THIS IS NOT A SEGURITY CAMARA, motion sensor is VERY SLOW and it can not be more sensitive. it takes about 5 second to begin recording.

This camera does not have so many features, unlike the ones that a real 'pro' on digital camera is looking for. It is not overpriced and the quality is not the best but I'd say very good. It does not come with a leather case because you don't need one. The lcd display has a thick protective glass like a scratchproof material (just don't drop it for a test or something). It is so small that's why it's called portable. If you have big hands naturally this is not for you. All digital cameras have different features of their own, you just have to read the manual to be able to appreciate fully what you got.

This is a great camera during the day, but the night feature doesn't work through a screen. All it records is a glare on the screen. My windows are full screened since they open top down as well, so unless I put it outside, where it can easily get stolen, it's useless at night.

This is a basic camera.  It's very small and compact.  The one thing I do not like about it, however, is that it doesn't have the infrared lights like most of them do to improve visibility in low light conditions.  It's relatively clear, though.  It helps that I have LED reverse lights, so I can't speak for how well they'd work under normal circumstances.

It's an OK camera. It's not really a night camera, you can only see for 20-40 min past sunset, and it dos not have WDR. So, it's pretty crappy during the day time, and just a little better than an HS1177 at night. It's smaller though, so that's something, I guess.

Nice camera. I like the battery life. Day pics are great, but night pics are way over exposed. Deer  show up as white with no definition.

This camera offers descent point and shoot type video.  If you're interested in making independent films, I would stay away from this camera.  For one, there is ONLY ONE CCD.  The camera CAN'T shoot in 24p progressive video mode, you're stuck with lame 29.97fps.  That means you'll never get that "film-like" feel that film-movie cameras have.  There isn't a manual focus ring, you have to focus using MENU controls!  The camera also has a CCD the 1/5.5" in size.  This pales incomparison to other cameras with bigger CCDs (like the sony fx1 with 1/3" CCDs).  A bigger CCD means better low light capability.  Also the max verticle lines of resolution is 520 lines.  This camera can't compete with 1080i type cameras that have over TWICE the verticle lines.  But it's a good camera for those who can't (or don't want to) spend $40K on a professional digital camera.  So don't buy this camera if you're interested in making professional feature films.

I had high hopes for this camera given the reviews but it fell short. The motion detection is not up to par. I was in my basement and it only took a picture of me once for over an hour. Also, the two way audio does not work especially from the camera side so I can't use it for baby sitting. For the price, if you want to view only, then you are good.

The quality of the camera is poor. They screwed up with the lenses.
The source of light is not great.
It might be useful in other areas but not in entomology.

Well made camera, but useless...

You cannot save the video in remote location.. only can save in the camera SD.. so if a robbery stole the camera, you don't know who the robbery is..

This is not an IP camera, this is an mobile camera.. this is not accessible from any computers.. only mobile phones can access the camera..

There is no credential to access camera.. this means you don't know that Xiaomi is maybe watching you, or the camera can be exposed to the public easily...

Use this camera for baby sitting and inside your home.. this cannot be a security surveillance purpose...

I needed a camera that would show outdoor activities around the house at night.  I did not realize that this camera would not do that.  The camera itself is fine.  I don't want to pay $400 or $500 for one that meets my needs.

This camara is NOT audio enabled. Deceptive product description. Also, the picture states that it comes with and audio/video cord when it is ONLY A VIDEO CORD. Plus apparently it is also only for indoors. DO NOT BUY.

It isn't very good quality. In a room with low lighting you get a very dark screen, can't really see anything. Same if you want to film outside at night. The light on the front really doesn't do much to help illuminate objects. Not at all what I expected from a camcorder. I will be buying a better model soon!

It's a kid's camera.  I wouldn't order it again.  You can only take photos in bright light.  For the price they could have made it better.

IMPORTANT NOTE: At the time this review was written the product description contained an error (that the camera has a 3x optical zoom). Of the millions of products Amazon sells mistakes like that can happen but it is an important spec for anyone interested in purchasing this camera. The error has been reported and this paragraph will be removed once the description is accurate. However, the simple typo does not affect the star rating this product will be given in this review.

Unfortunately, the erroneous spec is an important one. The category of security cameras can be divided into two broad sub-categories  cameras that will be manually operated by security personnel in a live surveillance environment;  and cameras that will be used 24/7 to monitor an unattended environment. This difference is important because in the first instance it is generally assumed that the environment being viewed will be under people conditions, in other words some place like a fully-lit retail store, workplace, storage area, etc. The operator would have control of the camera and would manually pan, tilt and zoom as needed to detect suspicious activity.  This camera does not have a zoom function.  A surveillance camera that doesnt zoom is significantly less effective for its intended use because by design a PTZ camera is intended for live monitoring and if the operator cant zoom in on the action they are left at a severe disadvantage. This is something that needs to be carefully considered by the customer noting that there ARE situations in which panning and tilting would be the only movement necessary, perhaps as in monitoring a cash register. Given the option, however, adding zoom for the nominal cost is well worth it.

On the other hand, security cameras intended for 24/7 monitoring are generally unattended, which negates the need for pan, tilt or zoom. These cameras are usually fix-mounted and attached to a recording and/or alarm system. Being unattended, there is no need to control the movement of the camera.

The other (in our opinion) significant drawback to this camera is that it has no IR illuminators, in other words, no night vision capabilities. Going back to the first scenario, most PTZ cameras that are controlled by security personnel are used in store-lit conditions and low-light capability isn't important. But a security camera that cant be used at night has virtually no value as a 24/7 security camera as it must be used in daytime-only live monitoring.

Knowing upfront that this camera does not have zoom capability nor does it have night vision puts it in the category of being a limited application device. For someone who is looking for a daylight-only camera that can pan and tilt but not zoom they will find that the quality of construction and image quality of this camera are a bit above average (Q-See has built a decent reputation for that), and they will find that the price is reasonable but a bit higher than some competitive models.

Because it does what it is intended to do, and does it well it earns a positive rating IF you don't need zoom or night-vision. Its not significantly better than other brands that offer the same features, often for less money, and therefore the final rating is I like it, which Amazon defines as 4-stars.
