Good, will update w/ further exploration

Amazing picture quality though no imagery at night. Playback feature could be better continues to freeze and lag on the fastest internet connection possible.I would prefer more ease of setup and description of features.

installed at lake house

Enjoying the customisations available. Much to learn. Fairly user friendly with a bit of exploration. Human detection feature is a bit of a challenge yet.

Nice system

The camera install was the hardest part for me. So far the system works great. I like all the features it has and have just started to connect it to the internet.

Smart home features are missing

This is an easy install and works better than other IP security cameras. It would be nice to have the Defender cameras to work with Amazon Alexa, Google Home for smart home features which other camera vendors have it.

just an avearge..

I did not know that it will need a screen to do all the configuration and settings. that is a drawback. Clarity of picture is not as per my expectations. It can't read the number on my car's number plate parked just in front of my driveway.

Hello Rohit, Thank you for your honest review. The system can be monitored from the app, to set the system and for several configuration options, you will want to connect the NVR to a monitor or TV. Please reach out to our support team, we would be happy to assist you with checking your settings to ensure you get true 4K picture quality. Thank you for choosing Defender to protect what matters most. Amanda M. | Defender Customer Experience Expert

Great quality 4k camera system

Bought this system for my garage area and Alley.  I had the last model for my house and was pretty happy with it, great picture, good value, nice iphone app.   This new model has all the things I liked about the last model, but upgraded software on the NVR box.  Its easier to setup, the interface looks sleeker, and setup process was faster.  Most of the time I check the alerts and views on my iphone app, and it can show you all the motion alerts with a nice little link that takes you to the right spot in your recording, from there you can watch, skip back or forward to get more context. I like the look of the cameras, they feel pretty sturdy, and you can set them up to have a security light type response, or go more stealth with just the infrared option.  Setting that up took a bit of poking around in the menu, but now that its setup, I have it setup differently per camera, which is nice.  I like that I can add up to 4 additional cameras if I need later, 4 was enough for my needs now though. I also really like the POE format, power of ethernet, which means one cable sends power and picture/sound signals, no need for extra wires, and you can use most any cat5 type ethernet cable (this comes in handy if you need to setup outlet plates and a few dis-connectable wires).  Another bonus to having this wired system is its harder for thieves to use wireless camera disrupters to block signals. II was already able to get footage right off my phone for a neighbor when someone broke into their adjacent property to send to the police.
