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.
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.
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!
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.
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
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, license plates, windows or areas where privacy is important.
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!
