Versatile, affordable, and reliable, this dome IP camera is an ideal entry-level surveillance solution for smaller indoor spaces. Available in 2MP or 5MP variants, it offers live and recorded video from 1080p HD up to quad HD (2592x1944) resolution. The motorised varifocal lens provides a horizontal field of view of up to 106°, allowing users to adjust for optimal coverage. It captures smooth, detailed video at up to 30fps, with the HDR feature ensuring clear visibility in diverse lighting conditions.

The camera can be easily wall- or ceiling-mounted straight out of the box, and setup is simple using the installation wizard. Equipped with IVA Pro Buildings analytics powered by deep learning, it enhances perimeter security and operational efficiency with accurate object detection. Alarms can be triggered if tampering or network disconnection occurs. The camera supports PoE for both power and network connection via a single cable, streamlining installation and reducing costs. It also supports on-camera recording with a microSD card (sold separately) with up to 2TB of storage.

Video Analytics

IVA Pro Buildings analytics enables real-time alerts for objects detected in the scene, using deep learning technology to enhance the accuracy of object classification. It reliably recognises people and vehicles while filtering out unnecessary notifications to reduce false alarms. Detected objects are visualised on-screen within bounding boxes for greater awareness. Users can run scenarios such as virtual line crossing, loitering warnings, and object detection within specific areas to improve security and generate actionable business insights. Footage can also be quickly retrieved using AI Forensic Search for efficient incident review.
