IPC-Color4k-T question

[TheE]

In your opinion or experience, would the 3.6mm IPC-Color4k-T be a good option to cover the entry/exit of normal size doors? Or would the focal length be too far off?

In my testing they were a little fuzzy at 6ft, real bad inside of 6ft, and crisp and clean at 12-15ft

Appreciate your time in providing this helpful feedback.

+1 above. Many are finding that 4K full color on the 1/1.2" sensor is a low light machine, but they make better overview cameras to capture color rather than IDENTIFY unless the distance is the rather small distance depth of the camera. So if the distance to IDENTIFY is 12-15, then good choice if that is the goal of the camera.

Very good info, thank you!

@wittaj Which 4K Full Color have the 1.2" CMOS? I can only find them in the 1.8", which is a worthy sensor in itself. Only the large SD8C845FG-HNF
PTZ has the big sensor (IMX585) that I could find. Wish more had the 1/1.2". The 1.8 is excellent though, and the 1.2" is not cheap.

The 4k-X and the 4K-T

 

[bigredfish]

Turret
IPC-HDW5849H-ASE-LED - Dahua International

Bullet
IPC-HFW5849T1-ASE-LED - Dahua International

Both are fixed lens only (No variable focus) and both lack IR capabilities so you need to be sure you have enough light to use them

TY gentlemen.....

Night Examples
Turret 3.6mm- No light except the LEDs of the camera. Its Black back there
About 20-25ft to boat

Bullet 3.6mm with dim streetlight I still run the camera LEDs at 75% @40-45ft

The color 4K's are impressive. The planters/flowers really pop on the dock. Sodium lights on the bullet killing the white balance. Great examples. Thanks for taking the time. Gotta love those 1.2" sensors.....

 

[bigredfish]

Yeah, and the LEDs on the bullet I swear are just about brighter than the old dim streetlight. Both running 1/120-1/250 ish exposure
