I recently bought a 4 bedroom house (very similar to this)

I want to buy a security system that can let me place 4 cameras around the house, just so at any time I can view the surroundings of my house.

What would be the most reliable and budget setup for this? I’m looking for something that would have no subscriptions as I don’t want to be paying an extra $10/month just as principle. I have looked at the following but not sure which would be good for my usage:

I have also taken a look at Eufy and even self hosting via Blue Iris but I’m still unsure which direction to go towards. I am pretty tech-savvy but not very “handy” so I would prefer something that’s as easy to setup and maintain as possible.

Another requirement would be object detection as I find that’s pretty important… Something that can send notifications to my phone. Would be great if the system is company-agnostic so if for example the company just disappears 1 day, I’m not stuck with a dead product with limited functionality.

Ideally my budget would be around $800-900 CAD (600-700 USD) for the NVR + at least 4 cameras. Sorry for the long post but I wanted to include as much information as I can

Thanks!
