I know I’ve been told many times to upgrade my system to ip cameras and a NVR but I’m not looking to do that right now. I have an off the shelf Lorex DVR system from Best Buy I’d like to get a better camera (single)

between these two which would be better?




This is what I have currently:

 
Full disclosure, I have no idea what I am talking about.

I am guessing most who comment will say the Dahua because it is on a 1/2" sensor, however, they will make note of an 8MP camera being on a 1/2.7 or 1/2 sensor is not the correct combination and neither will be ideal for low light situations.

I think I read somewhere that each 'step' in sensor size is a doubling of required light.

8MP on 1/2.7 needs 2x the light of 8MP on 1/1.8
8MP on 1/1.8 needs 2x the light of 8MP on 1/1.2

So, 8MP on 1/2.7 needs 4x the light of the 'correct' 8MP on 1/1.2 to produce the same night image.

As you noted, from OP's post, the one on the 1/2 sensor would be the 'better choice', even if not the 'best choice'.

OP, what's the reason for the upgrade? Better night image? In that case try to buy a camera on the 'correct' sensor size mapping.
Look at the chart at the end of this post and get a camera that's in the green section;

At the urging of several folks here, I created a thread to show the importance of focal length and how focal length can be more important than megapixels (MP). I mentioned some of this in the post regarding The Hookup’s latest video demonstrating different cameras, including one sold from a...

yes I am wanting to upgrade a camera that I have with low light. Had I known I shot myself in the foot by using BNC cameras I wouldn’t have to try and find an upgraded camera.
 
Maybe try to step down to 4MP on 1/1.8 sensors if you can in those locations (check your DORI numbers and make sure to pick a cam with the right focal length to have enough pixels)
 
2MP on 1/2.8 is in the green box, it'll give you a better night image.
Just make sure the focal length matches your installation location as you have less pixels now so your cam should be closer to the subject or have a bigger focal length to capture proper identification pictures.

Based on another post I found I went ahead and ordered one of these. Guess we’ll see how it works out for me

From where did you order it? One of the member on this forum, @EMPIRETECANDY, is a dealer. His Amazon store has some decent prices on cameras. Andy may also have some refurbished cameras available. There's a list in the link below. There's also info on how to contact Andy if you want to order one off the list. I've ordered a couple of refurbs from him before. They look like they may have been returns that had never been opened. I believe Andy's firmware is an upgraded version of the OEM firmware and is better maintained.

Andy, I noticed these in your store

What else is required to switch to ip cameras? Just the camera itself and a NVR? Might be something I can look into since the biggest issue of me going to ip is the cable run. Not that I can’t do it or terminate the ends, more so I just had my attic sprayed with 21” of insulation and I’m not a tiny rat lol. Thought about just tying onto the coax and pulling the cat 6 wire but if I hit a snag then I’m done :(

Are those coax/Ethernet converters powered by the Poe or they need an electrical outlet?

Just POE Power is fine, no need external power, this part we sell a lot, very stable and sometimes those coax cables in the wall not easy to bury new cables again.
