Excellent for the price. will see durability over the next few months. but love it so far

I like YoLuke IP cams a lot and have been using them for several years now. They hold up very well both indoors and outside and are very reasonably priced. These cams could easily be sold for twice the price, as a search for similar cams shows. The model P3-5MP-RWF is no different. This model is a pan tilt zoom (PTZ) cam with 4x powered optical zoom. Optical zoom means it is a true zoom lens camera like a photography camera and produces a much better image than digital zoom, which just uses software to expand part of the image with no increase in resolution. It can also be used with a memory card to store pictures and video which can then be accessed directly from the cam. No other equipment is necessary. I like these cams because they work with 3rd party software like iSpy. With some cams you have to pay for a subscription service to monitor your cams from the internet. These cams give you a choice between running your own server or paying for a service. This cam also does not have a blind spot which is nice. When set to rotate it covers all 360 degrees around the cam. The 5 Megapixel (MP) cam provides a resolution which is much higher than an HD cam, generating very clear pictures and video. It is a fine outdoor security cam (which is what I am using it for) and the night time infrared (IR) light emitting diodes (LED's) are super bright. I used to have to use a separate IR floodlight to get a clear view of my driveway with my old cams but this cam eliminates that. The mounting of this cam is not difficult. It can be attached to wood, brick or even concrete without a lot of trouble.

I got this to record video for my son's basketball game and daughters softball games.I set this up on a tripod and using the included remote I just turn it on and off as needed.You can also use the included app to record - and then you can see what is actually on screen. But I've found that using the remote is faster because the phone goes to sleep and I have to unlock it to start/stop recording. So better to use the built in remote.I'm very happy with the purchase. And I'm considering getting another one to record different angles.

The media could not be loaded.


















 Yi 4K Action CameraUPDATE:As noted below, after less than 48 hours with the camera, while videoing my daughter's volleyball, the camera, no a tripod, was struck and knocked to the concrete floor. As you can expect, it was damaged, breaking the corner off of the front cover (the one through which the lens extends, and containing the words "4K video recording...."I contacted customer support, and asked to purchase a replacement front cover. I was told that Yi did not have these available. However, after a few back-and-forth emails (see below), they did decide to replace the camera under warranty. They DID NOT HAVE TO DO THIS, and I ask you not to expect them to do this very often (YMMV).They then asked for my Amazon order number, which I provided. However, they responded that they could not locate that order number, and asked for screenshots of my Amazon order. I provided these, and they informed me that the company from which I purchased was not an authorized reseller of Yi products, so they could not honor the warranty. They suggested I return the camera to Amazon and then purchase from an authorized dealer.I bought this legitimately through Amazon, with this listing (and Amazon's Choice label), and through Amazon Prime ("Sold by Electronics Club and Fulfilled by Amazon."). I was understandably, none too pleased. I contacted Amazon, and complained that they had connected me to an unauthorized dealer, without letting me know, and to my surprise, they offered to refund my purchase. Since the damage to the camera was caused by me, I insisted that Amazon provide a note in writing that they would accept the return, and started the refund process with them.Yi had provided an Amazon link to connect me to an authorized dealer, but when I looked it was this same listing. I queried Yi about which of the companies connected to this listing were authorized, so that I could re-purchase the camera, while the refund was in process (I have more events to video nearly every week), but did not get a response within a couple of days. So I called Yi to see if I could get that list, and was told that they did not have that kind of a list in the support department. They told me that they could not connect me directly with the individual I was corresponding with, but that he was the only one with that information, and I would need to continue my email thread with him to get that list.Well, given the delay in response, and the ticking Amazon return timeline, that meant I could return the camera, but if I bought another before ensuring I purchased from the right vendor, I would risk not getting the warranty again. I emailed my Yi contact again, and finally received a response. Yi decided to honor the warranty anyway, and shipped me a replacement camera!I must say that, in the end, this was excellent customer service. They definitely went above-and-beyond for me personally. However, not knowing which of the vendors listed here are authorized is a problem. I wish I had gotten the list to share with you here.---- Original Review ----I've gone through several inexpensive action cameras, researching a lot, and ordering a few. I'll include other items I liked and didn't below, but the one thing I noticed with all these cameras is the inaccuracy of the advertised video modes, both in resolution and frame rate. The Yi 4K is about double the cost of the previous camera that claimed similar modes, but that camera didn't deliver. The Yi 4K is close enough for my purposes, but not quite perfect.As for resolution, those appear to be standard:4K/UHD is actually 3840x21602.7K is actually 2704x15201080p is 1920x1080, etc.But frame rate is a different matter. The attached video shows many of the modes:* The video itself is 4K/UHD @ 60 fps (although I don't know whether Amazon will scale it or change the frame rate). Each input video mode was scaled (by my editor) to 4K/UHD, for the duration of each 20 second segment.* In the lower right of the screen is the "name" of the video mode, (mostly) matching the designation on the camera (although modes with "Ultra" in the name were abbreviated to "U" to save screen space).* The source video timecode is overlaid on the lower left. This lets you compare the frame number to the frame contents. (Due to the design of my editing software's frame counter, I had to put the timecode on the left to chop off a bunch of extra, unimportant text.)* In the bottom middle is an indication of the actual recorded frame rate (the actual number of individual, unique frames recorded each second). This should not differ from the playback rate (except for designated "slow motion" modes). This text is also color coded to indicate whether the mode matches what is specified.* The frame rate of each input video was also scaled to match the 60 fps (actually 59.94, but that difference doesn't matter here) during the first 10 seconds of each segment. (e.g. the timecode would count from XX:00:00:00 to XX:00:00:29 during the first second of a 30 fps input video, and each time code would be shown twice to match the 60 fps output video.)* The second 10 seconds shows the video slowed down to 1 fps, to clearly show individual frames. Comparing the video to the timecode makes it obvious when a frame is replicated (timecode changes, but content of the image does not).* Further, (most of) the media info (obtained from Media Player Classic, using codecs installed with K-Lite CODEC Pack) is overlaid on the first 5 seconds. The important items to notice there are the video's resolution and frame rate, the latter being highlighted.* Finally, some segments include extra information overlaid on the video.Each video clip was recorded with most settings at defaults/auto (e.g. WB, ISO, etc.). The field of view (FOV) was set to maximum (Wide), except for the unconfigurable Ultra modes. The lens distortion was enabled for all modes that allowed it, which was mostly non-Ultra modes.With respect to the frame rates, what the video shows:"4K/30" - Recorded at 30 fps, played back at 30 fps. (GOOD)"2.7K/60" - Recorded at 60 fps, played back at 60 fps. (GOOD)"2.7K/30" - Recorded at 30 fps, played back at 30 fps. (GOOD)"1080p/120" - Recorded at 60 fps, played back at 120 fps, causing the clip play twice as fast and run for half as long as recorded. (BAD)"1080p Ultra/90" - Recorded at 45 fps, played back at 90 fps, with each frame repeated twice. (BAD)"1080p/60" - Recorded at 60 fps, played back at 60 fps. (GOOD)"1080p/30" - Recorded at 30 fps, played back at 30 fps. (GOOD)"720p Ultra/60" - Recorded at 60 fps, played back at 60 fps. (GOOD)"720p/120" - Recorded at 60 fps, played back at 120 fps, causing the clip play twice as fast and run for half as long as recorded. (BAD)"720p/240" - Recorded at 240 fps, played back at 240 fps, but the image is dark. (GOOD)That's much better than other cameras (7 of 10). The last one I tested was accurate (GOOD) only on 2 of 7 modes.The actual image quality of these modes will take some further testing to be thorough, but so far, it is fairly decent. Some other cameras used very poor methods of scaling the data from the sensor to the video resolution, resulting in immediately obvious poor quality (see Nearest Neighbor Scaling). But the Yi 4K scaling is pretty decent on first look. I'll have to break out the resolution chart to get any more detailed, but I haven't done that yet (and I'm not certain how that's going to work with such a wide angle camera, anyway).Beyond frame rate, here are some other Likes and Dislikes:Likes-----+ Most frame rates are as advertised (at least the ones that are critical to me).+ The individual files of long recordings, which are broken into ~3.8 GB h.264 files, are actually complete! This is not only the first action camera I've seen with this, but even my high end consumer video camcorders don't do this. They all require post-processing to join the files together (Google for AmateurResolveAndFusion), in order to avoid losing frames at the boundary, before loading the video into the editor. MANY KUDOS to Yi (or their silicon vendor) for this simple solution that saves a LOT of time!+ Camera includes lens distortion correction. Obviously, there is some loss of data at the edges of the picture, but the lines are straight! It's not perfect (objects at the sides of the screen are a bit wider than they are in the middle), but unless your video editor has this feature, it's great to have.+ Has built-in tripod mount, so no frame or case is needed (however, see last Dislike below).+ Mobile app (at least for Android -- Yi Action) is much better than the one used by other cameras (XDV).++ It doesn't crash (at least not yet).++ It will update the camera's firmware, so you don't have to load it onto a microSD card (I think you can do that as well, but this is easier).++ It reconnects with the camera well and fast, even after your phone goes into low power mode. (XDV usually requires killing the app, and often clearing the memory and starting from scratch.)++ It displays the video image correctly (a bit of glitch sometimes, but great for framing) after reconnecting. (XDV video is blank.)++ Has full controls for the camera. (XDV is limited.)++ Has short cut buttons, including lens correction.Dislikes--------- Not all frame rates are as advertised (see video).- 720p/240 image is dark, even with ISO at max (6400 -- see video).- Sound is poor. I haven't done much with sound (just noisy volleyball gym, so far), but what I've heard sounds pretty bad. There's distortion and buzzing, plus tons of noise. I did not include the audio with the sample video, but this was taken in a room where the only actual sound was a ticking clock, and the internal noise was so loud that the tick could not be heard on the recordings.- File naming, especially for 2nd and later files for long recordings (>3.8 GB) is very confusing (e.g. YDXJ0028.MP4, followed by YN010028.MP4 then YN020028.MP4).- Doesn’t do 4k Ultra (i.e. full wide angle) at 30 fps (only 24 fps)- No configurable/setable WB. Unfortunately, at least for the volleyball gyms I've used the Yi 4K in so far, none of the presets give anywhere near a decent picture. The Auto setting isn't too bad, but the nature of Auto is that it changes (not sure whether it will change during a recording, but definitely between recordings). So doing post-processing to correct the color means a different adjustment for every clip! A setting that allowed the camera to set the white balance while looking at something (in the middle of the screen) that is white, would at least let the color be consistent, allowing one adjustment (if necessary) to be used for all video clips.- Mobile app uses the same button to start/stop video. There is a delay, which seems to vary, so if you press the button, see that video hasn't started recording, then press it again, you are likely to have just stopped the video after it recorded only a few frames.- Doesn’t display correct field of view (FOV) on screen until the recording starts. The first time I tried this setting, I thought it didn't do anything. So I set my camera up to take in the whole volleyball court (using either the camera screen or the mobile app, it doesn't matter). But when I started the recording, suddenly the FOV changed! The lens distortion adjustment shows immediately, even if the video isn't being recorded, but not the FOV (Wide, Narrow, etc.).- The list of supported SD cards are too small and limiting. Not only does the list only contain the most expensive cards going, but the biggest cards on the list are 64 GB. I'm afraid to buy a 128 GB (expensive tier) card to see if it works. What about 256 GB? Yi could definitely help us out here by updating the list.- Connecting the Mobile app to the Yi 4K via WiFi disconnects you from any other data network. This means I don't get any app notifications, and can't access the internet, if I use this feature. (I realize this may be an Android limit with WiFi, but then I'd ask whether we can't use Bluetooth instead.)- No control over shutter speed in video mode. Again, with sports, I'd really like a faster shutter (I realize this will require increasing ISO) to freeze the ball better. The faster frame rate helps, but direct control would be preferable.- Does not take a fall unscathed. OK, well, this isn't fair. I video my daughter's volleyball games, and a ball ricocheted and hit the camera on the tripod, knocking it to the concrete floor. It was less than 48 hours old! (The sample videos were taken before this injury.) The corner of the front cover broke (plastic vs concrete). Otherwise, the camera works fine. I've now ordered and received an aluminum case (Amazon ID: B01LPWTX0E) to avoid further injury. (I looked for a replacement case or front cover, but so far, the only one I've been able to find has me concerned about whether giving my credit card information might be dangerous. Yi, if you're reading this, and you have an empty case, broken camera, or front cover lying around, I'd love to get one!)Maybe some of these Dislikes can be corrected with a firmware update. However, the Yi 4K is a 2017 model, and the newer (and double the price) Yi 4K+ is the top of the Yi line of action cameras, so I'm not sure how much work is still being done on this one.I still haven't tested other features of this camera, like EIS, YouTube streaming, time lapse, (don't care too much about voice control), etc. And I haven't really checked the battery life. I didn't buy an extra battery and charger, because I doubt even 2 would make it through one day of the volleyball tournaments (the longer they play, the better they are doing, so running out of power late might mean missing the championship game!). Instead, I've been using an external battery, connected via microUSB, to be sure the camera lasts all day.While not perfect, overall, the Yi 4K is very good. This one (unlike the last one) is definitely a keeper.

The XSi is my first DSLR camera. I have, for many years, been shooting with point-and-shoot (also called "compact") cameras, so I have a lot of experience with point-and-shoot cameras. But the image quality of the XSi simply blew me away! The images captured on the XSi are much, much, much sharper than the ones from a point-and-shoot camera!If you're looking at the XSi, you're probably a budding photographer like myself. The XSi is, debatably, the best entry-level DSLR camera, next to the

 alone sells for [...]. You have everything you need to get started right away with taking great-looking pictures!- Phenomenal ImagesAlas, I'm unable to show you the images I've captured with the XSi here. But there's alway sample images uploaded by customers on the product page. Alternatively, you can go to the Canon site and see for yourself the official sample images. These images are pretty representative of the quality of images you can expect from this camera in optimal conditions.- Auto ModeOkay, so you're not quite prepared to tinker with the bells and whistles on the XSi. No matter, there's always a fully "auto" mode (green rectangle on the selection dial) you can fall back on. In this mode, you would be using the XSi just as you would a point-and-shoot camera. The auto mode will stifle your creativity, but it will help you take great pictures nonetheless.- Incredible Battery LifeI must have taken hundreds of pictures of pictures and the battery indicator bar still shows full battery capacity (that's with image preview disabled- which is, if I'm not mistaken, the default/factory setting).In sum, the XSi does everything your point-and-shoot does, only BETTER.If, like lot of people, you are in a quandary deciding between the T1i and the Xsi/450D, here are the major improvements of the T1i over the XSi (at least on paper) to help you make a decision:- 15.1 MP Resolution- Full HD video at 20 Frames Per Second- ISO range of 100 to 3200- 920,000 dots VGA monitorvs. the XSi:- 12.2 MP Resolution- No video capability- ISO range of 100 to 1600- 230,000 dots VGA monitor* T1i vs XSi *- Resolution: 15.1 MP vs. 12.2 MPWhen it comes to megapixels (MP), I would have to subscribe to the mantra that megapixels isn't everything. Since the T1i has the same sensor size as the XSi (APS-C size: 22.2 x 14.8mm), a higher number of megapixels would mean more pixels packed into same sensor area.Keep in mind that as a general rule, the higher number of megapixels that are packed into a given sensor area, the more "noise" (or graniness) will result in a picture taken in low light conditions. (I want to be fair, however, and say that I have not noticed perceptible differences in image quality between the two cameras, even in moderately lit or low light conditions.)- HD VideoThe T1i frame rate is 20 frames per second (fps), which is low compared to even the low-end camcorders, most of which are capable of 30 fps in Full HD. The XSi has no video mode.- ISO: 3200 vs. 1600Like they say, there's no such thing as a free lunch. A higher ISO *will* result in more noise in a captured image. As a rule of thumb, set your ISO to the lowest practicable ISO setting. The lower upper range for the XSi isn't, in my opinion, a big restriction.- LCD Resolution: 920,000 vs 230,000 dotsThere is absolutely no refuting that the LCD on the T1i *is* better than the one on the XSi. The images displayed on the T1i LCD is unquestionably sharper than the images on the XSi LCD.Based on the above factors, you will have to be the one who ultimately decides what works better for you.There are, of course, other considerations, the most glaringly obviously of which is - you guessed it - the price. The price of the XSi is has dropped like a rock since I purchased it a couple of months back. If you're on a tight budget, the XSi is definitely the way to go.---The image quality from the XSi is simply phenomenal. It is very affordably priced (it has gotten much cheaper than what it sold for originally when it debuted in 2008). If you're on a budget, the XSi is, in my opinion, the best DSLR camera to get.

I love the camera! I have purchased the latest gopro for work and quite.honestly can not see a difference in video quality. Easy to use! Most importantly it was shipped without one of the parts. I contacted customer service and in less than 24 hours on a weekend they have shipped the replacement. All around great experience.l

Camera is more compact, and easier to use than my Eken H9/H9S, battery life at 4K H265 is better than the Eken at 1080p, It has a tally light on the rear, and the battery is super easy to access (eken often requires a tool if you're fingernails are soft from being in the water) touch screen isnt a super needed benifit, and i often found myself using the buttons, however it does make it faster to open the menu. Image quiality is a little better than my Eken, though this is probably due to the very similar lens quality, maybe better glass would result in better photos and video. The built in color filters are great for underwater video, but i never really got to test this feature(the main reason i bought this camera)While snorkling in a lake in Arkansas i noticed considerable condensation after a few minutes, I assumed this was because of the very humid air inside the case. then after about 40 minutes, there was about two eye drops worth of water inside the case, i checked the seals and buttons, no hair or dust, and all the water seems to have come from the bottom of the seal, i noticed the door sits farther away from the case at the bottom than at the top, about 1/16th of an inch, and IDK 2mm? water appeared to have come from the corner and center of this hinged seal, the door is harder to close than my Eken, which is good, i always though it was too weak. I cant speak to the rest of the accessories as i dont use them, but at first glance, they seem better constructed, the included ultra slim mount is a nice touch when you need to protect it from overheating more than bumps and water

Aurosports 10-30x40 Zoom Monocular (manual titled UltraZoom MegaZoom Pro). Measured: 154x50/44mm, 206gr, 241gr with caps and case. Comes with strap, lens caps, lens wipe, manual. Lightweight, clear view. Not small. Good field and light at lowest zoom, less so at higher zooms. Has screw hole for standard tripod. Tripod likely required at higher zooms to avoid shaking. Works with eye glasses. Has 4 controls: In the thin end is the eyepiece. Turning it does not seem to make much difference and is not mentioned in the manual btw. The ring next to the eyepiece is for setting the zoom level (may have to turn the eyepiece to unlock it). The remaining 2 controls are the extend/collapse of the barrel and turn of the barrel for approximate and fine focusing respectively. To adjust either do as the manual says (not sure it is not confused tho). Alternatively set the desired zoom. Lower zoom provides more light and wider field but less magnification and more shaking. Next, to focus hold the thin end of the barrel and turn the thick end to say around midway around the 10 mark leaving adjustment room to either side, extend/collapse the barrel until approximate focus is found and then again turn for fine adjustment. Guess the case is designed for the scopes thin end with its end cap at the bottom of the case and thick end with its end cap at the lid end as there is cut outs in the sides in the lid end for room for the big end cap. A keeper.
