Most Mac users have an old iPhone or two lying unused in a drawer. One great
way to repurpose these devices is to turn them into security cameras – all
you need is an app that does a good job of capturing and streaming video
from the iPhone’s camera. In this blog post we review a few such apps,
which work with our Mac NVR software SecuritySpy. To turn an iPhone into an
effective CCTV surveillance camera it should be permanently connected to a
power supply, and have access to a good WiFi signal for reliable
transmission.
wireless-camera-small1. Wireless Camera
This is a well-designed app that has some nice features, such as control
over the camera’s flash LED, a range of resolution options, and the ability
to switch between front-facing and rear-facing cameras. It’s very easy to
configure and provides good video quality – from 640×480 at 10fps to 1920
×1080 at 5fps.
Pros
Inexpensive ($1.99)
High resolution
Reasonably good performance
Cons
JPEG only (no H.264 encoding)
No audio
live-reporter-small2. Live-Reporter
This app encodes and streams in H.264 format, which has the advantages of a
much lower data rate than JPEG streaming; SecuritySpy will be able to
capture this H.264 video directly to captured movie files for efficient
storage. This also allows the app to stream video with impressive
performance – up to 30fps in 1920×1080 mode. There are also some nice
features such as authentication, date/time overlay and fine control over the
video encoding parameters. There is a free version, or a paid-for version
that removes advertisements and adds a few extra features such as
configuration of settings via the app’s web interface.
Pros
Inexpensive (free or $1.99)
Great feature set, including date/time overlay
Efficient H.264 streaming
High resolution
Good performance
Cons
Audio is one of this app’s features, but we couldn’t get it to work in our
testing
ipcamera-small3. iPCamera
This is a simple app that streams JPEG video with good performance. Its
maximum resolution is 1280×720, which is not as high as the above two apps,
but it is still reasonably good for general-purpose video surveillance. At
this resolution it can manage around 25fps streaming performance. A useful
feature of this app is the ability to configure settings via its web
interface, with options such as focus/exposure lock, which balance, flipping
and orientation control.
Pros
Inexpensive ($0.99)
Good performance
Useful settings available via web interface
Cons
JPEG only (no H.264 encoding)
No audio
iphcam-small4. iphCAM
This is an inexpensive and simple app that streams JPEG video over the local
network. Unfortunately its resolution is limited (maximum size 320×420)
and in our testing we wouldn’t coax more than 1 frame per second from it,
despite a strong WiFi signal and fast network. Due to the poor performance
of this app, we wouldn’t recommend it.
Pros
Inexpensive ($0.99)
Easy to configure
Cons
Poor resolution and frame rate
JPEG only (no H.264 encoding)
No audio
