Dahua IPC-HFW2831T-ZAS Camera Review

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

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.

Setting Up A Home CCTV System

In this blog post, we will go through the process of setting up a video surveillance system for your home, based around our macOS CCTV software SecuritySpy. When setting up a home CCTV system, cost is an important consideration, but we also want to choose high-quality hardware that is easy to install and set up. To this end, our example system will comprise the following components:

Cameras: we have chosen to use Amcrest IP5M-T1179EW cameras for the following reasons:

  • Physically quite small and unobtrusive.
  • Easy plug-and-play setup (no manual IP/network setup required).
  • High resolution (5 MP), night vision, and good codec support (H.265 and AAC).
  • A built-in microphone – essential for a camera covering an entrance.
  • Great value – under US$70.

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.

Some abbreviations used below are as follows:

  • MP – Megapixels – the number of millions of pixels in the image sensor. The higher this number, 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 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.

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 potentially foreign-language user interfaces, lack of firmware upgrades, and lack of support from the manufacturer.

BASIC OUTDOOR DOME: DAHUA TECHNOLOGY N44BN52

Dahua Wedge Camera

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

Hikvision DS-2CD2432F-IW Camera Review

Hikvision is a big name in the IP camera industry, offering a wide range of cameras that cover the whole spectrum from small home-use cameras to professional high-resolution industrial models.

Features

The DS-2CD2432F-IW is an inexpensive ($130) compact camera suitable for indoor use, with an impressive feature set. The 3 MP sensor offers higher resolution than many competing products from other manufacturers (Hikvision themselves also produce a DS-2CD2412F-IW model with a lower 1.2 MP resolution, but the price difference is not large, so we we would recommend going for this 3 MP model). It has both WiFi and Ethernet connectivity, and can be powered either by PoE (Power-over-Ethernet) or by a 12v power adapter, making it easy to install in any network environment. The sensitivity of 0.07 Lux, combined with built-in infrared (IR) illumination, allows it to function well in low-light situations, and it has a built-in microphone and speaker for two-way audio.

Siselectron SCI1132 Camera Review

Siselectron Technology is a new player in the IP video security market, with a limited but impressive range of IP cameras designed for demanding applications.

Features

The SCI1132 is a box-type camera that is suitable for indoor usage, with some impressive features that you won’t easily find elsewhere. To start with, it has a built-in 3x zoom lens (3-9mm), which provides a very useful zoom range, from wide-angled to moderately telephoto. It has an impressive 4 MP resolution (twice the number of pixels as 1080p), and it can stream at its full resolution at up to 30fps. In addition, it has auto-focus (rather than the fixed-focus lenses found on lower-quality cameras) as well as an audio input (to be used with an external powered microphone), and power-over-ethernet.
