So far this video surveillance unit has far out paced its price. This unit seems to have high quality hardware combined with up to date video technology. Everything need to install this unit is included. But it does have some minor downfalls.Good:1. Great price2. Up to date hardware.3. sensitive motion detection.4. good picture quality both day & night.5. Installation was fairly easy and straight forward. If you can operate a screw gun and can safely run low voltage network cabling, then you can install this unit. The beauty of POE (Power over Ethernet) is that you only have to run a single networking cable from the DVR to the camera. This cable transmits power to the camera and video data back to the DVR.6. great customer service via Facebook Messenger.7. does not require the internet to be functional.Not so good:1. The user interface on the DVR is outdated but functional. Upon further research, most surveillance units run outdated user interface software. My guess is for ease of use and less hardware requirements.2. If you are going to view saved video footage, i highly recommend hooking a monitor & mouse directly to the DVR unit.3. PC, MAC, & Cell phone apps are functional but still need updating.4. If you plan of monitoring DVR unit over the Internet, you will need a healthy Internet connection. I have a 5mb DSL line, and my uploads speeds are painfully slow causing remote software to be mostly unusable.5. Depending on how tech savvy you are, you may find this unit difficult to setup, program, and review video footage. I do not feel this is limited to this particular company but to the home video surveillance segment as a whole.All in, I feel this is a decent unit and well worth the price.

I have installed this system about a year ago. The system has been operating flawlessly since. Unlike other NVR's this NVR records continuously even when set to motion detection. This is OK since 2TB provides about 2 weeks of continuous recording. The manual may not be updated with the exact operations of this system, but since it is a basic system, I was able to explore each feature and get it set to what I want. Best value for the price! In addition, I have received prompt responses to my technical questions and resolved my issue with the AVSS application in a very short period of time. The service team is prompt, professional, courteous and very pleasant to work with in resolving my issue. 2 thumbs up!!Many moons later.... When ZOSI's updated AVSS software was not able to properly play back previously recorded video, ZOSI's customer support and their technical teams work diligently to resolve the issue. The latest update (AVSS_1.7.4) released today, 9/27/21, works like a charm. ZOSI's customer and technical teams were friendly and willing to do what it takes to resolve my issue. Great customer support team.

The fan in this unit is loud on occasion. There are multiple APPs that are supposed to work with it. The best App is the SECU365 which does not have any build in ads. However all of the aps available tend to say it is connecting when off site and it will cycle stating connected the connecting but will need to be stopped and started in some cases multiple times before it will load.Customer Service does not read what is written when you send them messages. I had to take what they gae me and look for additional help from users with the system on You Tube before I could get my system to connect to the application. I then had to figure out how to get the application to work outside of my shop on my own because the tech people tell you they can see your camera but do not give you enough detail on the setup.The instructions that came with the system are also very basic.Installation and basic setup was easy.The alarm settings do not work properly as when I have it setup for motion regardless of the sensitivity it would go off almost like clockwork on my app every hour yet there was no motion. I then turned off the alarm and it kept doing it for two days before I reset my unit to factory settings and did the setup from scratch.Video clarity is good but I have not been able to get any snapshots from the system unless I use my phone and take a picture of the monitor. For me that is almost useless because you lose the quality of the image. The other issue is when you zoom the image really loses its quality. I would like to see a better quality image regardless. System also freezes up during play back on occasion where i have to reboot. There is no power switch so I have to climb up and unplug the power.If you are looking for cheap and not worried too much about decent quality and don't mind poor customer service this is not a bad system. However I would not recommend for any place that deals in retail because it is not something I can easily work with on the fly and when away from my shop I need a more reliable system.UPDATE 8/22/17 on this unit. One of the power cables for this unit went bad. I had to go thru multiple e-mails to get the support team to send me a new one. I get the cord and just a couple weeks later the other cord goes out. To top it off the system does not provide any info or warning that it has not recorded anything for 5 days. I checked and it says that there is no room on the disk. I have the system setup to overwrite when full and it apparently did not do that. I attempted to format the system and it only freed up just under 200 Gigs. It is still not recording anything.I have e-mailed support again asking for a new unit and or a refund so I can buy a better quality product with better support and higher quality product. This is a BUYER BEWARE ITEM. I do not suggest this unit to anyone after the issues I have had. I bought this only 5 months ago. There should not be this many issues with a new product.

Die Bildqualität ist Perfekt, die Stabilität der Kamera ebenfalls, auch die Sichtfläche bei Nacht kann sich sehen lassen, die Auflösung lässt selbst kleine Details noch gut erkennen.Empfehlenswert

Excellent quality, and really well packed. Very happy, especially considering the price

Excellent quality camera for a good price - night vision nice and crisp, would highly recommend
