Very good for its price, I have been using it for more than a month and I am satisfied. I remove one star because sometimes when your phone is locked, it takes a while for the notification to come that someone is in front of the camera "eye", but otherwise it works very well and the battery life seems satisfactory.

It was installed on a front door due to the lack of an intercom and wiring. So far, the impressions are very positive, it has a pretty good image and the infrared works perfectly at night. It has several settings for customization according to each user's preferences and the battery seems to have satisfactory performance. However, only time will tell about its durability in different weather conditions.

Oh my god! worth every penny! Our door doesn't have a peephole, so it was exactly what we needed. The highlights are:
- it triggers an "alarm" if someone tries to remove it from its case (which is almost wedged in, so don't worry that someone will remove it without triggering the alarm),
- battery durability of a week+ with day and night use, and
- it provides two voice alteration modes to answer calls (the "uncle" mode which is deep and bassy as if you're the blessed one from Kalimera Zoi tou Foskolou, and the "funny" mode which is a high-pitched voice).

It sticks and adheres, and for the curious rental owners, I guarantee from experience that it comes off WITHOUT DAMAGING THE DOOR (given that a hairdryer was used to warm up the glue).

I have had it for 2 weeks. For its price, it is excellent. The image is very good and it provides 3 days of free cloud recording. The battery, after the first charge and in power saving mode (activated only with motion or doorbell ringing), is still at 94%. Definitely value for money.

EDIT: In standby mode, the battery lasted nearly 3 months before needing a charge. It continues to work without any problems.
