CCTV Camera World is proud to provide the future of home and business security - network-based security systems that use a network video recorder (NVR). An NVR is a specialized computer that records security video surveillance footage in digital format to a hard drive. Because the NVR does not have video capture capability, video is typically processed and encoded from the surveillance IP or CCTV camera and transferred to the NVR for storage via ethernet or WiFi network. NVRs are typically employed within IP video surveillance systems.

As experts in the field, we at CAM Security Surveillance LLC have written down pointers that can help you determine the quality of a network video recorder.


Resolution is an important factor to consider when choosing a network video recorder (NVR), as it determines the clarity and detail of the recorded video. Higher resolution can provide a clearer and more detailed image, making it easier to identify people and objects in the footage. In general, it is recommended to choose an NVR with the highest resolution possible within your budget. This will ensure that the recorded video is of the best possible quality and can be used effectively for various purposes, such as surveillance, security, and evidence gathering. Analog high definition (HD) and Full HD are both types of NVRs that are used for surveillance. Full HD NVRs are capable of capturing footage at a higher resolution than analog HD NVRs. Full HD NVRs are able to capture more detail in the footage than analog HD NVRs.

Field of view

The field of view in an NVR refers to the amount of the environment that is captured by the camera’s lens. A wider field of view allows the camera to capture a larger area, while a narrower field of view captures a smaller area but with greater detail. The field of view is important because it determines how much of the environment the camera can capture and how much detail will be visible in the resulting footage. In some cases, a wide field of view is more important as it allows the camera to capture more of the environment, which can be helpful for identifying people or objects that may be out of the frame of a camera with a narrower field of view. On the other hand, a narrow field of view can be more useful as it allows the camera to capture more detail, which can be helpful for identifying people or objects more clearly.

IR distance

Infrared (IR) distance is an important consideration when choosing an NVR camera for surveillance. IR distance refers to the maximum distance at which the camera’s IR illuminators are able to provide sufficient illumination to capture clear video footage in low light or darkness.

IR distance is important because it determines how far the camera can see in low-light conditions. If the IR distance is too short, the camera will not be able to capture clear footage at night or in other low-light conditions. On the other hand, if the IR distance is too long, the camera may be unable to capture sufficient detail in the footage. When selecting a camera for a surveillance system, it is important to choose a camera with an IR distance that is appropriate for the specific needs of the location where it will be installed.


The lens of an NVR camera is an important component because it determines the field of view and the amount of detail that can be captured in the footage. The lens is responsible for focusing light onto the camera’s image sensor and can be adjusted to capture a wider or narrower field of view. A higher-quality lens will be able to capture more detail, resulting in higher-resolution footage. This is important for applications where clear, detailed footage is necessary, such as for identifying people or objects in surveillance footage. In general, it is important to choose a camera with a lens that is appropriate for the specific needs of the location where it will be installed. Factors to consider when selecting a lens include the field of view, resolution, and the amount of ambient light in the environment.


The brand of an NVR can be an important consideration when choosing a surveillance system. A reputable brand is likely to offer higher quality products that are more reliable and have better performance than less well-known brands. There are several factors that can affect the quality of an NVR, including the quality of the hardware, the user interface, and the customer support provided by the manufacturer. A reputable brand is likely to use high-quality components and offer a user-friendly interface, which can make it easier to set up and operate the NVR. In addition, a reputable brand is likely to offer good customer support, which can be important if you have questions or need help with your NVR. In general, it is a good idea to research and compare different brands and models before making a decision. This will help you to choose an NVR that meets your specific needs and budget. As a general rule, any brands that the customer can actually get themselves usually are lower quality products, as the high-quality ones usually need a distributor to get access to them.

Casing for the product

The casing of a network video recorder (NVR) is an important consideration because it helps to protect the internal components of the NVR and ensure that it performs properly. The casing also plays a role in the overall appearance of the NVR, as well as its durability and lifespan. The material used to make the casing can affect the durability and lifespan of the NVR. Materials such as metal or high-quality plastic are generally more durable than cheaper materials. In general, it is important to choose a product casing that is durable, well-ventilated, and suitable for the specific environment in which the NVR will be installed. Before signing for a product, ask to see it in person. Additionally, ensure that it has a minimum of three years warranty.
