REOLINK vs SEHMUA Camera Specs
Resolution Quality
The REOLINK RLC-810A records in 4K Ultra HD, which is 8 megapixels. This provides 1.6 times more detail than 5MP and four times more than 1080p. The SEHMUA S40 captures 2K video. While 2K is sharp, it offers less clarity than 4K. If you need to zoom in on small details like license plates, the higher resolution of the REOLINK is superior. The SEHMUA supports 4x digital zoom, but this is limited by its lower base resolution. For maximum image fidelity, the REOLINK wins.
Connectivity Type
These cameras use completely different connection methods. The REOLINK uses Power over Ethernet (PoE). You run a single network cable to transmit video, power, and data. This requires wired installation near a router or NVR. The SEHMUA uses 4G LTE cellular connectivity. It includes a built-in SIM card and works anywhere with 4G coverage. It does not need Wi-Fi or wired power. The SEHMUA is better for remote locations like barns or construction sites. The REOLINK is better for homes with existing network wiring.
Power Source
The REOLINK RLC-810A draws power directly through its Ethernet cable. It does not have a battery or solar panel. You must ensure the PoE switch or injector is powered. The SEHMUA S40 is solar-powered with a built-in large capacity battery. It includes a 6W solar panel to keep working in sunlight. It is truly wireless and cordless. The SEHMUA is the clear choice if you lack electrical outlets. The REOLINK requires a wired power solution via the network cable.
Camera Movement
The REOLINK RLC-810A is a fixed bullet camera. Its field of view is static once installed. You must aim it carefully at your target area. The SEHMUA S40 offers pan and tilt capabilities. It rotates horizontally and vertically via the app. This allows you to adjust the viewing angle remotely. The SEHMUA provides a 360-degree live view. If you need to scan a large area or change perspectives without moving the hardware, the SEHMUA is more flexible. The REOLINK is better for fixed, specific monitoring points.
Motion Detection
Both cameras detect motion, but they use different technologies. The REOLINK uses smart AI detection to identify humans and vehicles. It minimizes false alarms from animals or shadows. You receive specific alerts about what was detected. The SEHMUA uses a PIR motion sensor. It detects movement of people or animals and sends push notifications. You can adjust sensitivity in the app. The REOLINK offers more precise classification of events. The SEHMUA provides reliable basic detection. The REOLINK has the edge for accuracy.

Users wanting maximum video clarity and smart detection
The REOLINK RLC-810A delivers 4K Ultra HD resolution, which is 1.6 times clearer than 5MP and four times clearer than 1080p. It uses AI to distinguish between people and vehicles, reducing false alarms from animals or shadows. This ensures you only see relevant events in your live stream or playback.
Installations without Wi-Fi or wired power access
The SEHMUA S40 operates on 4G LTE and solar power, requiring no Wi-Fi or electrical outlets. It includes a 6W solar panel and built-in battery for true wireless placement. This makes it ideal for remote locations like farms, barns, or construction sites where traditional wiring is not available or practical.
Viewers needing flexible camera angles and night vision
The SEHMUA S40 offers horizontal and vertical rotation for a 360-degree view, allowing you to adjust the angle remotely. It features full-color night vision with a manually enabled spotlight. This combination provides broader coverage and clear visibility in dark conditions, unlike the fixed position of the REOLINK bullet camera.
