DVR Hikvision 4‑channel 5MP H.265 AcuSense model 52780 — 4 video inputs, H.265 compression

The Hikvision DVR 4‑channel 5MP H.265 AcuSense model 52780 is a compact digital video recorder designed for small surveillance installations. It accepts up to four 5MP camera inputs, uses H.265 video compression to reduce storage requirements, and integrates AcuSense analytics for event classification and faster footage search. The device supports continuous and event-based recording, remote monitoring, and reliable playback for routine security checks and incident review.

Advantages

This DVR combines 5MP video support with efficient H.265 encoding to maximise recording time while conserving storage. AcuSense analytics improves detection accuracy by distinguishing human and vehicle targets from other motion, reducing false alarms and simplifying evidence retrieval. The four-channel design fits compact systems where space and budget are limited, and remote access features allow live view and playback from mobile and desktop clients.

Suitable for

• Small business premises (shops, salons, warehouses)
• Residential properties and apartment entrances
• Small offices and reception areas
• Remote monitoring of garage or storage rooms

Key specifications

• Channels: 4 video inputs supporting up to 5MP resolution
• Video compression: H.265 for reduced bitrate and storage
• AcuSense analytics: human/vehicle classification and event filtering
• Recording modes: continuous, scheduled, and event-based recording
• Remote access: support for mobile and desktop remote viewing and playback
• Storage: internal HDD support (single drive bay typical for compact DVRs)
• Playback: multi-channel simultaneous playback and timeline search

How to use

Install the DVR in a ventilated location near power and network connections. Connect up to four compatible cameras to the video inputs and attach a compatible hard drive for local storage. Configure basic network settings to enable remote access, set recording schedules and event-trigger rules using AcuSense options, and adjust camera and recording parameters from the device interface or companion software. Verify motion detection zones and sensitivity to optimise event accuracy before relying on automated alerts.

Usage recommendations

For reliable long-term recording, use a surveillance-class hard drive sized according to retention needs and enable H.265 compression to maximise storage efficiency. Regularly update firmware and verify AcuSense settings to keep classification accuracy current. Position cameras and set detection zones to minimise false triggers from vegetation, reflections, or street traffic.
