Using tinyCam on Android for SecuritySpy

Leave a reply

While SecuritySpy has a dedicated iOS app that provides a great remote access experience on iPhones and iPads, we currently do not produce a dedicated Android app. This is because, since SecuritySpy is a macOS application, the vast majority of our users are within the Apple ecosystem, and very few use Android devices.

At this time, the best solution for viewing live video from your SecuritySpy system on an Android device is the tinyCam Monitor app. This app is inexpensive, easy to use, and has a built-in profile for SecuritySpy that helps to simplify the setup. Here’s how to set it up.

1. Set up access to your SecuritySpy system

If you need to access SecuritySpy only over your local network, all you need to do is to enable the HTTP web server under Settings > Web, and add a user account for password protection.

Additionally, for access over the Internet, follow the setup steps outlined here: SecuritySpy Installation Manual – Remote Access.

Your SecuritySpy server should now be set up for local and/or Internet access. Verify this by going to Settings > Web > Access Info; a panel pops up that shows access addresses for local and/or remote connections:SecuritySpy Access Info Continue reading →

AI-Powered Motion Detection

8 Replies

In our macOS CCTV software SecuritySpy, deciding whether to trigger recording and actions (e.g. notifications) is a two-step process. Firstly, a motion-detection algorithm determines whether there is some interesting movement happening. Next, the image is cropped to the area of movement and passed to a neural-network classifier to determine whether there is an object of interest present, like a human, vehicle or animal.

The classifier in SecuritySpy is based on a ResNet-50 neural network, custom-trained on over 100,000 real CCTV images from thousands of different cameras. It is a highly optimised, powerful network, producing very accurate results (around 97% for humans and vehicles).

In contrast, until now, the motion detection algorithm has been fairly simple. It has worked via pixel-based comparisons between successive video frames, with some additional filtering to help ignore extraneous movement caused by noise, transient motion and lighting changes.

This standard motion detection is fast and very effective in controlled environments that don’t suffer from a lot of extraneous motion. However, it is less effective in more challenging outdoor environments, where movement caused by shadows, swaying plants, snow, rain and so on can cause a high number of false-positive detections. In such situations, it maintains high sensitivity (ability to detect true motion when it occurs), but suffers from poor specificity (ability to accurately ignore extraneous movement).

SecuritySpy’s classifier is able to filter out virtually all these false-positives, however even if only 3% of false-positive detections get through the classifier, in particularly challenging situations where the motion detector is generating large numbers of false-positives, inevitably there will still be a significant number getting through and causing triggers.

Standard Motion Detection Pipeline

Replacing a Hardware NVR With SecuritySpy

Leave a reply

Want to switch from your current NVR to SecuritySpy? Hardware NVRs/DVRs can be limited, and their macOS software (like iVMS from Hikvision or SmartPPS from Dahua) often falls short. If your cameras support ONVIF or your NVR can produce RTSP streams, you can make the switch and gain all of SecuritySpy’s features while keeping your current cameras.

Your next steps depend on how your cameras are current connected – expand the section below that describes your current setup: Continue reading →

Using an iPhone or iPad as a CCTV Camera

Leave a reply

With the right app, an iPhone or iPad can make an effective security camera that provides standard RTSP video/audio feeds. This is especially useful for older iOS devices that would otherwise be unused, making for an easy and inexpensive way to add an extra camera to your video surveillance system built around our macOS NVR software SecuritySpy.

In order for an iOS device to be used for video surveillance, it should be powered all the time and set to never sleep. Such a device should never be used for a critical CCTV purpose, since things like power outages or app/devices crashes may require manual intervention to put right. This can be mitigated somewhat with Apple’s Guided Access or Single App features.

The following apps have been tested and confirmed to work well with SecuritySpy for H.264 RTSP streaming, delivering high-quality and efficient video/audio streams to SecuritySpy. Continue reading →

10 Recommended IP Cameras 2022

16 Replies

[Note: this list is now outdated – for our latest recommendations, please see Our Camera Picks]

Here are our network camera picks for 2022. 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 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 – very useful for easy setup.
  • IR – Infra-Red – some cameras include IR LEDs (Light Emitting Diodes) for night vision. Usually the manufacturer will specify the maximum useful range of the IR in meters (though this rating is sometimes overly optimistic).
  • Auto-iris – This allows the lens to automatically adjust its aperture based on light levels. 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. Generally, 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.

All “outdoor” cameras can be used indoors, however they tend to have larger form factors due to their waterproof housings. This isn’t always the case though – many of the cameras listed below are compact and absolutely suitable for both indoor and outdoor usage – we have marked these “indoor/outdoor”.

B&H Photo Video is a good source for buying cameras in the USA. Amazon is another option, however it lists many “grey market” products (e.g. those designed for the Chinese market but sold in the USA against the manufacturer’s rules), which should be avoided due to lack of manufacturer support.

We are not affiliated with any outlet or manufacturer mentioned on this page, and we get no financial incentive for recommending them.

BASIC INDOOR/OUTDOOR BULLET: DAHUA N42BD32

This is a basic, inexpensive outdoor camera with 4 MP resolution, good low-light performance, IR night-vision, and a compact form factor. It has a fixed 2.8mm lens, which produces a wide-angled view covering 102° horizontally. At only $100, this camera is great value and can make an effective addition to any CCTV system.

Offsite Backup of Recorded Camera Footage

6 Replies

Our macOS CCTV software SecuritySpy saves all recordings to a local drive. By default, the Mac’s internal drive is used, but you can specify any other drive(s) you want to use for this purpose, for example an external drive connected by USB or Thunderbolt or a NAS (Network Attached Storage) drive on the local network.

Modern drives are very reliable, and for most users the small chance of data loss due to drive failure may not be too concerning. However, this could be more of a concern for more critical commercial applications, plus there is also the possibility than an intruder could damage or steal the drive.

To minimise the chance of data loss, there are a few basic steps that users can take, for example by using only high-quality drives from reputable manufacturers, securing drives with anti-theft devices, or using multi-disk RAID disk setups that provide fault-tolerance.

One further method to prevent data loss is to set up automatic offsite backup for the most important captured footage, so that this can be retrieved if the primary storage drive is compromised. There are a few ways to do this: Continue reading →

Dahua IPC-HDW5831R-ZE IP Camera Review

3 Replies

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

Leave a reply

[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.
