This flash was introduced recently for the mirror less EOS M compact line of cameras Canon started in late 2012.However, the flash works with all other Canon cameras with a hotshoe. With pre EX series flash cameras, you lose some critical capabilities for correct exposure, like ETTL, or the II version thereof.However, with cameras with exterior speedlite control (please look up your cameras manual) you gain the ability to control off camera flashes through optical (using light/from flash as opposed to radio, like cell phones) signals. This is the least expensive solution from Canon for this off camera flash control from a compatible camera. Only the Canon 7D (and 60D) have built-in flashes that do this and none the full frame cameras even have built-in flashes. This tiny flash can control several off camera flashes in separate groups A, B, C and vary the ratio of light the groups throw out all using ETTL II within its limited 15~20 ft range!Also helps focus assist cameras in low light levels using light bursts, though this can be turned off. Just don't expect it to light up group photos outdoors outside its range. At best, use it as a fill flash on its own outdoors.

I shopped extensively for affordable wireless cameras and chose Dzees 2K. Bottom line: I couldn't be happier and highly recommend them to anyone. Set up was easy and the cameras connected immediately to my home network. Once established, the camera provided crystal clear imagery both in daytime and infrared modes. I appreciate that the phone app is intuitive and that that the battery life is displayed. I've had my cameras in place for about ten days now in high traffic areas and they are still at 100% battery capacity even in the cold winter environment. Although I own much more expensive cameras, I will be a repeat Dzees customer for future purchases.

I've had 3 different xmarto NVRs and multiple types of cameras. It's an easy system to use, my only complaint is the night vision IR lights are flaky. The new system is awesome with the Dream Liner relay, but we'll have to see how the IR does on these cameras.

Set up easy, visual, on point. The only issue I have was not knowing about using a USB for recording. When I ordered both cameras a purchase of a USB did not pop up as a suggested purchase. $120 a year for multiple cameras is 4 times more than my other subscription.

So... These cameras work, BUT, there are some things to consider:1 - The time and date on the cameras WILL NOT update properly if your internet connection is poor. My cameras currently show the timestamp from the 21st of June (6 days ago), and not today. Even though it is still recording in real time.2 - If you go around your cameras a lot, they will go off A LOT, regardless of the motion detecting or any other settings. This is good, but, gets rather annoying if you have your phone on you, and suddenly get 20+ notifications because the camera detects every little movement that you make and notifies you.3 - These cameras need to be charged. They do not take batteries. You plug them in and charge them. So far, my batteries last about 2+ weeks if there is nothing to detect. The simple recording live feed does not take much battery life at all. It is when it detects motion that the battery begins to be used a lot.Overall, for the price, these cameras are worth it if you need a simple security system to detect motion and alert you of anything suspicious. It has great options and they can be placed just about anywhere.

It literally only took us 30 minutes from start to finish to put up and connect 2 outdoor cameras and 2 indoor cameras. So far so good--like all things still in the tweaking stage getting motion notifications for the flag moving on the flag pole--easy fix in settings!

I now have 4 of these cameras posted at my construction sites. They're easy to set up and work great! I live on the west coast of Florida and the cameras not only survived hurricane Ian, but also allowed me to monitor my jobsites remotely during the storm. Highly recommended!

The item came in great packaging. During the 5hr wedding shoot, the dual cameras I used felt waitless. I adjusted my harness a little tighter than the example pictures as it gave me more ability to move around without the cameras swinging around too much.
