It works well. Easy to set up. Easy to use. This is the second one I have owned and would recomend.

The most important thing to share is that I received prompt and understandable responses to my inquiries with Tigersecu. This gives a person the confidence to explore unfamiliar tech territory. When I provided the make and model of my existing cameras, they were able to quickly verify compatibility. The biggest delay in troubleshooting a problem is due to email communication. It appears that Tigersecu tries to reply to an incoming email within a day, which I find satisfactory. So, you can't solve a problem with a single phone call, but they are very responsive and provide relevant troubleshooting questions.I experienced two problems with the product that Tigersecu helped solve. First, they helped me identify that my initial "no video" problem was actually a problem with my own associated equipment (when they suggest upgrading the camera power supply, do it). Two weeks later they helped me identify a second "no video" problem as a problem with their product. After a reasonable period of troubleshooting (via email exchange, sometimes including pictures to help guide me), they had me return the product, evaluated it, determined it was faulty, and then shipped me a replacement. Took a little less than a month to go from my initial "Dear Tigersecu, I have no video, please help." to receiving a replacement DVR. I was pleasantly surprised at the helpfulness of Tigersecu's support and extremely pleased by how they stood behind their warranty. Prompt and seemingly competent technical support is my number one reason why Tigersecu will be the first seller I look to in upgrading my system or installing a system elsewhere.The DVR itself seems fine. Has the capabilities I would expect, including receiving AHD and IP video feeds. Setup is easy. The user interface software is fairly intuitive and offers some customization. Wish the DVR had the ability to have a keyboard input. "Typing" through mouse clicks on a keyboard is very cumbersome, but after setup is complete, I wouldn't expect to have to do much more typing. My biggest setup struggle was properly setting the time. I found that I needed to enter the correct time relative to the correct time zone, which meant actually setting a different hour and allowing the time zone setting to automatically adjust to the correct hour. I don't see the need for time zone settings on a DVR. It's not like I will be regularly taking the DVR on trips around the earth. I have the DVR set up as a standalone system, so I have no experience with how well it works to view video over a LAN or over the internet. I desired to see the four video feeds in a certain arrangement on the screen. This required a little trial and error connecting cables to the back of the DVR. I wish the software allowed me to rearrange the channel layout, but it's not a big deal with only four channels. If you had an eight-channel or more, arranging your channel screen layout would probably be a real nuisance.

Ease of setup, technical support, and use.

I recently purchased this DVR to replace an older model. The setup for this was somewhat complicated but after about 30 minutes we we up and running. Everything was running correct when for an unknown reason I lost access to the on screen menu. I called the Customer Service Number and was unable to get through to a Tech. after a couple attempts I sent an email explaining I could not get through to Tech Support, a couple minutes after sending the email I was contacted by a young lady, May who collected the info on my DVR and told me she would have a tech remote enter the DVR and see if it could be fixed. Shortly thereafter the DVR was fixed and running properly. A couple days later May contacted me by email to followup and make sure everything was still operating properly. Good Customer Service is hard to find but it still lives in the Tigersecu Company. 5 Stars!!

I purchased 2 of these units and they came in today. Got one of them hooked up well pleased. The pictures are good with good color and clear. I am 85 years old and some of this kind of stuff has passed me by. Tech. Support was very helpful and they very easy to work with. 5 * for them It has been up and running for about 3 hours now and recorders on motion very well. The program is easy to follow playback etc. works good. I purchased another system last week and that was the sorriest thing I ever. The program was not user friendly, but this Tiger is easy and down to earth to follow and view. I will hook up the other 4 cameras here in a day or so that system is okay, but I'll swap it out with the other Tigersecu I purchased. Hasn't been dark since I got this working, but I feel the night vision will be good too.
