Megapixel IP camera, PIXC Focus – the clear picture!

Megapixel IP cameras – crystal clear pictures with excellent post zoom capabilities.

But, how much attention is paid to the quality of lens used?

And, back to basics, how many are focused correctly?

I saw a great camera recently, the picture was pin sharp, the colours vibrant, the focus absolutely spot on……………but was it? Night fell, the TDN (True Day Night) IR Cut filter kicked in and the picture was less than great! fuzzy around the edges, and the previous pin sharp objects were, well, not pin sharp anymore………….

Back in the day (around the times of horse, cart, gas lighting and CCD cameras) an experienced engineer would have a ‘night glass’ to help set up cameras……….now don’t get me wrong, I am not advocating that engineers should start working all hours through the night, but a simple piece of welding glass or similar near dark glass device would help the engineer align both focus and iris (if electronic) during daylight hours………….if the picture is good at night, it will be good during the day

But it doesn’t stop there…………what lenses are being used with these new high quality cameras?

We’ve seen really cheap, entry level lenses being used on these cameras…………now, that’s kind of like watching normal resolution television on a HD TV……it works, but you don’t get the same experience!!

SO, make sure you select the right lens for the camera………..treat it to a purpose built Megapixel lens…………or at the very least, a good quality well made aspherical lens…………

Don’t think saving a few quid on the lenses will deliver the same results!
