Before purchasing an NVR, it is recommended to check the manufacturer’s documentation to ensure that it supports the ONVIF protocol.

Can Connect direct to network

The Unifi G4 Pro is an IP-based security camera that can connect directly to an existing internet network. It does not require an NVR for basic functionality.

When the camera is connected to a network, it can be accessed and controlled using a web browser or a mobile app. The camera can also be configured to store video footage on a local server or on a network-attached storage (NAS) device.

However, if you want to store footage from multiple cameras and have advanced features such as human and vehicle motion detection, alerts, and remote access, it is recommended to use an NVR or a video management software (VMS) system. The NVR or VMS can help manage and monitor multiple cameras from a central location, and can also provide advanced features such as video analytics and integration with other security systems. See also Eufy floodlight cameras that come with local memory.

In summary, the Unifi G4 Pro can connect directly to an existing network without an NVR, but an NVR or VMS system can provide additional features and centralized management for multiple cameras.

Let’s compare this premium Unifi G4 Pro camera with similar products offered by Lorex and Amcrest.

Let’s examine the specifications of three different outdoor security cameras: the Lorex W881AAD-E (see also Reolink vs Lorex 4k camera that discussed this product), the Amcrest IP8M-VT2879EW-AI, and the Unifi G4 Pro. To facilitate this comparison, we can refer to two tables. Table 1 provides a comparison of the specifications of the Unifi G4 Pro and the Lorex camera, while Table 2 compares the Unifi G4 Pro to the Amcrest camera.

In the case of the three cameras being compared, the Unifi G4 Pro has the highest resolution at 4K @24 fps, which may be preferable for users who require a high level of detail and smoothness in their footage. However, the difference in frame rate between the cameras is relatively small and may not be noticeable in all situations. Other factors such as price, features, and overall image quality should also be taken into consideration when comparing these cameras.

Optical Zoom

While both Unifi G4 Pro and Amcrest cameras offer optical motorized zoom with a varifocal lens, Lorex cameras do not provide this feature. Optical zoom is generally considered superior to digital zoom as it utilizes a mechanical optic for much better zoom capabilities.

Night vision

All three products are capable of providing color night vision in ambient lighting conditions. However, in low light or complete darkness, they will switch to black and white night vision using IR LEDs. Additionally, all cameras feature an IR Cut filter to improve image quality in varying lighting conditions.

The Day/Night filter is a type of filter used in digital cameras, including security cameras, to improve image quality in different lighting conditions. It works by blocking infrared light during the day and allowing it to pass through at night, resulting in clearer and more detailed images in low-light conditions.

Smart Features

All three products offer human and vehicle detection, which reduces false alarms compared to standard motion detection. Lorex also provides animal and package detection, whereas Amcrest offers more advanced smart features through its AI-based capabilities, including Face Detection, IVS features including tripwire, intrusion, vehicle/human detection, and smart motion detection.
