Video Surveillance Camera Enhanced by Cohu Electronics

January 10, 2013

Cohu’s 3720HD Series Dome Camerai includes 30x optical zoom, low light sensitivity, EIS, defog image enhancement, & IP66 outdoor protection.

The 3720HD is designed to operate in harsh weather with its IP66 enclosure protection which minimizes the effects of water intrusion, pollutants and corrosives. The manufacturers claim it will deliver years of clean, reliable images and is backed by a two-year limited warranty.

The 3720HD dome camera offers three times the low light sensitivity of first generation Helios™ HD cameras. True day/night technology using a removable IR cut filter produces exceptional sensitivity down to 0.005 lux. The increased zoom magnification to 30x offers more than one and one-half times the previous 720p 18x technology, resulting in dramatically improved imaging performance to see and identify objects at greater distances.

In addition, advanced image processing capabilities compensate for vibrations or movements of the camera using an advanced Electronic Image Stabilization algorithm. Finally, Cohu’s real-time Defog capability produces enhanced images in obscured haze and foggy conditions commonly encountered in surveillance and traffic monitoring applications. The image processing measures each pixel for fog thickness and enhances contrast to deliver an improved image.

The 3720HD Series dome camera includes a variable high-speed pan and tilt drive, with 360° continuous pan and +0 to -90° tilt. Fast positioning speeds result in 180° movements in less than two seconds. Providing multiple video stream capability, the 3720HD delivers two independently configured H.264 streams or an H.264 with MJPEG. The 3720HD operates on either 24Vac or PoE+ (Power over Ethernet) inputs.

The 3720HD provides a full function web server, allowing complete administrative and operator control capabilities. Administrative features include configuring network settings, user password assignments, setting video streaming properties, configuring camera imaging properties, defining presets and tours, and assigning camera ID labels.
