4. What is the difference between HD-CVI, HD-TVI, and analog cameras?
HD-CVI and HD-TVI: Technologies that enable HD video transmission over coaxial cables, offering improved image quality compared to analog cameras.
Analog Cameras: Transmit standard-definition video and are less expensive but do not provide the high resolution of HD cameras.
5. Do HD cameras work with any DVR?
HD cameras are compatible with HD DVRs that support HD-CVI, HD-TVI, or AHD technologies. To ensure compatibility, we recommend pairing the camera with a DVR from the same series (e.g., Elite or Sibell).

Yes, most of our HD cameras feature infrared (IR) night vision, allowing them to capture clear footage even in complete darkness. IR ranges vary, with many cameras covering distances of 65 feet or more.
7. Are these cameras weatherproof?
Many of our HD cameras are designed for outdoor use and come with IP66 or IP67 ratings, making them resistant to harsh weather conditions such as rain, dust, and extreme temperatures.
8. What lens options are available for HD cameras?
