Replacement of the old intercom with a new vandal-proof video intercom (plus additional CCTV camera)

Video from the test after installing the HIKVISION DS-KIS203 analog video intercom system equipped with an additional CCTV camera. It is an analog, vandal-resistant set, adapted for mounting on a narrow post and suited for transmission over ordinary YTDY multi-wire intercom cables. It works in places where ordinary small intercom systems have been used so far or where digital transmission is not possible, while offering very good image and sound quality.
