Firmwares
​

Please be aware that if you have purchased your Hikvision products from an online source or unauthorized distributor, they may not be compatible with the firmware downloaded here and are considered to be “gray market” product. If your camera has “CH” in the serial number, you are most likely using a “gray market” product. Updating the firmware from this site may lead to several complications in those cameras, up to and including camera failure. Restoring a “gray market” product to its original condition is a factory process and will result in a Chinese interface. As Hikvision warranty is void in this case, you must rely on the dealer for any service, support, and warranty of the “gray market” product.
