I recently moved into a new place and noticed a bunch of these wires in a few spots outside of my unit and the other unit in my condo building. ChatGPT suggested they might be a low-voltage communication cable but was pretty uncertain. Sorry it's a low-quality picture, I thought it was better quality when I was looking at the picture after taking it.

Could I use the cable to potentially power a security camera? I'm trying to gauge what kind of security camera to install, and would maybe use one of these wires to power a camera

I recently moved into a place that has a DS-KH6320-WTE1 intercom system and a DS-KV6113-WPE1 camera setup already. I'm looking to have video recorded and saved, so am thinking of either getting a compatible NVR or just another camera like a Eufy to record and save video.

I'm new to home security and this stuff - would you recommend getting a compatible NVR?

How do I see if one is compatible with the products I already have? Do I even need to get a Hikvision NVR? What features should I look for or ignore in selecting an NVR?

If I decide to buy a Hikvision product, it seems like I have to go through a distributor (I'm in the US). Is there a way to find one that has a brick and mortar store in a specific city? I've gone through the 'Find a Distributor' page online and it hasn't been too helpful other than listing all the distributors.

I'm trying to gauge if a table I have is built correctly. Let's say I have data coming from multiple sources/applications for employees so the table I'm trying to evaluate is dim_employee. There is some precedence/hierarchy of how data should be updated from the different systems, and I have that sorted already.

The data is currently being loaded from all these sources into the same dim_employee table but as different records from each system. So an employee with EmployeeID of 12345 can have up to X number of records in the table, where X is the number of source systems. They're just differentiated by a field source_system that is populated with the name of the source system.

A few options that come to mind are:

1. Have different tables for each system, like dim_employee_google, dim_employee_microsoft, and dim_employee_apple.
2. Keep it as the same table but have additional fields for specific source systems, which are updated by the respective load process. So Load_google_process would update dim_employee.pay_info_google.

What should I consider to see if either of those options make sense? I'm already leaning towards keeping the table the same, but don't know the modeling theory well enough to put a grasp on it

I recently moved into a place that has a DS-KH6320-WTE1 with cameras and I've been trying to go through the manual and other files online to see if I can record + save videos on it. It seems to only save videos if the doorbell is rung, but I want to also record 24/7.

I tried inserting an SD card but it's not allowing me to format it and giving me a vague error message, so I can't tell if I'll be able to record. Any help/insight would be much appreciated!

I'm surprised at how expensive fractional plates are. They all seem to be > $70 for a set of just 5, 2.5, and 1.25 pound plates. Where can I get a set of just 5 and 2.5 pound rubber plates for under $50?
