model number difference

[bug99]

What is the difference between the E-Z and the R-Z model numbers? like in the HDBW5830E-Z and the HDBW5830R-Z? I couldn't see any difference, except for some reason the E-Z is 1" larger.

Is there a Dahua cheat sheet?

Template:NameConvention - Dahua Wiki has the decoder information for model numbers.

In this example the difference is the "case sequence", or the actual case... From the links @glitch1985 provided:

5431R-Z:

Casing: Metal

Dimensions: Φ122mm×88.9mm (4.8”×3.5”)

Net Weight: 0.5kg (1.1lb)

Gross Weight: 0.58kg (1.29lb)

5431E-Z:

Casing: Metal

Dimensions: Φ159.1mm×117.9mm (6.26”×4.64”)

Net Weight: 0.89kg (1.96lb)

Gross Weight: 1.13kg (2.49lb)

I had a tough time finding that link/reference at the time as well. I think @HalfMoon has it right. I see this as being a minor thing. I normally want the smaller one (size matters ), but the larger E-Z might be convenient for two reasons.
1. drops on to existing or a wider range of mounts
2. same model series can support a Z5 length focal lens, without changing look and feel (if that matters to someone).

I remember seeing something posted which identified each character in the model and gave a description of what options it had but I haven't been able to find it.
