The camera itself has been tested for several months, while the alerts have been tested for just over a month. The video quality is very nice, and the AI features work very well. In the first month of use, I have only experience 1 false notification for a person intruder. I have one of these set up watching my driveway with an intrusion zone set up for people. On the Synology NAS (DS1821+, I highly recommend this model) I have email alerts set up to my cell phone text address. I've tested it several ways, and it always positively detects people and vehicles entering my property while ignoring people and vehicles on the street, or in a neighbor's yard. I know when packages or pizza are being delivered before they get to the door. So far, no real intruders, but it has only been a month. It works equally well in day light, heavy rain, and at night. The price is reasonable, and the included license for the NAS is great. The time between detection and the alert on my phone is very fast. When walking to my car, the alert is going off before I open the door. When testing people detection only with vehicle detection turned off, I am alerted within seconds of opening my car and stepping out. Vehicle detection is also fast, but I was concentrating on people alerting as that was my bigger concern. I have not had issues in this neighborhood, but I did in another location I lived. I wish this had existed back then. Motion alerts were useless, and always going off. The people detection on this camera is great. I'm adding more of these, and replacing my other cameras with this model. If they ever make a PTZ model, I am buying several of those as well. I've been testing different surveillance options for our next move to the country, where we will have acres land to secure. This camera with it's price and features will be the primary workhorse for that location. Weather sealing works well, and this has survived several heavy storms. I do sometimes get false tamper alerts if the storm is very heavy with high wind. I am rarely this pleased with a product, but this camera is really great. For the images, I have provided two examples from one of my cameras. I have other overlapping cameras for full coverage. One area the camera could be better is distance resolution for license plates. However, the primary purpose for this model will be general recording and intrusion detection. I am auditioning some Axis cameras for license plate recording. Considering the price of those cameras, this one is very well priced, which is great as it will constitute the bulk of my fleet once we move.

This is a very capable NAS and a great value for the money. The short depth is great for tight racks/closets. Downsides include the lack of sfp ports straight out of the box and not enough ram. Lot of people complain about the noise, but I haven't had any problems with that or heat on quiet mode.

Compact and Configurable. Fans could be a bit quieter.

Works great! Instantly recognized by my DS1821+. No issues so far.

Bought this network interface card to add to my NAS to speed up file transfers so I can use it as a editing server. The card is super stable and has not dropped connection since I?ve installed everything. Definitely a great card to get your small business or home network attached storage device much faster for demanding file transfer tasks. I am using this with a Netgear 10gbE switch it works flawlessly

Great add on card to get full potential out of your Synology unit. Be sure to check compatibility before purchasing.
