It features an integrated UPS (Uninterruptible Power Supply) circuit with pre-wired red and black spade terminals. By adding a standard 12V sealed lead-acid (SLA) battery inside the enclosure, the system will automatically switch to battery power during a mains failure. The smart battery management system automatically charges the backup battery when AC power is active and stops charging when full to prevent overcharging and extend battery life.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2 id=\"4-individually-fused-channels-for-system-safety\" class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003e4 Individually Fused Channels for System Safety\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003eEvery output channel is protected by its own PTC auto-reset fuse and monitored by a dedicated red LED indicator. If one camera experiences a short circuit or power surge, only that specific channel's fuse will trip, leaving the other 3 cameras fully operational. Once the fault is cleared, the PTC fuse automatically resets itself without needing replacement. The LED indicators allow technicians to instantly identify which channel is experiencing an issue just by glancing inside the box.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 id=\"technician-tip\" class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003eTechnician Tip\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003eWiring this box is incredibly straightforward: the terminal block is arranged with the \u003c\/span\u003e\u003cstrong class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003eTop row for Positive (+)\u003c\/span\u003e\u003c\/strong\u003e\u003cspan class=\"ng-star-inserted\"\u003e and the \u003c\/span\u003e\u003cstrong class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003eBottom row for Negative (-)\u003c\/span\u003e\u003c\/strong\u003e\u003cspan class=\"ng-star-inserted\"\u003e. To ensure long-term reliability, never max out the 5A capacity; we recommend keeping your total continuous load under 4A (leaving a 20% headroom). The internal dimensions (23.2 x 18.6 x 7.3 cm) are perfectly sized to house a standard 12V 7Ah SLA battery (not included).
