Technical specifications for the Lorex B451AJ indicate the use of an Ambarella chipset paired with a 4MP CMOS sensor, producing a native resolution of 2560x1440. Aggregated specification data lists a Class 10 microSD slot supporting up to 256GB for local data retention, which enables the system to operate without recurring cloud storage fees. The hardware supports dual-band Wi-Fi connectivity at both 2.4GHz and 5GHz frequencies.
Performance metrics demonstrate that the IP65-rated polycarbonate chassis includes a glowing LED ring for visual indication. The 2K sensor configuration is optimized for high-bitrate local recording, though thermal analysis shows the unit can reach elevated temperatures during sustained high-resolution capture. The 164° diagonal field of view provides wide-area coverage, while edge-based AI processing is utilized for person detection.
Standardized testing protocols indicate that a 16V-24V AC transformer is mandatory, and the included Chime Kit must be installed to maintain voltage regulation for mechanical solenoids. The firmware provides support for RTSP and ONVIF, facilitating integration with local network video recorders.
The Lorex 2K Wired WiFi Camera is a high-performance alternative to the Ring Wired model for users who require higher resolution and local NVR compatibility.
This unit represents a prosumer-grade entry in wired video doorbell systems, emphasizing local control and high-fidelity imaging.
