Pyronix BatteryCam2
The Pyronix BatteryCam2 is the entry point into Pyronix's wireless range. 3MP colour video, a built-in siren and a front white light that activates on detection, giving both a visual and audible deterrent most cameras at this level don't include. Controlled through the HomeControl2.0 app, and it doesn't require a Pyronix alarm system to work standalone, though it integrates further if you're already running one. The battery is rechargeable but removable for charging, this is the camera to choose if occasional charging isn't an issue.
Pyronix BatteryCam2 Kit
The same camera as above, bundled with a 32GB microSD card and a SolarPanel2. With the solar panel fitted, the camera is continuously powered rather than needing to come down for a recharge, the practical choice for a position that's awkward to access or where you don't want to think about battery level again. Choose the Pyronix BatteryCam2 Kit over the standard BatteryCam2 whenever the install position gets reasonable daylight.
EZVIZ CS-C3A
A simpler, standalone wire-free camera with no siren or spotlight built in, 1080p video, a 5500mAh battery rated for around three months per charge, and a wider 125-degree field of view than the other three. The EZVIZ CS-C3A is the right choice for someone who wants straightforward wire-free coverage without the deterrence extras, or who's already invested in the EZVIZ app across other cameras. An optional EZVIZ W2D base station (not currently stocked by Harbro) adds a 100dB siren and extends battery life if that becomes a requirement later.
Ener-J SHA5319
The longest battery life of the four, up to 120 days per charge, on a 2MP sensor with a narrower 120-degree field of view. The Ener-J SHA5319 is the camera to reach for at a position that's genuinely difficult to get back to for a recharge, driveway gates, a remote outbuilding, anywhere checking the battery every few weeks isn't realistic. Two-way audio and PIR motion detection are standard, in line with the rest of the range.
