Looking for the best NVR? This guide will help you find the right recorder for you, understand the terminology, and get the recorder at the best price.
NVR stands for Network Video Recorder, a device that serves as the hub of a network security camera system. It serves as the storage and review point for the video surveillance system, so there is no need to subscribe to a remote service to store video.
This means that it usually requires a camera connected via a Power-over-Ethernet (PoE) cable (see our guide to the best PoE cameras (opens in a new tab)) and at least one hard disk.
Retailers often offer NVRs in multiple bundles with different camera types, the number of cameras, and hard disk capacity. Some all-in-one kits are a real bargain; the only drawback is that the product names are confusing.
Best Camera for ZoneMinder
It is an ONVIF IP CAMERA that works with ONVIF-enabled NVRs and third-party video surveillance software such as Blue Iris, Ispy, Security Spy, Zoneminder, and Synology. It also has a slot for a hard disk. It also has a microSD card slot (up to 128 GB, cards sold separately) to store images and video locally for playback anytime, anywhere via a smartphone app, eliminating the need to purchase third-party NVR or video surveillance software.
AUDIO POE CAMERA with built-in microphone and speakers allows you to hear and talk to people in the monitored area in real-time. Since audio can be recorded at the same time as video, security is assured. An audio alarm can be set to alert intruders when motion is detected.

How to Use This IP Camera
Choosing an IP camera is difficult. If you are new to the market, we recommend that you first read IP Camera Basics, a collection of frequently asked questions about IP cameras.
All of the cameras recommended in this article are DIY cameras that do not rely on the cloud or even the Internet. None of them are crippled by manufacturers to charge a monthly fee.
I recommend sticking with one brand for convenience and maximum compatibility, but thanks to the ONVIF and RTSP standards, you can mix and match, as I did with my DIY home security camera setup.
And if you start with one of these cameras, you can always continue to use them in future installations that also support open industry standards like ONVIF and RTSP.
If I am new to DIY, how do I choose an IP camera?
I have created the EasyDIY/ProDIY framework to help you choose the best system for your needs.

Looking to start with one camera to cover it all and then expand with an NVR or NAS NVR? Excellent!!! That’s how I started. Choose a camera with internal storage (SD card slot) from the recommendations below.
Want to start with a NAS as an NVR and feel free to add IP cameras later? Great!!! Any of the recommended cameras below will do. Go to the recommended sites below.
How do I choose which IP cameras are compatible with my existing NVR?
If your existing NVR does not support ONVIF, choose an IP camera of the same brand as your NVR.
If your existing NVR supports ONVIF, any of the recommended cameras below will work.
Advantages of the Best Camera for Zoneminder
Definition of Capabilities
It is helpful to create an entry in the camera capabilities table for each camera model used. To show only those features that are supported by the camera, indicate which features are provided by the camera. Since multiple features may be supported, the entries in this table should reflect the actual functionality of the camera; ZoneMinder includes several examples that can be used “as is” or “with modifications”.
Normally, ZoneMinder cannot be used to send commands to a camera or receive responses from a camera. Scripts defined in the control capability translate action requests from the web interface into a standard set of commands. Many cameras may require a new set of hands. If control commands exist in other applications, the scripts act as a “glue” layer between ZoneMinder and those commands.
The control and capability elements of ZoneMinder are not intended to support all cameras from the outset. Many cameras will require some level of development.
The short event list area turns into a control area when you click on the “Controls” link at the top of the window.
This is when the system is defined as having a controllable monitor. This window will display exactly what you have just specified. Typically, there will be a pan/tilt control area and one or more auxiliary controls such as zoom and focus. If there are predefined media, a section will appear at the bottom of the window. Clicking on the appropriate graphic will send commands to the camera via a control script during monitor control. It may take some time for the camera to respond.
The control arrow will usually respond to where you point it. For cameras with different pan and zoom speeds, placing the cursor near the indicator point will invoke a faster speed. Clicking on the base will bring them together at a slower speed. Clicking between the arrows will stop the current activity. You can use a for pan/tilt control and a for zoom and focus power.
In browsers that support streaming images directly, you can now click on the image itself for certain controls, such as mapped movement. Using this method, you can direct the camera to the part of the image you are interested in. It is also possible to control relative motion by clicking on a portion of the image.
and the direction is determined by the distance from the center. Since it is difficult to determine the direction near the center of the image, the active area begins a short distance from the center. This results in a “blind spot” in the middle of the image.
Check that there is an entry in the capability table of the camera used by ZoneMinder that specifies whether it supports PTZ control. To do so, select “Edit” in the Control Type selection box on the Control tab of the Monitor Setup dialog. A new page will appear with a summary of existing features.
Edit an existing capability by selecting ID or Name, or click the Add button to add a new capability.
Controlling cameras with ZoneMinder requires control scripts or an appropriate application; ZoneMinder comes with sample scripts that can be used as-is or as a basis for further development. Control scripts are executed atomically.
That is, actions from the web interface are executed and no status information is maintained; ZoneMthis. does not understand the status of the camera from a control perspective, so if your protocol requires status information, you must ensure that the script maintains it.
When writing custom control scripts, you must make sure that they are compatible with the settings that ZoneMinder will send.
If you already have a script or application that controls the camera, the ZoneMinder control script will translate the parameters passed to it into a form understood by the existing application. In order to support the activated protocol, the parameters passed in the script must be modified into equivalent protocol commands. You can expect statements that match the control capabilities defined above.
How to Choose an NVR System
Choosing an NVR requires you to think about the core of your security system, and your choice will depend on whether you are starting from scratch or already have cameras to connect. Either way, if you make the right choice, you can add or replace cameras and hard drives for years to come.
One hard drive is enough to store several days’ worth of footage, but two or more will allow you to maximize storage in different RAID configurations or create live backups.
If your NVR has a built-in network switch, you can connect directly to the camera. Otherwise, a separate Ethernet switch is required.
Look for a connection that can power the camera using PoE (Power Over Ethernet).
Cameras from major manufacturers are generally compatible as long as they support the ONVIF standard, but there is no guarantee that AI functions will be supported by software from other manufacturers. There are more reasons to look for bundled products.
While the major manufacturers develop their own software, there are several Linux-based systems that allow companies that are not as enthusiastic to develop their own NVRs.
In the U.S., Lorex, EZVIZ, and HikVision have been banned by the government from purchasing products. This is the first step toward banning some new products (although existing devices remain available). The U.S. government claims that the company is associated with Chinese government surveillance and violates human rights. Regardless of the rationale, if you are building a system, it may be wise to look for brands that are still on store shelves when you want to complete your system.
What camera to use for ZoneMinder?
Axis cameras are a good choice, but they are expensive; Hikvision cameras are of modest quality and reasonably priced. In general, any ONVIF-compliant camera will work with ZoneMinder.
What can ZoneMinder do?
The software allows three modes of operation: monitoring (no recording), recording after motion detection, and constant recording.
How powerful is ZoneMinder?
There are 4 reviews of ZoneMinder. The overall average rating is 2.8 / 5 stars. Overall: Cannot build successfully on RPi3s or FreeBSD, as of the end of Q1. Overall: 2 cameras kill local network wifi.
The wide range of outdoor IP cameras listed above should give you an idea of the freedom and flexibility offered by the Pro-DIY system. Did I miss a camera that should be on this list? We look forward to your comments.
Have a nice day!
