### 4/5 — Good cams

*2026-08-12, version 1.1.45*

Good cameras they do the job

### 1/5 — Will not load

*2026-05-08, version 1.1.38*

An update was performed yesterday and now I am unable to open the current view. Every time I try to open it, the app closes on me. I am unhappy with this development. Especially since I paid for the year fee.

### 5/5 — To what some say the cams are amazing and it never offers a seven day trial so that’s false

*2026-05-07, version 1.1.38*

I have 5 cams and not once has it put me in a trial…the user that said this is lying

### 1/5 — apps not after one year using.

*2026-05-07, version 1.1.38*

My app giving notifications for moving objects but when i try to open its just shut off by itself. I am so confused and frustrated.

### 1/5 — Update problem

*2026-05-06, version 1.1.38*

Was working very good then this latest update came out every time I try to pull up cameras it shuts the app down,  yes I restarted camera yes i check for updates,  yes I rest phone

### 5/5 — Camera & app

*2026-04-30, version 1.1.37*

We love the security camera & the app. We have the 360 camera and the quality is great. The subscription price is great & the customer service is great also. The app is very easy to use along with setting up the camera

### 2/5 — Sometimes you can actually see events

*2026-04-23, version 1.1.37*

Eh it's just alright. Sometimes it works. Sometimes it doesn't. Like right now I can't even see my recorded events. It's also a slow build to get the camera warmed up to see what's actually going on. The charge on the camera box lasts about a day and a half. Would I buy these cameras again instead of going to with a different system? Likely not.

### 3/5 — Easy set up!

*2026-04-06, version 1.1.37*

The set up for the app was very easy. Navigating and use is equally good but the playback has some lag. Overall a great value when you consider the price!

### 5/5 — Great for cottage security

*2025-11-24, version 1.1.29*

I have purchased to install at my cottage mostly for période of the year that we go as often  and are able to check on the place.  This is work perfectly and provide a sens of security  of your belongings

### 1/5 — Terrible app for mediocre camera

*2025-11-23, version 1.1.29*

Hate this app. When setting up a new camera, it prompts you to name it. The keyboard covers the “OK” button, so you can’t advance. Nothing will make the keyboard go away. Likewise, try to delete a camera, and you can see the delete link, but cant pull it up far enough to press.  
Added an SD card, and it wont record without paid subscription for EACH camera. Just terrible all around.
