Hi,
Welcome to our Forum, from what I can see with the manufacturer specification sheet of the WATCHDOG DW VMAX960H 16 this recorder is an analog recorder with a resolution input of 960H, D1, 2CIF, CIF.
The HDOB-SB2IRW is able to output 4 different video outputs (CVI/TVI/AHD/CCTV) CCTV being Analog. This camera will output 960H at the analog side and up to 1080 on the CVI, AHD and TVI sides.
Yes, it is compatible! But consider upgrading to a new recorder as this camera can provide you with exceptional resolution, unfortunately, your current recorder will only accept analog inputs.
