The IP camera market is replete with bullet-style cameras, with Dahua Technology being one of the major manufacturers of cameras of this type. Basic Dahua bullet cameras are well-designed, inexpensive, and generally provide good quality video, however it doesn’t cost too much more to get a model like this one, which has some key features that allow it to perform much better than basic models.

Dahua IPC-HDW5831R-ZE IP Camera Review
Dahua Technology have such an extensive range of IP cameras that it can be difficult to choose between them, especially between models that are superficially similar. Generally, Dahua cameras work very well with our macOS CCTV software SecuritySpy, and this particular model, the IPC-HDW5831R-ZE, looks like it could be something special.
This is an “eyeball” type camera, which is a form factor with some significant advantages: they are generally compact in size, easy to swivel and rotate to the correct position, and, unlike dome cameras, there is no curved perspex dome in front of the lens to reduce quality.
AXIS A8105-E Video Door Station Review
[Update July 2024: Axis has a newer video doorbell, the I8116-E, which is an improved version of the model described below.]
Video doorbells are becoming increasingly popular, and have the potential to make a useful addition to any CCTV system. Our macOS CCTV software SecuritySpy works with many different video doorbells, but choosing one to use can be difficult, as they vary significantly in terms of feature set, quality, reliability and cost. In addition, many video doorbells (e.g. Ring, Nest, Eufy) are designed as closed cloud-based systems that lock you into a subscription, and specifically don’t work with NVR (Network Video Recorder) software such as SecuritySpy.
Features
The Axis A8105-E doorbell offers a good all-round feature set, including 2 MP resolution, Power-over-Ethernet, two-way audio, compact design, and multiple input/output ports to connect accessories such as chimes and door openers. A 1.56mm lens provides an outstandingly wide 180º horizontal field of view and the ability to capture people very close to the camera.
10 Recommended IP Cameras 2021
[Note: this list is now outdated – for our latest recommendations, please see Our Camera Picks]
Here are our network camera picks for 2021. They are listed in no particular order (they are quite varied in terms of cost and feature set, which makes them difficult to rank as a “top 10″ list), however they are all cameras that, due to their impressive features, we recommend to our customers for use with our SecuritySpy CCTV software for the Mac.
Some abbreviations used below are as follows:
- MP – Megapixel resolution – the number of millions of pixels in the image sensor. The higher the resolution, the more detailed the image, but resolution isn’t everything: the optical quality of the lens system is also extremely important.
- PoE – Power-over-Ethernet – when using a PoE switch, the camera draws power over the ethernet cable and so doesn’t require a separate power supply.
- IR – Infra-Red – some cameras include Infra-Red LEDs (Light Emitting Diodes) for night vision. Usually the manufacturer will specify the maximum useful range of the IR in meters.
- P-Iris / DC-Iris – These features (collectively called “auto-iris”) allow the camera lens to automatically adjust its aperture based on the amount of incoming light. P-Iris is more sophisticated and will give better results than than DC-Iris, but both are far better than a Fixed-Iris lens, especially for outdoor applications.
- Varifocal – These lenses allow you to adjust the field of view at installation time. A focal length of 2.8mm is wide-angle; 4mm is medium; 8mm is moderately telephoto (a bit “zoomed in”). This is not the same as true “zoom” lenses: varifocal lenses are designed to be set once at install time, whereas zoom lenses are designed to be operated continually.
- PTZ – Pan/Tilt/Zoom – motorised remote control of the camera’s horizontal and vertical angle and focal length.
For purchasing IP cameras, we recommend B&H Photo Video – they are a reliable, established outlet. Amazon is another option, however there are many “grey market” cameras sold on Amazon (e.g. cameras designed for the Chinese market only, but sold into the US against the manufacturer’s rules), which should be avoided due to lack of support from the manufacturer.
We are not affiliated with any outlet or manufacturer mentioned on this page, and we get no financial incentive for recommending them.

10 Recommended IP Cameras 2020
Here are our network camera picks for 2020. They are listed in no particular order (they are quite varied in terms of cost and feature set, which makes them difficult to rank as a “top 10″ list), however they are all cameras that, due to their impressive features, we recommend to our customers for use with our SecuritySpy CCTV software for the Mac.

- PoE – Power-over-Ethernet – when using a PoE switch, the camera draws power over the ethernet cable and therefore doesn’t require a separate power supply. This is very useful for easy installation and ongoing reliability. All the wired Ethernet (i.e. non-WiFi) cameras on this list support PoE, but note that the larger “speed dome” cameras typically require the higher-powered PoE+ standard.
- IR – Infra-Red – some cameras include Infra-Red LEDs (Light Emitting Diodes) for night vision. Usually the manufacturer will specify the maximum useful range of the IR in meters.
- P-Iris / DC-Iris – These features allow the camera lens to automatically adjust its aperture size, based on the amount of incoming light. P-Iris is more sophisticated and will give better results than than DC-Iris, but both are far better than a Fixed-Iris lens, especially for outdoor applications.
- Varifocal – These lenses allow you to zoom in and out somewhat (sometimes manually, sometimes motorised), in order to adjust the field of view at installation time. A focal length of 2.8mm is very wide-angle; 4mm is standard; 8mm is moderately telephoto.
- PTZ – Pan, Tilt, Zoom – motorised remote control of the camera’s horizontal and vertical angle, and focal length.

Amazon is another option, however there are many “grey market” cameras sold on Amazon (e.g. cameras designed for the Chinese market only, but sold into the US against the manufacturer’s rules), which should be avoided due to potentially foreign-language user interfaces, lack of firmware upgrades, and lack of support from the manufacturer.
BASIC OUTDOOR DOME: DAHUA TECHNOLOGY N44BN52
This compact outdoor Dome camera from Dahua is a good inexpensive ($180) camera for covering an outdoor area. 4 MP resolution and good low-light sensitivity, combined with 20m night vision and a built-in microphone, provide all the basic features necessary to make an effective addition to any CCTV system. And it works in temperatures down to -40° C (–40° F), making it ideal for extreme environments. Continue reading

Network Topology
Overseeing a new installation of a video surveillance system recently gave me some useful insights into network hardware and layout. The system is relatively high-spec, using Arecont AV2100 and ACTi ACM-1231 megapixel network cameras, with a Mac Mini as the recording computer (running SecuritySpy of course!). If you are unfamiliar with Arecont, they produce simple box cameras with unparalleled visual quality. ACTi cameras were chosen for other areas because they offer additional features such as infrared night vision and audio.
