About this replacement
IES Kami Home Security Camera — 3.7V Li-ion Replacement Battery (IBR072GC)
This 3.7V, 6000mAh Li-ion battery replaces part IBR072GC in the Kami wireless home security camera. It fits the AD201-1 platform and carries the same cell dimensions (70.30 × 45.80 × 21.00mm) as the factory unit. Slot it in and the camera powers on without any hardware modification.
- Kami AD201-1 platform fit: The AD201-1 and IBR072GC share a single battery bay spec — same connector pinout, same voltage rail, same BMS communication protocol. One cell fits both references.
- Bench tested on actual hardware: We cycled this cell through repeated motion-trigger events and monitored BMS behaviour under the combined IR LED and processor current spike. The BMS held threshold through sustained draw without tripping.
- First-install power cycle: After fitting the battery, power cycle the camera once through the Kami app. The firmware must register the new cell before motion events log correctly to cloud storage — skipping this step can cause silent recording gaps.
App showing 0% or wrong battery percentage after swap
Kami cameras use a voltage-threshold indicator, not a fuel gauge IC. When a new cell goes in, the camera reads the resting voltage and maps it to a percentage — but that mapping only stabilises after one full charge-discharge cycle. A freshly installed 6000mAh cell sitting at 3.85V can report 0% or a random low number until the firmware calibrates its threshold table. Run one complete charge cycle through the camera's normal charging port, then check the app again. The percentage should settle to an accurate reading by the end of that first cycle.
Recording stops mid-clip on weak WiFi signal
When the camera's WiFi link is marginal, the radio module pulls a current spike each time it retransmits packets to maintain the upload stream. That spike, layered on top of active recording draw, can push instantaneous current above the BMS protection threshold and trigger a brief cutoff. The camera reconnects, but the clip ends there. Move the camera within reliable signal range of the router, or add a WiFi extender — the BMS will not trip at the same draw level once the radio stops retransmitting. Target a signal of at least -65 dBm at the camera's location.
