Night Vision WiFi Cup Camera WF-720CUP
50 hours of recording, more than twice any other model here
From nine minutes to fifty hours across one catalogue. Where the difference comes from and how to read a runtime figure before you quote it to a customer.
In this catalogue the DVR-1080TIC runs 9 minutes on 380mAh and the WF-720CUP runs 50 hours on 15000mAh. That is a factor of three hundred. Anyone quoting a covert camera without checking the runtime figure is going to disappoint a customer.
The WF-1080DTC runs 3.5 hours on 2500mAh. The DVR-1080PWC runs eight hours on 4200mAh. The capacity is 68 percent higher but the runtime is 129 percent higher, because the WiFi model is also keeping a radio alive. Compare runtime figures, not milliamp hours.

The DVR-1080TIC and the DVR-1080SWC both record while charging. Nine minutes of battery is irrelevant when the unit is running from a power bank or a USB socket. For any placement near power, treat the battery as a bridge rather than a limit.

The WF-1080ULC desk lamp runs from USB. The WF-360BUB bulb camera runs from a lamp holder. The WF-720PWC and WF-720WCC wall clocks have no battery at all. If a socket or a lamp holder is available, the runtime question disappears.

Ask three questions. Is it continuous recording or PIR standby? Is night vision on, because the infrared array on the DVR-1080PDC draws 1400mA against 230mA for video alone? And is the figure from the factory sheet or from a marketing page? We publish the factory figure and mark anything we cannot verify as to be confirmed.
50 hours of recording, more than twice any other model here
Records while charging, which turns 9 minutes of battery into unlimited runtime on a power bank
Eight hours of continuous recording with no mains connection at all
128GB card support, the highest capacity the catalogue offers
On continuous recording, the WF-720CUP at 50 hours. On PIR standby, the DVR-1080BKC and the WF-720PFC at around a year.
A 380mAh cell in a body that size cannot do more. It is designed to record while charging.
Considerably. On the DVR-1080PDC the infrared array draws about six times what video recording alone draws.
