Reolink Duo Review 1 scaled

Any links to online stores should be assumed to be affiliates. The company or PR agency provides all or most review samples. They have no control over my content, and I provide my honest opinion.

I have covered a lot of home surveillance technology over the years. One of the best advancements in this technology has been the introduction of object detection. Cameras are able to identify the difference between a randomly moving object, people, vehicles and sometimes even faces, pets and packages.

For an outdoor camera, I find this feature absolutely essential. The older style of general motion detection used to trigger an insane number of alerts due to shadows, rain or leaves and bushes blowing around in the wind.

The quality of the object detection varies between brands, and I am not 100% sure how each brand does things, but I think some cameras do the processing onboard while others offload it a server.  

For this post, I am focussing on wired POE cameras. I will do separate posts of battery-powered cameras

So, what are the best options when installing a new POE camera?

It depends on your NVR / Storage

All my recommendations for these POE cameras are based on the built-in functionality of the camera itself and the NVRs that the company produces. Many of them have microSD slots, and the motion-triggered events can be recorded to them instead of an NVR.

However, if you have a DIY network video recording running Blue Iris or other software, you will bypass the smart functionality of these cameras and have the NVR application handle everything. For Blue Iris, they have Smart Sentry AI, which is a paid service, or there is also DeepStack AI.

I have not used DeepStack AI, but it appears to offer superb performance and includes face detection. I used Smart Sentry AI, which sends a single image to a server for processing and the overall performance was excellent for my needs.

From my experience, this method of person detection provides the best performance. However, the cost of running an NVR/server needs to be factored in, especially with rising electricity costs.


ANNKE C800 vs Reolink

All the wired POE cameras Reolink have launched in the past couple of years feature person detection and vehicle detection. They release so many cameras it is there are probably too many to list, but any camera that ends in “A” has this feature. This includes:

The leading number indicates the resolution, either 5MP, 8MP or 12MP.

All the cameras are affordable, so I personally don’t see the need to use the 5MP option unless you are on a really tight budget.

I also wouldn’t get a camera without a spotlight. None of the Reolink cameras does native colour night time recordings, they need the spotlight to provide this. The ones without a spotlight record in B&W, the footage is perfectly good quality, but you don’t get the same sort of detail as colour provides.

With cameras without a spotlight and 5MP ruled out that leaves:

  • RLC-811A
  • RLC-812A
  • RLC-823A

Out of those, the main things to consider are the viewing angles and the overall dimensions of the unit.

I’d use the RLC-823a for all my cameras if it wasn’t for the fact it is absolutely gigantic (and also quite expensive).

The RLC-811A is probably my favourite all-around camera, but even that is physically quite large. This model benefits from 8MP, a spotlight, 5x optical zoom and good viewing angles when zoomed out.

Reolink Duo

An alternative option would be the Reolink Duo. This basically has two cameras built-in pointing at different angles. Each camera is only 5MP, but you get a massive 150-degree viewing angle.

Hikvision, Ezviz & Other brands

Hikvision doesn’t technically sell to the consumer, but the cameras are reasonably easy to get hold of, you may need to jump through a few hoops, though.

 From my experience, these provide much better image quality than Reolink, and the ColorVu camera delivers bright colour images any time of day. The downside is that they cost much more. There are also Darkfighter branded cameras, these provide B&W night footage but can provide clear images in exceptionally dark scenarios.

As for object detection, you want an AcuSense branded camera.

The cheapest ColorVu AcuSense camera I can find is the Hikvision DS-2CD2087G2-LU 8MP mini bullet for around £170.


Annke is either a subbrand of Hikvision or uses white-label Hikvision hardware, which is the same difference as far as the end-user is concerned. They have a lot of attractively priced cameras, and I have been impressed when I have reviewed them before

I think the N branded cameras are the models with AI human detection, these are not very cheap, but they should be good quality. The Annke NC800 is the perhaps the best option for £189/199 depending on dome or bullet. It is an 8MP camera, colour night vision, and has human/person detection. The lens is also 2.8mm so you have a wide viewing angle.


I haven’t reviewed any Lorex hardware, but they have a large 8-camera system that’s worth considering. The cameras have spotlights built-in for colour night vision, and the system has full person/vehicle detection. The included NVR has built-in POE ports, so it should be relatively easy to set up.

    1. Hi there.
      Very interested in your review.
      Decided to use top brand HIKVISION but let down with constant false alarms and equipment that does not seem to work.
      Just need a 4 camera system that purely does human and vehicle intrusion.
      Can you please advise if possible if there is anything out there without constant false alarms.
      Thank you.

      1. The most reliable option is likely to be using NVR software such as Blue Iris and then either using Sentry AI or Deepstack. I have written about Sentry AI before but Deepstack now seems to be the best solution. This can do facial detection as well as person and vehicle.

        I stopped using my one Hikvision camera in favour of running all Reolink cameras. I have found them to be quite reliable with human detection but I have activity zones set up and I only have a few events each day, it might be different for busier environments
