Looking for a new DVR to hook up to our existing security cameras. Preferably low cost with an easy to use interface.

We currently have 4 wired cameras with Siamese cable connections. We may add 1 or 2 wireless cameras in the future, but that is not a guarantee. Our Swann DVR crapped out. I hate their UI so would like to avoid that brand or any brands with a similar UI. I have plenty of HDD/SSDs so am not opposed to a DVR that requires adding my own (plus that allows for upgrading storage in the future). I don’t care about cloud storage or remote access.

Thank you for any insights you may offer.
