EZViz C4W Review

A robust and tough indoor/outoor camera, the EZViz C4W has decent image quality but the fiddly app and installation let it down.


With its robust body that's easy to angle where you want it, the EZViz C4W makes it easy to get the coverage that you want. Its 1080p image sensor provides decent image quality in the day and night, and it's nice to see the option for offline SD card storage. Comparatively high cloud storage prices combined with a very fiddly app that makes it hard to get at the main options takes the shine off somewhat.


  • Flexible mount
  • Dual power options
  • Reliable image quality


  • Only Ethernet has a weatherproof connector
  • Fiddly app
  • Cloud storage is comparatively expensive

With its domed body, the EZViz C4W is an indoor/outdoor security camera that’s been built to be easy to place and point.

It’s rugged, well built and has excellent image quality. Slightly fiddly installation and a rather feature-free app do detract from what could have been a better product, though.

EZViz C4W – What you need to know

  • Installation – Options for wall or ceiling mounting but external installation could be made easier.
  • Detection performance – Difficult to find the activity zone settings, but once you do the camera is reliable and doesn’t generate too many false positives.
  • Image quality – Decent image quality close up but the image gets softer the more into the background that you go.

EZViz C4W Design and installation – Highly adjustable but weatherproof installation options are limited

The EZViz C4W is fitted into a secure, weatherproof dome box, which gives you rotation and up/down adjustment of the main camera. It’s fitted to a mounting plate, which can be attached to a wall or ceiling, either inside or out.

With the range of movement available to the camera, it’s easy to position it where you want the lens to point. And, as the camera can’t easily be removed, you get a secure connection that makes it hard for the EZViz C4W to be knocked off alignment.

There are two power cables coming from the camera. The first is a regular power input, with a lengthy extension cable provided in the box, running to the supplied power supply.

The second is an Ethernet input, which can provide power and data. However, there’s no Power over Ethernet (PoE) adaptor in the box, so you’ll need to provide you own.

EZViz C4W power connectors

You can run the power cables through the back of the mount, straight into your home if you want to drill a hole. If you can’t do this and have to run the cables externally, EZViz provides a weatherproof connector for the Ethernet connection only. This is a real pain, as other external cameras that I’ve reviewed have all come with suitable instructions and kit for the provided power supply.

As well as Ethernet, the C4W has integrated 2.4GHz Wi-Fi, so you can run it without cables if you prefer.

EZViz C4W Features – A very fiddly and confusing app

Once the C4W is installed, it’s controlled through the EZViz app, which is one of the most fiddly and hard-to-understand that I’ve ever used. When you first launch it, you get a thumbnail view of your camera that you can tap to view the live feed.

Depending on how you’ve installed the camera, you may find that the image is upside down. There’s an option in the Setting menu to flip the image, but there’s no preview to show you which way round the video footage is.

From here, you can use the two-way speak option to have a clear conversation with anyone that you can see on the feed; you can take a snapshot or record a video; and you can set off the camera alarm, which plays a rather quiet siren noise through the camera’s speaker.

EZViz C4W camera controls

At this point, there’s no motion detection notification. To change this manually, the easiest way is to go back to the main home screen and select Leaving-Home Mode to set the camera to notify you of motion; when you don’t want alerts, you select At-Home Mode. Sadly, the app gives you no feedback, so you can’t tell by looking which mode you’re in, which is a huge oversight.

You can also turn on Alarm Notification mode in the settings, which toggles alerts on and off. It’s probably easier to use the schedule option to have the camera automatically change notification mode.

By default, the camera uses its entire field of view to detect motion. If you want to focus on an area, you can select the bits of the picture you want to monitor. Well, you can do if the Alarm Notification mode is turned on, either in the Settings menu or by using the Leaving-Home Mode; if you don’t, then Motion Detection Area option doesn’t appear in the app. It took me a good 30 minutes of head-scratching, Googling and manual reading to work out where this option was.

Activity zones are basic but they do let you cut out areas that would trigger a lot of alerts, cutting down on the notifications you get. You can also set a schedule for notifications, choosing times when you do and don’t want to receive them.

As well as notifying you, you can have the EZViz C4W play a custom sound when motion is detected, recording your own voice. I can see where this might be useful, say warning someone away from a bike shed, but you need to be careful where you place the camera and how often is picks up motion: you don’t want to annoy neighbours by constantly having your camera shout out a warning.

Video can be recorded to an SD card (not provided) that fits into the screw-down hatch in the underside of the camera, or to the cloud. Cloud plans are fairly expensive at £4.99 a month (£49.99 a year) for seven-day history for one camera; plans for four cameras are £7.49 a month (£74.99 a year). Nest is cheaper at £5 a month for 30-day history for unlimited cameras, and Ring is £8 a month for all of your cameras with 30-day history plus some additional features for the Ring Alarm.

All footage can be viewed in the app, with neat thumbnails making it quick and easy to find the clip that you want. All clips can be downloaded and saved to your phone if you want to preserve evidence.

EZViz C4W Video quality – Good all-round but the image gets a touch soft into the background

Video quality is generally very good thanks to the 1080p video sensor. There’s a 118-degree lens on the front, which captures most of a room, if used inside, but you get a slightly narrower field of view outside than on competing cameras.

Using during the day, the footage is well exposed, and objects close to the lens are sharp and detailed, so you can see details and spot an individual easily. As you move into the background, the picture becomes soft, and the camera let some details slip into shadow, which was a shame.

At night, the camera has to switch to black and white using its IR LEDs to light up the night. The picture is softer overall, but close-up you can still spot individuals easily enough. As you move into the background, the image gets noticeably softer and you lose some details to shadow.

Overall, image quality is acceptable and clear enough to show what was going on but I’ve seen far better results from other cameras.

Should you buy the EZViz C4W?

From a hardware and video quality perspective, there’s a lot to like about the EZViz C4W: it’s robust and shoots decent video at a Full HD resolution. It’s the details that let the side down, with a fiddly and often confusing app making it hard to control the camera, relatively expensive cloud storage (although SD card storage gives you a free option) and slightly annoying installation with only weatherproofing for the Ethernet option.

The Ring Stick Up Cam is cheaper and better, and works out even better value if you have multiple cameras on a single cloud plan.
