Vari-Focal IP Camera 1.3 MP IR Waterproof QH-NW351


1.3 Megapixel IR Waterproof Camera ,⅓ Progressive Scan CMOS ,H.264 Support Triple Streaming.
  • Vari-focal Ip Camera

    Equipped with 2.8mm to 12mm Vari-Focal auto iris lens allowing easy installation and camera angle adjustment. Manually adjust the lens to desired field of view with a range for available focal lengths.

  • Day and Night

    Experience the Difference Megapixel IP camera delivers color images during the day. As light diminishes below a certain level, the camera can automatically switch to night mode to make use of near infrared (IR) light to deliver high-quality, black and white images.

sd card

  • Decentralized storage

    The video captured by the network camera is stored locally on the camera’s SD card.  A 32 Gbyte Sdcard typically stores 2-4 weeks of video. Eliminates the necessity and cost for an onsite server, DVR, NVR or PC for recorded video.

  • Redundancy

    Fail over recording if the camera loses connection with the central server.

Ip67 Rated

Built with the standards of IP67, 6 stands for “Totally protected against dust ingress.; complete protection against contact” and 7 for Protected against short periods of immersion in water.Ingress of water in harmful quantity shall not be possible when the enclosure is immersed in water under defined conditions of pressure and time (up to 1 m of submersion). Test duration: 30 minutes;  Immersion at depth of at least 1 m measured at bottom of device, and at least 15 cm measured at top of device.

Iphone Mobile Application

  • Seamless Compatibility

    View live video from one or multiple devices;

  • Recording

    Record live video on the mobile device and play the video that recorded on the device;

  • Remote

    Remotely playback the record files on the DVR or IPC;

  • Control

    Remotely Control pan-tilt-zoom cameras.

  • Alerts

    Notification on alerts and events; Takes a snapshot of the video and saves it on the SD Card or a specified folder.

Its a high-performance Build in 3A (AWB, AF, AE) which supports triple encoding streams and bi-directional and broadcasting real time audio transmission.

Intelligent Video Analytics
  • Smart Front

    “Smart Front” feature the special nature of network cameras is that it is based on open platforms can be more intelligent analysis of the application embedded in the network camera to meet the individual needs of the intelligent video surveillance, which means that a network with smart cameras as embedded in different pre-application, can achieve functional differentiation.

  • 4:3 Normal View and 16:9 Comparison

    You can see the wider 16 by 9 format feels more all natural, showing more of the picture plus acquiring a greater view. Therefore the wider format provides you with wider monitoring area.

video compression
  • H.264 Video Compression

    The high performance chip-set applied provides the the IP camera with an amazing 1.3 Megapixel High Definition Resolution up to 30 frames per second, and 720p HD images at 1280×720 also at 30 frames per second with Multiple H.264 streams and M-JPEG/MPEG-4 streams that ensure simultaneous real time monitoring and high-resolution recording at a lower bandwidth.

  • Digital Output

    Digital Output or DO is the pair of pins in the camera’s terminal block through which to connect an external device with the camera. That external device can be activated by the camera upon an event inside the camera or by the command from the control center.

  • Digital Input

    Digital Input or DI is the pair of pins in the camera’s terminal block through which it is possible to connect an external device (a switch or some kind of sensor) with the camera, allowing the external device to notify the camera about an activity in camera site.

  • IR Cut Filter

    This feature allows the sensor to form images even under low illumination conditions that a human eye would find difficult to do. The ICR (IR-Cut filter Removable) is an apparatus that is placed between the camera sensor and the lens, and allows the IR-Cut filter to be placed or removed from the front of the sensor, depending on the illumination level. The ICR is a mechanical shutter, typically powered by a motor, with NIR filter and plain glass panes.

  • 2 Way Audio

    With external microphone, Capture sounds coming from a monitored site and relay it back to the remote monitoring base. The person in charge can then literally speak to the people around the camera ip via attached speakers to issue instructions, warnings, etc.

  • Multiple Streaming

    Qihan IP camera supports multiple streaming resolutions for various user applications.


  • Onvif Compliant

    Designed to enable security solution designers and integrators, to more easily identify features supported by a product. Compatible with any Onvif Compliant hardware.


Various alarm sources including alarm input ports, motion detection, intelligent video detection can trigger the cameras alarms then sends snapshots to an FTP server, SD Card or NVR. Alarm notifications are also sent via Email.


  • Multiple Codec Streaming

    Multiple Codec H.264 and M JPEG can be transmitted simultaneously, enabling multiple purposes such as real time recording, high quality or efficient monitoring, noisy populated background and idle background recordings.

  • Power Over Ethernet

    Since power is supplied through the LAN cables, there will be less complicated cabling and the installation cost will be substatially reduce. Some PTZ models supports POE (**OPTIONAL)
