Customer review from the Amazon Vine Program The Q-See QS558 DVR is a quality home or small business security tool that will work well for you if you know its limitations. I have tested and installed numerous CCTV DVRs and found this one has quite a few bells and whistles for the price point. See details below or the PROS/CONS list for more. (See my photos under this product for more info too.)
It is an 8 channel DVR with H.264 video compression. That means it can record up to 8 analog cameras of your choosing, including audio if the camera supports it. The H.264 means clearer video while using less hard drive space versus older video technologies.
The DVR video output is via VGA, BNC, or HDMI. So you should be able to run a cable to wherever you need to for local monitoring purposes.
The menu system is nice and presents a good resolution. It's not as clunky as others I've seen on other brands. It is easy to navigate through the menus and it even has a built-in startup wizard in the software, which I've not seen before on DVRs, in case the included documentation is not enough.
Important features for this DVR are that is can record 30 frame per second (fps) for all 8 channels. That's good, fluid motion video. It also allows numerous video streams at the same time, so viewing it remotely on your iPhone won't cannibalize the main video feed. You can stream/record to different places simultaneously without performance loss. (Google `pentaplex' for more info.)
This DVR also offers motion detection, email alerts for video loss, motion, etc. and multi-user capabilities. You can also run PTZ cameras on it if you wish. Each camera (channel) can be configured for different settings, allowing a fully customizable set up. For example, you may want full D1 resolution at 30fps for street cameras to catch moving vehicles, but half D1 10fps for a side area with little activity.
This DVR is advertised as a universal viewer through software installed on a computer, a web browser, or a smart phone. However, it is not as limitless as it seems. The software can be downloaded and installed on Windows or Mac OS, but the web browser feature is limited. It works on Internet Explorer (IE) 10 and below, but it must install an ActiveX add-on for the IE browser. If you are not an administrator on the computer upon which you're using, this will not install and it will not work.
Additionally, it shows to support Google Chrome and Firefox browsers, but it does not do so natively. You must download third party add-ons from various individuals to use these browsers. I didn't like that part. On the up side though, all administrative features were available in the web browser mode as in the software mode.
I installed the iPhone app and tested it out. Be sure to get the viewer app for the series you have (QT, QS, etc) or it won't work. They have several Q-See viewers, which is a little confusing. Once installed, the app was easy to set up and you can simply swipe left or right to change channels/cameras.
On a side note, I visited the Q-See website to check for firmware updates and it has a good layout with easy to find information and FAQs for the products. The knowledge base was very nice too.
Overall, I'm fairly impressed with the feature set. I do wish they offered better browser support NATIVELY, as well as an option for viewing on a computer where one may not have administrative privileges. But for the price, I would definitely recommend it.
