4k 8MP vs 12MP ?

[micgo]

Hello guys. i m new on the boat! please go easy on me.

i m looking to install 16 to 24 cam at a school location. after some reading from google/reddit i got here to ask more questions. Annke is having a Flash Deals. and i m trying to pick using C800 (4k8MP) or C1200 (4k12MP). is it worth going to 12mp ? some reddit posted there isn't a huge diff and i should look at image senor

Model	Sensor
C800	2.4​	0.416667​
C1200	2.8​	0.357143​

please give me some idea.......... any input will help!

Thx!

The C800 (4K/8MP) specs show that it has a 1/2.4" sensor which is more suitable for a 3MP camera with 1/3 of that resolution. It's low light performance, especially with motion, will be dismal. The 12MP would be even worse.

A 8MP camera should have sensor no smaller than 1/1.2" as shown below.

Is it a public school and would need to comply with NDAA requirements?

In general, those sensor sizes per those resolutions are considered rather small for low light image capture.

If you're really wanting to get these, Best to buy one of each to compare under real world testing for your setup for the next time they have a sale.

Otherwise, I prefer larger sensors.

Hi @micgo

We have a number of threads on this topic, and Andy has a sale going on for Dahua OEM models many of which you can find with larger sensors.

In general the 4MP 1/1.8" models are well liked for low light performance.

Note, there's a lot more to picking cameras besides resolution and FOV .. you need to have ideas of the placement locations you are considering and what you functionally want to accomplish.

Best place to start is picking up one varifocal Dahua OEM or HIkvision OEM camera 4MP 1/1.8" sensor IP PoE camera and a small PoE switch good length of cat5e cable with 23 24 awg copper wires, and setup a test rig.

It takes time to learn more of the basics before you should just jump into buying a full kit unless you are willing to spend more money by buying your first kit which would be your learning experience.
