N-CAM 870 M7486 PTZ camera has been designed for use in CCTV systems based on HD-TVI DVRs. The camera provides 1080p video. With high sensitivity (0.01 lx) and built-in IR illuminator with range up to 80 m, the camera ensures high quality image in low light or even no-light conditions.
By default, the camera operates in HD-TVI system, but the user can switch it to AHD or HD-CVI system (the procedure is described in the user manual).
The motozoom lens with auto-focus can operate within 5-50 mm focal length range. The PT mechanism provides 0o...250o pan range with angular velocity up to 15o/s and -10o...55o tilt range with angular velocity up to 10o/s. The built-in memory has the capacity to store up to:
- 255 presets
- 8 patrols,
- 4 routes.
All camera settings can be made using the video signal cable. The control is possible after selecting PTZ menu option of a compatible DVR. After switching on the OSD menu of the camera, the user has access to all configuration options. More details can be found in the "Downloads" section.
Mechanical IR-cut filter ensures perfect color rendition in daylight and full sensitivity with IR lighting.
High Definition Transport Video Interface (HD-TVI) allows users to send uncompressed, high-resolution video (up to 1080p) over coaxial or twisted-pair cables (using dedicated baluns). The transmitted video signal is in analog form, with bandwidth much greater than in the case of CVBS (SD). As the signal is not compressed, the picture is more natural during live viewing. There is no delay and the configuration of such a system is easier compared to IP CCTV solutions.
Main advantages of HD-TVI systems:
- no delay
- natural live image due to lack of video compression
- video transmission via coaxial cables
- high resolution – 720p, 1080p, or even 3 MP
- tribrid DVRs – support for HD-TVI, CVBS and IP cameras,
- high resistance to electromagnetic interference through the use of QAM synchronous amplitude modulation and separation of luminance and chrominance signals
- much easier configuration compared to systems based on IP protocol
- two-way communication – access to OSD menus of cameras and PTZ control via the video cable, directly from the HD-TVI DVR
- maximum video transmission range even longer than in the case of CVBS signals
HD-TVI systems allow for sending additional signals over the video cable
HD-TVI system can transmit a range of signals via a single coaxial cable:
- HD video from the camera
- Audio from the camera
- PTZ commands to the camera
- OSD menu control commands to the camera
