What modern video surveillance for an apartment?

Question

CCTV

Good afternoon!
It is necessary to organize video surveillance in the apartment.
You need one camera in the peephole - into the internal elongated corridor for 3 apartments and the second into the common corridor in the anti-vandal outdoor panel like this one - https://videotechnology.ru/d/vp/falcon-eye-fe-305c...
That is . cameras will be used both to watch who came and to record by movement.
In this regard, a number of questions arose:
- for such purposes, which cameras are better to take - analog or IP?
- what is better to choose - a water intercom with the ability to record or a separate DVR or NAS.
- if you use a DVR or NAS, then what are the options for implementing camera viewing - a la video intercom mode - for example, attach an old tablet to the wall?
Please share how you organize it.

Answer 1

You buy IP cameras and what kind of thread is a simple NAS from Synology, they seem to have a software in DSM to connect IP cameras. Nas is working - the video is being written.
I ordered a video intercom from alik for 5-6 thousand. On movement, the recording on the built-in memory card is automatically turned on. It has been working fine for over a year now.
Whichever is easier, take it.

then what are the options for implementing camera viewing - a la video intercom mode - for example, attach an old tablet to the wall?

This is a perversion.

Answer 2

IP video peephole, choice?
As a result, I brought a vitukha over the front door for myself, I haven’t bought an
IP camera yet, of course
