Hi!

I have a quote from a security company to install 4 cameras and the NVR. They priced out the same layout but with two different quality cameras. The NVR is the same for both – Dahua Technology N41C1P 4-Channel 4K UHD NVR with 2TB HDD.

On the more expensive quote,the only difference is that they would install I guess fancier cameras . These would be Dahua N42DJS2. The cheaper quote is for Dahua N41CJ02.

The way that the representative explained it to me, is that they are both great cameras, deal with the elements and night vision pretty fine. I think maybe the better one also supports microphone/speaker cababilites, which I don’t really care about.

What I am interested in is the ability to have a motion detection/alert. Ie, I would like to have some sort of notification if a person (or car maybe? ) starts creeping around my front door or backyard.
The representative made it seem that the cheaper cameras technically have a motion alert, but can’t tell the difference between a branch moving in the wind or a squirrel versus a real person. And of course, alternatively, the more expensive cameras are optimized to distinguish people from irrelevant things.

This all made sense to me. But I am not technical minded at all. My husband, who granted has no camera/security expereince, but does work in software, took a look at the specs for everything. And he claims that the cameras really have little to do with it, and it is the NVR which we would basically configure to recognize targets. And since the NVR is the same for both quotes, that the cheaper cameras are just fine.

Is this right? For reference, the fancy camera quote is for 1812.91 all in, and the cheaper camera quote is 1374.00 (quotes include install, equipment, etc).

Thoughts? I greatly appreciate any guidance!
