is the internal mainboard for various 4, 8, and 16-channel Hikvision DVR models Revision 1.2 ds-80249 -p rev 1.2 schematic

If you are holding a PCB labeled "DS-80249-P Rev 1.2," you need exactly this schematic. Using Rev 1.0 could lead to short circuits or incorrect voltage measurements. Often uses an FAN7601 or FAN7382 (depending on

Many DC-DC converters have an enable pin that must be pulled high via a resistor. Rev 1.2 schematics often add a voltage divider on the EN pin to implement under-voltage lockout (UVLO). Measure the voltage here; if it is below 1.2V, the converter will stay off. Many DC-DC converters have an enable pin that

This specific board revision is central to various Turbo HD DVR models. It manages high-definition video compression, storage via SATA interfaces, and network connectivity for remote viewing.

Rev 1.2 introduces a (TPS54260 or similar) replacing the linear regulator of Rev 1.0 for improved thermal performance.

Without a specific manufacturer name, here are the most likely candidates for a document numbered "80249":
