Features to Consider When Buying

NVR and security camera isolated

A network video recorder (NVR) system is a security camera system where you install cameras in strategic places in your area. NVR system uses either h. 264 or h. 265 compression codec in saving the videos.

Aside from cameras, the other two general components are a recording device (NVR) and a monitoring device (HDTV or Super HD TV).

To understand more about security camera systems, let’s discuss the different features to consider when buying.

Number of Channels

Channels refer to the upgradability of the NVR system in terms of camera installation. A four-channel NVR can only support a maximum of four cameras. On the other hand, eight channels support eight cameras, and so on.

So far, the highest number is 64 to 128 ports. This type is best for large commercial buildings.

What channels should you choose? The answer depends on the area of your house or your business.

You can start with eight-channel NVR. The great thing about NVR is the scalability of the recording device.

The tip is to buy twice the number of planned installations. If you’re installing four cameras, get 8-channel NVR.

Supported Resolution

CCTVThe typical resolution that an NVR supports is 1080p HD. Some can go as high as 4K while others have as low as 720p. Mid-level products can have 960p.

Higher resolution means the superior quality of recorded videos. But, do you need the highest IP camera resolution for your NVR security camera system?

For home security camera systems, a 1080p HD resolution is enough. The security system yields crystal clear videos. You can already see the faces of the persons who come and go out of your home.

The clarity of images also depends on lightings. Thus, make sure your security cameras for home have night vision for low light conditions.

PoE or not PoE NVR System

Power over Ethernet (PoE) is the use of a single network cable where the cameras connect to the NVR and draw electrical power from the same cable.

Many cameras are now PoE types, and NVR security camera systems have PoE ports on them. With this new technology, set up is easier to install and more convenient than with nonPoE.

If your existing set-up is non-PoE, it requires a PoE switch to inject electricity into the network cable. You don’t need to replace your old NVR for this kind of upgrade. Buy the PoE switch, and you can connect to the existing security camera system.

However, you’ll need some network cables to connect the camera to the switch and network video recorder (NVR). You might need a little help from a technician if you aren’t an expert on network cabling.

Storage Capacity

Often, an NVR has a hard drive pre-installed in it. The hard drive is where the network video recorder stores your video.

The default is 1TB capacity. Usually, an NVR security camera system is upgradeable, and an upgrade can go as high as 8TB.

Some NVR doesn’t support hard drive upgrade, and this limitation restricts the number of recorded videos. An alternative is to create an account with a cloud service.

Another option is to continually transfer your video archives to an external hard drive if the system has low storage and doesn’t allow an upgrade.

The storage capacity depends on the number of cameras installed, IP camera resolution, compression rate, and mode of recording. Higher resolution means more massive consumption of storage space. However, with an effective compression rate, the system can maximize the storage.

Motion detection

Motion detection is a standard functionality of home security camera systems. This function saves storage space. This feature is best for home installation. However, simple motion detection without any advanced algorithm can trigger many false alarms.

Here comes the newest technology: advanced motion detection. This capability of an NVR security camera system includes line crossing, and dwell detection mode. These algorithms can minimize false alerts and even save more storage space than standard motion detection.

This kind of advanced detection is best for crowded areas such as business establishments. You can also consider this feature when buying a surveillance system for your home security.

Advanced motion detection is best in alerting you for intruders, especially the dwell motion. Dwell motion sends a command to your system and specifies how long a person has to stay in a particular area. When a person stays more than usual, the NVR system triggers an alarm or notify you about suspicious activities within your premises.

Software Application

An NVR system comes with a software application. This application is where you control the functions of the system.

The best application should be user-friendly with easy to find icons.

If in case the icons of software applications aren’t the same with computer icons, they shouldn’t be too hard to remember.

Compatibility with smart hubs is an excellent bonus, especially if you’re planning to upgrade with intelligent home systems. Seamless integration would be an excellent addition to the features of your NVR system.


Security cameraAn NVR security camera system is either wired, wireless, or wire-free. Often, people misunderstood the difference.

When a security system says wireless, it doesn’t mean wire-free. The system still needs wire for power adapters. The wireless feature refers to the transmission of data from the IP camera to the NVR.

A wire-free system still exists, but it’s not advisable for outdoor home security because you’ll need to change batteries often. Usually, a wire-free security camera system is best as a nanny cam.

So, should you choose wireless or wired? The answer depends on your security needs.

We recommend that you opt for both. Many NVR systems support both wired and wireless options.

Wired option is best for outdoor installation due to a high risk of lost transmission. With a wired NVR security camera system, one hindrance is a power outage for a continuous recording. You can solve this dilemma with backup power.

Remember, obstacles can limit the range of transmission for wireless security systems. Thus, wireless NVR security camera systems are best indoors.


Manufacturers of security camera systems need to include certification of their products. One of these certifications is either IP66 or IP67.

This IP66 certification means the cameras can withstand mild weather conditions. Cameras are weatherproof and waterproof.

What’s the difference? An IP67 camera is also weatherproof and waterproof.

The difference lies in the waterproof feature. IP66 is a waterproof certification to the extent of water splashes, while IP67 can withstand splashes and water immersion to some extent.

If you’re installing an NVR security camera system, just outside your door and in the shade, IP66 certification is enough. However, if you install an IP camera where exposure includes rain and snow, IP67 certification is much better than IP66.

The standard is IP66 certification. Some NVR security cameras may have a lower certification number, so watch out for it.

Don’t purchase anything below the standard if you’re planning to install a home security camera system outdoors.

Night Vision

Night VisionThis feature allows your NVR security camera to record videos and monitor the area with crystal clear reception. Often, cameras with this feature have LED lights built in them.

This feature is already a standard on security camera systems. The difference lies in the quality of recorded clips.

Some cameras even have an infrared vision for dark surroundings, enhancing the recorded clips more than an ordinary night vision capability.

You need this feature if the area of the installed IP camera doesn’t have good lighting. Maybe, you want to ensure and intensify your home security even during the night.

Remember, this feature adds up to the cost of the security camera system. The more powerful this feature is, the higher is the cost.

Audio Support

Some NVR security systems support two-way audio. So, if you want to record audio for your videos, opt for this one.

Most importantly, check if the bundled cameras have a built-in mic. The audio function of the NVR is useless if the cameras don’t have audio recording capabilities.

If the cameras don’t have a built-in mic, you can buy one that has it. But, you have to determine the best place to put an audio-enabled camera.

Field of View

Bundled security cameras with an NVR security camera system often have an average of 90 to 100 degrees. This limited view requires a strategic installation of cameras. Some users install these cameras a few feet from another to cover a whole area that needs monitoring.

Compression Codec

This codec is a software that an NVR uses to store video files in the hard drive. It is either h.264 or h.265. The latest is the h265, where an NVR compresses twice the standard rate of h.264 with the same quality.

With this technology, the NVR can save more storage space. Most systems use one of these two codecs. Some NVR security camera systems support dual compression rates.

We recommend that you choose a single compression rate even if the NVR supports two codecs.

Monitoring Device

MonitoringThis feature is the least of your concern, but it is still vital that NVR can support high definition monitoring device. Why? Because it’s useless to have full HD security cameras if you can’t view videos clearly in a monitor.

This device can either be your Super HD TV or your laptop computer. Most NVR systems can support ultra HD monitoring devices.

External alarm

Another excellent feature for some NVR systems is the capability to connect with an external alarm system. This capability might be a little more expensive. However, a properly configured motion detection is enough to catch intruders into your house.

Advanced Features

Pan, tilt, and zoom (PTZ) are three of the advanced features a security camera can have. However, these types of cameras are pricier than standard cameras. Read our guide on how to choose the best PTZ camera for outdoor home security camera systems.

Wrapping Up

The best NVR security system doesn’t need to have all of the features we mentioned above. Otherwise, having them all is an overkill. Besides, you can’t use all of these features anyway.

So, which features should you include in your purchase?

First, determine the purpose of installing an NVR. For example, you want to catch the intruder because every night, the alarm gets triggered.

With this purpose, you’ll need an NVR with cameras that have a night vision. Advanced motion detection is also helpful to make sure you catch the intruder.

Before the alarm goes off, the NVR system already sends a notification to your phone because you enabled dwell detection. Mobile integration is also an important feature based on our assumed purpose and situation.

If in case you can’t catch the intruder, you’ll want to go over the recorded videos to see who’s trying to break in your house. Thus, a high definition IP camera is a must so that you can watch crystal clear videos.

A 1080p HD resolution is an excellent choice. Higher than this standard might be too much for the purpose, but we aren’t hindering you if you want 4K HD resolution. If you’re going to zoom the clips, you’d want a non-pixelated image to see who’s giving you that sleepless nights.

By the way, never forget about tech support. No matter how knowledgeable you are, you will still need tech support for warranty purposes.

Of course, you can widen the scope. Lastly, make sure your budget is enough for the purchase of the products.


To help you with your decision making, here are some questions that many people ask when buying NVR security camera systems.

What is the best NVR system?

The perfect NVR system should have high-resolution cameras, enough storage capacity, and weatherproof. Your budget is the only limitation of your purchasing power for NVR products.

You can also choose a night vision as part of the features. Alternatively, advanced motion detection is also an excellent addition.

Most importantly, the best one does not break your budget and does not compromise your home security.

Security Camera System

Which is better, NVR security camera system or DVR system?

In terms of scalability and ease of installation, an NVR system is better than DVR. For more details, please refer to our discussions on these topics. The comparison between the two requires a separate article.

How do you select the right NVR security camera system?

Your choice depends on your needs for home security, your budget, and the features you want. The important thing is the NVR security camera system covers critical areas for monitoring.

If your area is prone to intrusion at night, you can include super night vision and external alarm integration as the essential features. Mobile integration is best if you are always away from the location of your NVR or your home.

This integration sends alerts to your phone when triggers meet the set requirements for notifications. Some sophisticated NVR systems even allow sending signals of distress to the proper authority.

However, this kind of notification requires a special arrangement with security agencies. You can ask around if such services are available in your area.

You can use our guide above for more details.

Is an NVR necessary?

Well, yes, if you are afraid of your security. If you think that you are at risk every day, you can install the most sophisticated NVR security set-up in your home.

Nowadays, some businesses need to install a surveillance system. One reason is to intensify the security and safety of their customers. Another reason is the regulatory requirement imposed on them.

For homeowners, it’s entirely a preferential matter and not a mandatory requirement. It’s your discretion whether or not to install NVR for your home.

How many IP security cameras are enough?

The areas covered and the purpose of the NVR security camera system are the two main factors in deciding the number of cameras you need. Are you planning to monitor every exit or entry point in your home or business? Or, are you intending to monitor critical areas such as backyard (for home security purposes), or cashier area (for catching a thief)?

If you do, then the number of entry/exit points should correspond to the number of cameras. Often, a home surveillance system needs a minimum of four cameras. For small businesses, 8 or 16 surveillance cameras are sufficient to cover essential areas.
