ready (Electronics)

I have the model that comes with the 250GB HDD and I am very satisfied with the unit. Like some of the reviews I do think that some of the menu functions/options are quite difficult to understand and that you have to play around with them to see what they do. I've had it running for about year with just a few minutes of interruptions and still running good.

I just enter my current IP and I am able to watch my house while at work and keep an eye on my kids when they get home from, or when they don't have, school. I have a dynamic IP so before I leave for work I make check to make sure what is my current IP. My ISP changes my IP every month - sometimes every week so it's not a big deal. It has worked flawlessly so far. I will be replacing the existing HD with 1.5TB HD soon.

5.0 out of 5 stars A REAL BARGAIN, December 2, 2009

Amazon Verified Purchase

This review is from: New 4 Channel Embedded Linux US411Z-WS D1 H.264 Network DVR With NO Hard Drive, Real time True Triplex with built web server for remote viewing and operation, backup and operation 4CH DVR 480FPS SATA ready (Electronics)

I use this DVR as the central point of my home security system. I purchased a 1TB SATA drive from Amazon which was easy to install into the unit. I have 4 security cameras connected to the DVR which can be viewed individually or as a group of four on my LAN. The manufacturer provides software to view or record the DVR data over a LAN onto a computer. The DVR functions as a web server with its own static IP address when connected to your LAN. The DVR (and all cameras) can be accessed over the internet by port forwarding over a router/modem and then setting up a dynamic dns account. Setting up the DVR for viewing/recording over your LAN is easy. Setting up the port forwarding with dynamic dns is more complicated. A web search can provide tips on the best way to do this.

With the 1TB hard drive, I am able to record over 3 weeks of video data, all for a cost of around $250. Truly a great deal. I also own the 561 model which has been running 24/7 for over a year without any problems. The 561 model comes with a remote control which makes programming easier, but the 560 has all the same functionality on the front control panel.
