Features of the D841
Lorex D841

The new DVR (Digital Video Recorder) Works with analog cameras that transmit high-quality video over regular coaxial or BNC cables, each camera includes a Siamese BNC such as (RG59-RG6) cables that carry power and video. The Lorex DVR will record high-quality images coming from the Lorex BNC cameras and save each recording into internal Hard drive storage.

Besides that, this DVR can receive HEVC (High Video Efficiency Encoding) or H.265 video compression files, this type of encoding will save up to 40% more space when compared to H.264 video compression. This feature works as a video player for the system, which will allow the user to save space on the hard drive because the most common video players like MP4 or AVI will consume more capacity.

That said, the video compression that comes with this system will save space on your hard drive, so you will have more days of playback time.

The Lorex DVR works with incredible smart motion detection, in which the system will be capable to recognize the motion events triggered by a person or a vehicle. This feature will reduce unnecessary alerts and false alarms, making users’ lives easier as you can find important recordings with the smart search feature on the system.

Reliable security-grade hard drive with no hidden storage or cloud fees, which means you don’t need to pay any charge to save your recordings’ such as the D841 is capable to work 24/7 without stopping on the continuous recording mode.

The amount of recording time saved on your Hard Drive will depend on the size of it, the number of cameras you have the quality of the recordings and the recording mode (continuous or motion detection).

I always suggest having a motion detection mode on that way the hard drive can save a lot of playback time, you can also schedule the recording mode it will allow you to manage specific times when the cameras will record either on motion or continuous mode. Besides that, it is possible to manually upgrade the hard drive up to 10TB in size to get more recording time which is one of the best advantages this D841 will provide.

What are the Main Quality Issues?
Lorex D841

Usually, when something is wrong on the Lorex D841 DVR, people think that the issues can be the security system. However, let me tell you that the most common issue of this system is the power supply.

That said, the DVR works with BNC cameras, which means that you need to connect video and power cables on cameras to get the picture. The common issues like a camera with streak lines, not showing pictures or having blurry images can be on a video cable or the power adapter of the cameras. The way to distribute power to the cameras will be with a power splitter which is an accessory that provides power into four or eight cameras at the same time coming from the same power source.adapters

In that case, when a camera is having image or power issues, steps like swapping the power adapter and video cables will be important to determine where the problem is located.

However, on this Blog, we will develop some methods to troubleshoot this kind of situation.

This DVR works with a 4K resolution as default which means a monitor with low resolution will not support the quality of the system this will produce a resolution mismatch taking you to a Lorex Logo and then on a blank screen with a No Signal message, people will be confused at this situation and will think system is not working. However, this issue is just a resolution mismatch easy to solve.

If you have the New D841 System connected to the internet but during the set up on the mobile app is showing Device not found or Failed to connect, the main reason will be the system is not properly connected to the internet or system is not upgraded with the latest firmware version, Lorex Video recorders don’t support signal coming from extenders or bridge connection on the routers.

  1. I just bought this system form the Lorex website. I haven’t gotten a clear answer from them, maybe you can help. At night our cameras that are outdoors are black on our monitor and phones even when we activate the light we still see nothing, they work fine during that day. Suggestions?
