Prompt shipment, fast delivery, well packed, in and working. Perfect picture recording on 3rd party NVR.
If I had chosen between two OV4689 and PS5510 sensors, I would prefer OV4689. It is better to transmit a picture than the PS5510 which is located in the top cameras of this page. PS5510 gives a more soapy image than OV4689 and 5 megapixels here rather interpolated full hd (I guess).
