Ratings

We use the following ratings for many of the items below. CyberShack regards 70/100 as a pass mark. You can click on most images to enlarge them. We won’t rate it just yet, as it has only been bench tested.

Fail (below expectations), and we will let you know if this affects its use.
Pass(able) rating that is not as good as it should be.
Pass (meets expectations).
Pass ‘+’ rating to show it is good, but does not quite make it to Exceed
Exceed (surpasses expectations or is the class leader).

First Impression – Easy if you understand PTZ and NVR

Let’s explain a few terms because while this is a preliminary review, it’s also an exploratory to see what this does. We will revisit it as options become available and we move it from bench test to installation.

PoE

PoE means that you need an Ethernet cable capable of carrying both Ethernet and Digital audio and video (IEEE 802.3at and 802.3af up to 30W) for Cat 5 or 6 up to 100 metres.

There is a good overview of POE at D-Link DGS-1100-8PV2 8-port, PoE+ (Power over Ethernet) switch.

S4 Max PoE cam

Website

The S4 Max is revolutionary, combined 4K, 122° FOV, an ultrawide fixed Bullet camera and a dual 2K PTZ 360/70° and 8X zoom camera. That is three camera sensors, two Red/Blue LED warning lights and two LED spots to cover everything in auto-framing up to 50 metres away. It uses two channels per camera on the NVR.

It has Starlight colour night vision as well as IR night vision and AI colour vision.

You could replace several fixed cameras with a few of these and get better coverage.

4K Bullet: f1.6, Focal length: 2.8mm, Field of View: 123.3°（Horizon 105.4°, Vertical 58.8°）10°-40°
2 x 2K PTZ: fF1.6, Focal length: 2.8mm/8mm, Field of view: 117.1°/45°, Horizion 100.5°，Vertical 56.2° and Horizion 39.4°, Vertical 22.6. PTZ: 360° horizontal，0-70° vertical

Eufy currently has two other PoE cameras, including the E40 4K Bullet Cam and the E41 4K Turret Cam.

It also works with any Eufy Wi-Fi or HomeBase security cameras using the eufy Wi-Fi Module PN: T8709 (not yet released). This plugs into one of the NVR LAN ports, and each camera occupies one NVR IP channel. It also supports eufy IoT sensors.

Who is it for?

It requires Ethernet PoE-capable wiring so that it can be designed into new builds or retrofitted at a cost. This needs to run from the cameras to the NVR. It is a very advanced replacement for Wi-Fi cameras or smart hubs. There is no interoperability with existing HomeBases.

The NVR requires an Ethernet connection to the router, an HDMI monitor or TV, and the user interface is mouse-driven (supplied)
