Avalonix 4MP Two-Way Audio WiFi Camera System with NVR

This system features the Avalonix Two-way Audio WiFi cameras, which can connect to WiFi networks, and the Avalonix Premium WiFi NVR. They offer convenience and flexibility in camera placement, as they eliminate the need for a cable run back to a wired NVR. This WiFi security camera system comes with high-definition 2K (4MP) cameras. You can install these cameras up to 250 feet away with an unobstructed line of sight from the included wireless NVR anywhere you have a power outlet. Transmission distances are reduced to 100–150 ft with some obstructions such as drywall, but this is still significantly better than older analog RF-based systems. Choose between 2, 4, or 6 cameras to suit your coverage needs when adding this system to your cart. The best part is that there are no monthly subscriptions or annual fees to use the cameras, monitoring software, or smartphone viewing apps. You own the equipment with no extra charges for using your cameras or the apps and software.

The included 12V DC adapters have a 10-foot power cable, allowing flexible placement away from the camera's mounting location.

Unlike battery-operated cameras that hibernate and wake up when motion is detected, these cameras are on all the time. The cameras connect to the included 12V DC power adaptor in a nearby power outlet and stay powered on to provide uninterrupted video streaming and recording back to the NVR. Video gets streamed from the cameras continuously and recorded on the hard drive inside the NVR. There is no cloud recording, and no internet is needed. Even if you don't have internet, you can use this WiFi bullet camera system as it is a standalone system. All you need is a monitor to watch the video from the NVR.

Be sure to watch the video below for real-world testing of this WiFi camera system. We tested all six cameras in our warehouse, including one placed behind 75 feet of shelving packed with products—yet the video remained perfectly clear and real-time. The test shows how reliable the system is, even in challenging conditions. You'll also see that the NVR WiFi system works completely standalone and doesn’t require an internet connection to operate. For those who want remote access, we also demonstrate how quick and easy it is to connect the system to our mobile app. And with built-in two-way audio, this dependable, professional-grade camera system stands out from the rest. You get all this with no monthly subscription costs.

Standalone system: No internet is required for live view, recording, or playback. Internet is only needed for remote viewing and two-way talk from the phone app.

The outdoor-rated cameras in this WiFi security camera system feature 2K 4MP image sensors, which produce video approximately 1.5 times the size of standard HD 1080p cameras. Their 2.8mm lens produces a wide 90-degree viewing angle, allowing you to see faces up to 40 feet in daylight. For night vision and black-and-white general detail, the cameras have a powerful infrared LED beaming IR up to 100 feet. The high-end components in these WiF cameras ensure a quality image along with lighting compensation technologies like wide dynamic range and backlight compensation.

These wireless security cameras boast a robust IP67 weather resistance rating against dust, rain, and snow and come with a versatile 3-axis mounting bracket for simple installation and indoor or outdoor use. Lastly, the camera's integrated microphone and speaker audio equipment allows for audio recording, audio detection, and two-way communication.

The NVR isn't a slouch either, with a robust WiFi radio and variety of useful features to assist you in becoming a surveillance sleuth. You have the ability to completely customize how and when the system records—whether you want it to record continuously 24/7 or set up motion detection with grids and sensitivity settings. Create a customized recording schedule tailored to your unique security approach. The system will automatically overwrite the oldest footage when it fills up, so you don’t need to worry about manually managing your recordings; just be sure to export video if an event you need to save long-term happens.

There are multiple ways to access, watch, and manage the system, including from a computer using the free remote viewing apps, camera monitoring software, or web interface in the local network.
