Modern NVRs and cameras support remote viewing — from your phone, a laptop, or another office. Setting it up varies by vendor.

1. Vendor mobile apps

Each major brand has its own app:

  • Hikvision: Hik-Connect
  • Dahua: DMSS or iDMSS
  • Hanwha: Wisenet WAVE Mobile
  • Axis: Axis Companion
  • Ubiquiti UniFi: UniFi Protect
  • Reolink: Reolink app

Install the app and add the NVR/cameras by either:

  • Scanning a QR code shown on the NVR
  • Entering the cloud account credentials
  • Entering the NVR's IP if on the same network

2. Web access

NVRs typically have a web interface accessible by IP — but this requires:

  • Same network as the NVR, or
  • VPN to the office network, or
  • Port forwarding (we discourage this; security risk)

Browse to the NVR's IP from your work laptop on VPN. The interface shows live and lets you scrub recordings.

3. VPN approach (recommended)

For security, the right way is:

  1. Connect to office VPN from wherever you are
  2. Open the NVR's web interface or the vendor app set to the local IP
  3. Same access as if you were at the office

This avoids exposing the NVR to the internet, which is a major security risk.

4. Cloud connectivity

Most modern NVRs offer a vendor cloud service (Hik-Connect, DDNS, etc.) that handles connectivity for you:

  • Create a vendor account
  • Add the NVR with its serial number
  • Sign in from the mobile app

The connection is brokered through the vendor cloud — no port forwarding required.

Tradeoffs:

  • Pro: easy
  • Con: vendor has access to your video stream; reliability depends on their cloud

If your IT policy requires no cloud, use VPN instead.

5. Multi-user access

Most apps support multiple users:

  • Share the NVR with colleagues via the cloud account
  • Each gets their own credentials and permissions
  • Manager can see all cameras; on-site staff can see only their location

Configure user roles in the NVR's user management.

6. Quality settings for mobile

Mobile data eats fast with high-bitrate streams:

  • Use the app's "fluent" or "standard" stream (lower resolution, lower bitrate)
  • Switch to HD only when needed
  • Most apps automatically lower quality on cellular

7. Two-way audio

If your cameras have speakers (intercoms, doorbells):

  • Some apps support push-to-talk from the phone
  • Look for a microphone icon in the live view

Not all cameras have this; check the model spec.

8. Push notifications

Apps can notify you of:

  • Camera offline
  • Motion detected (with snapshot)
  • Line crossing
  • Loitering

Configure in app settings. Be careful: aggressive motion notifications can drain your phone battery and annoy you. Tune to specific cameras or zones.

9. Notifications not arriving

If notifications stop working:

  • Check phone notification permissions for the app
  • Some Android phones aggressively kill background apps — exclude the surveillance app
  • Vendor cloud may be having an outage; check vendor status

10. Time zone gotcha

When viewing from another country, the NVR shows its own timezone. A recording from "10 PM" was 10 PM at the office — not your location. Most apps display in the NVR's timezone; some let you toggle.

When to ticket

Raise a ticket if:

  • You need a new user added to the cloud account
  • The vendor app isn't connecting and you've tried reinstall + correct credentials
  • You need offsite viewing set up for the first time
  • Specific cameras don't appear in the mobile app but show on the NVR

Include the NVR model, vendor, and what you're trying to do.
