Canon develops two CMOS sensors for video surveillance

The new sensors of Canon are the LI7070SAC that can capture full HD video in low-light environments. 0,08 Lux, and the LI7070SAM that works with a minimum of 0,04 Lux. This makes them ideal for night surveillance.

Canon and Canon Marketing Japan have announced the CMOS sensors (Complementary Metal Oxide Semiconductor) of 1/1,8 inches LI7070SAC (Color) and LI7070SAM (monochrome) for security applications, Industrial & Medical.

They have an improved capacity to Near-infrared shooting, in addition to a capture function High dynamic range operating in environments with significant contrasts between light and dark, and the possibility of high-sensitivity shooting in low-light environments.

In recent years, the demand for near-infrared imaging capabilities for surveillance and industrial cameras has multiplied. This is why the applications of these CMOS sensors for use in traffic surveillance and industrial applications have increased.

The infrared sensitivity near the LI7070SAC has increased by approximately 2,4 times compared to that of the LI7050 (launched in October 2020), which also measures 1/1,8 inches and has about 2,12 Effective megapixels. This allows surveillance in dark environments that cannot be controlled with the naked eye.

These sensors can also be used in industrial environments, for the inspection of dark areas, and in medical settings, such as fluorescein angiography.

In addition to near-infrared capability, Both sensors incorporate a HDR mode that expands to a range 120 dB its capacity by a double exposure method that superimposes two images with different exposure times. This allows you to capture high-quality images while limiting overexposure and shadows in conditions where there is a large difference in brightness, such as when a light is turned on to carry out inspections inside tunnels.

The sensor achieves a range of 75 dB even when operating under normal conditions.

This firing capability, even in low-light situations, increases the application possibilities of these sensors.

Although their dimensions are small, The composition of the pixels has been designed to allow high sensitivity, while reducing the noise level.

The LI7070SAC can capture full HD video in low-light environments of 0,08 Lux, while the LI7070SAM works with a minimum of 0,04 Lux , which makes them models especially suitable for the Night surveillance of public facilities, Roads, logistics centers, Etc., in addition to its use in cameras equipped with underwater drones and those integrated in microscopes, requiring compact image sensors with a high degree of sensitivity.
