The Professional Difference

While resolution is important, a high-quality lens, a commercial-grade image sensor, and a powerful image processor are required to produce a professional quality image. Our goal in designing the AvertX HD838 4K autofocus zoom dome camera was to deliver a significant step up in image clarity, not to meet a 4K resolution spec at the lowest possible cost. The result is a world-class 4K experience that can be counted on in challenging lighting conditions and extreme environments. You will be amazed when you see it!

AvertX Smart Analytics

Increase detection accuracy and the effectiveness of your video security system with AvertX Person and Vehicle Detection. Using the latest machine learning analytic tools, AvertX video analytics accurately identifies persons and vehicles to reduce false alerts. Smart Analytics can be set to send push alerts to your mobile device when a person or vehicle is detected, or you can save time by searching recorded video for only analytic detection events.

Remote Controlled Autofocus 4x Optical Zoom

The AvertX HD838 dome cameras allow you to adjust the view and focus of your camera remotely without ever needing to climb a ladder. A fixed lens camera’s view is limited by how close or far it is from the targeted area. The HD838 with its 4x optical zoom gives you more choices for camera placement and to zoom in on what’s important to you. Once you have the view you want, autofocus gives you the sharpest picture possible.

Extreme Cold

Reduce False Alerts With Person And Vehicle Detection

AvertX Person and Vehicle Detection uses machine learning to analyze not only the motion in a scene, but unique shape and movement patterns to identify a person or a vehicle. Standard motion detection can be triggered by shadows, glare, bushes blowing in the wind or insects. PIR sensors can be triggered by thermal changes from the sun, barbeque cookers, heaters or lights. AvertX machine learning algorithms are designed to virtually eliminate false alarm notifications caused by standard motion detection or PIR sensors.

The Power of Megapixels

Higher resolution gives you the ability to enlarge an image and see critical details at a greater distance than before. Analog systems typically provide top resolution of 960x480 pixels, significantly smaller than the image provided by 4K  Ultra HD megapixel cameras. 1080p high definition is 1920x1080 pixels, similar to a 1080p HD television. AvertX 4K (8 megapixel) cameras capture video at 3840 × 2160 pixels. That’s four times the number of pixels of 1080p!

Smart Compression

Advanced Smart Compression

Maximize your bandwidth and NVR's storage with our H.264 Enhanced Codec. Using the H.264 Smart Codec, high quality video uses less bits of data. Less bits of data means you can store up to 50% more video than before on your NVR and use less bandwidth when viewing your video remotely. It's like being able to fit more of Grandma's cookies in your old cookie jar!

IR Nightvision

Superior Nighttime Performance

For scenes in total darkness, the HD838 dome camera uses the latest high-intensity IR LED technologies for maximum visibility. Adaptive IR technology adjusts illumination levels as an object approaches to keep objects close to the camera from being overexposed and washed out. If you prefer a color image, the HD838 can capture color footage with minimal security lighting. Often, a porch light is enough.

*IR range and image quality can be affected by surfaces that absorb or reflect the IR light differently when in total darkness. Camera location or position may need to be adjusted to optimize the images. Some ambient lighting provides the best results for night surveillance.

True Wide Dynamic Range

True WDR (wide dynamic range) compensates for uneven light conditions caused by shadows, sun glare, backlight, and inconsistent lighting. AvertX cameras with True WDR use multiple exposure technology that includes hardware and digital image processing. The result is superior video quality. See the True WDR video below for more information!

HD838 Pain Free Installation

Pain Free Installation

AvertX has designed its system with integral features to simplify installation. An integrated PoE switch means you only need to run a single cable to your cameras. At startup, the ProConnect NVR recognizes your cameras and starts recording. The key to a successful installation is planning. Please visit our DIY Corner for resources to choose the appropriate system for your home or business and tips and tricks for installing and getting the most out of your system. If you have any questions about your installation, call the AvertX PRO Team!

Camera includes 100’ CAT5e Ethernet cable for camera connections

Privacy Masks

Create a privacy mask on your AvertX camera to block recording and viewing of a designated area within the field of view of the camera. This feature allows you to block sensitive areas to protect privacy while still recording what is happening around it. A privacy mask gives you greater flexibility to place your cameras where they capture what you want, while maintaining the privacy or confidentially of assets, secure entry devices, documents, windows or areas where privacy is important.

Your Video Safe And Secure

The HD838 autofocus dome camera features a microSD card slot as an added layer of redundancy and backup. Once you add a microSD card, the camera will record directly to the internal storage on the card, making sure you always have video. If your recorder is stolen or fails, you can pull video directly from the camera’s microSD card and never miss an important event!

microSD card not included. See camera specifications for maximum storage card capacity and storage drive information.

Paintable Snap-on Cover

Instantly change the color of your AvertX dome camera with the included paintable snap-on cover. If you would like a different color, paint the cover and snap it on. It’s that simple!

Waterproof Camera Connectors

AvertX cameras are rated to withstand tough weather conditions for outdoor installation. To provide even greater protection from the weather, this camera is equipped with an IP66-rated waterproof cable connector and a matching IP66 connector for the included 100 foot Ethernet camera cable. This makes a water-tight connection, even in unprotected outdoor installation locations.
