Video Surveillance


TRT Communications, Inc. provides 4K IP surveillance cameras. 4K IP camera systems offer the highest level of detail and clarity available. The 4K surveillance cameras use advanced 8-megapixel image sensors and have approximately four times the amount of pixels as a 1080p HD security camera. This larger image sensor allows the camera to capture more light, which improves color, contrast, and low-light performance. It also adds an increased ability to zoom in on distant objects without drastically reducing image quality. So if an incident does occur, it will offer the best chance to capture useful evidence. 4K IP camera systems are also equipped with revolutionary HEVC (High Efficiency Video Coding or H.265) video compression. This helps keep files sizes low without losing the 4K video quality.
