Product introduction
The 540 TV line definition LTC 0495 series is a high-performance 1 / 3-inch digital CCD Day / night camera, which can shoot excellent quality images at any time. It can automatically switch from color mode to black and white mode according to the lighting conditions of surrounding environment.

Exclusive use of 15 bit digital video processing technology, improve the sensitivity and XF super dynamic function, so that the camera has a very wide dynamic range, so it can shoot clearer and more realistic color images.
All dinion cameras will be ready for use at the time of delivery. The user only needs to make a simple connection, adjust the lens focus and connect the power supply. It can adjust the rear focus and connect the power supply without any tools. If fine adjustment or special settings are needed in the extremely harsh conditions, the user can adjust the parameters of the camera by using the control button on the side of the camera and the screen display menu (OSD). The camera can automatically detect the lens type. The lens guide ensures precise rear focus adjustment, so the camera can shoot a clear image at any time.
basic function
XF ultra dynamic range
The camera adopts 15 bit digital signal processing technology, which can automatically generate highly accurate signals, so it can capture any details of the bright and dark areas in the scene at the same time, so as to display as much information as possible in the image.
Bilinx communication technology
Bilinx is a two-way communication function through which data can be embedded into all video signals generated by Bosch dinion cameras. Technicians can check status, change camera settings, and even update firmware from anywhere through the video cable. Bilinx shortens the service and installation time, allows users to set and adjust more accurately, and improves the overall performance of the camera. In addition, bilinx can use standard video cables to transmit alarm and status messages, so it can provide excellent performance without additional installation steps.
Video motion detection
The built-in video mobile detector allows users to select up to four zones that can be fully programmed, and each zone can be set with different thresholds. The full scene change detector can detect false alarms caused by sudden changes in lighting conditions, such as turning on or off indoor lighting devices or safety lighting devices, thus reducing the false alarm rate. When the output relay is closed, if movement is detected, the alarm will be displayed on the video monitor and the alarm message will be transmitted via bilinx.

Automatic black level

The automatic black level function improves the contrast by compensating for low contrast situations (such as glare, smoke, etc.).

Default shutter

LTC 0495 has a fast default shutter, which can capture images of moving objects in sufficient light. When the light intensity is reduced and other possible adjustment methods are tried, if the requirements are still not met, the shutter speed will be converted to the standard setting to maintain normal sensitivity.
backlight compensation
The backlight compensation (BLC) of the target area can be fully programmed by the camera, and the backlight compensation level is variable, so the camera can be easily set up for the most challenging occasions such as entrance.
Camera Guide
The lens guide can automatically detect the lens type and help users focus the lens at the maximum aperture to keep the camera in the best focus state for 24 hours a day. No special tools or filters are required.
Programmable mode
Three independent operation modes are preset for the camera, which can be used in typical applications, but for some special occasions, comprehensive programming is allowed. Through bilinx or external alarm input, the three modes can be easily switched.
Day / night mode
The day night LTC 0495 camera provides better night vision by increasing infrared sensitivity. The infrared filter can automatically switch from color mode to black and white mode by sensing light intensity or alarm input. The filter can also be manually switched through the following ways: alarm input, camera menu or bilinx coaxial cable control interface. Through the lens infrared detector, the camera interior improves the stability of black and white mode, because it can prevent switching to color mode when infrared light is dominant.

Increased sensitivity

By increasing the cumulative time on the CCD (up to 10 times), the effective sensitivity can be significantly increased. This is especially suitable for the situation where the light source can only be provided by moonlight.
