Choose strategic locations for each camera – common spots include:

Front door and back door

Driveway and garage

Backyard and side yards

Hallways or common areas (indoor cameras)

Mounting tips:

Mount cameras 8-10 feet high for optimal viewing angle

Avoid pointing cameras directly at bright lights or the sun

For bullet cameras, angle downward slightly to capture faces

Use the included mounting template to mark drill holes

⏱️ Time: 15-20 minutes

PoE technology is the magic behind ZOSI systems – one cable delivers both power and data to each camera. No separate power adapters. No nearby outlets needed.

Cable routing options:

Through walls/attics – Cleanest look, professional finish

Along baseboards or corners – Easier DIY, use cable clips

Through existing conduits – If available

Important:

Maximum cable length: 100 meters (328 feet)

Keep cables away from high-voltage electrical wires (to avoid interference)

Leave a little slack at both ends for easy adjustments

⏱️ Time: 10-20 minutes (depending on home layout)

Now it's time to bring everything together.

What to do:

1. Plug the Ethernet cable from each camera directly into a PoE port on the back of your ZOSI NVR
2. Connect the NVR to your router (using a separate Ethernet cable)
3. Plug the NVR into power
4. Connect a monitor to the NVR via HDMI or VGA
5. Power on the NVR

What happens next:
The NVR will automatically detect each camera. Within 30-60 seconds, you should see live video from all connected cameras on the monitor.

⏱️ Time: 5 minutes

The final step is to customize your system and connect it to your phone.

On the NVR (using the monitor):

Set admin password (write it down!)

Format the hard drive (for recording)

Adjust recording schedule (24/7 continuous or motion-only)

Configure motion detection zones (optional)

On your smartphone (ZOSI App):

Download the ZOSI app from App Store (iOS) or Google Play (Android)

Create a ZOSI account

Tap "Add Device" and scan the QR code on your NVR

Follow in-app instructions to complete setup

Test remote viewing by checking your cameras from anywhere

Congratulations! Your ZOSI PoE system is now fully installed and ready to protect your home 24/7.

⏱️ Time: 10 minutes

Yes, 4K refers to a resolution of 3840×2160 pixels (about 8.3 million pixels), which matches the 8MP (8 megapixels) specification commonly marked on cameras.

Not necessarily, but using a 4K-compatible display maximizes value. 4K PoE cameras will work with 1080p monitors, but the footage will be down scaled—you’ll lose the ultra-detailed 4K quality. For home or small business use, a standard 4K TV (3840×2160 resolution) works perfectly.

It depends on compression and setup, but rarely significantly. Zosi 4K PoE camera system use H.265+ compression, which cuts bandwidth usage by 50% compared to older H.264. For reference, a standard 100Mbps home internet plan can easily support 3-4 4K cameras. For larger systems (8+ cameras), connect the Zosi NVR to your router via Zosi PoE Switch, to avoid bottlenecks.

Match the switch to your camera count.

Small systems (1-4 cameras): Choose a switch with 4-8 ports.

Medium/large systems (5+ cameras): Choose a switch with 8-16 ports.

Calculate based on retention days and camera count

1 camera, 7 days: 420GB (60GB/day for 24/7 recording).

4 cameras, 14 days: 3TB (4×60GB×14 = 3360GB, rounded up to 4TB for safety).

8 cameras, 30 days: 8TB (8×60GB×30 = 14400GB).
