SDL500-36X-The King of Long-focus&Rainy Season-Solar Security Camera

SDL500 is engineered for long‑term off‑grid surveillance. It combines a 36X motorized optical lens, dual 3MP imaging, foldable 20W (2×10W) monocrystalline solar, and a built‑in 20800mAh battery with BMS. Ultra‑low standby power and quick wake-up (0.2s) make SDL500 ideal for mid‑size farms, reservoirs, aquaculture, construction sites, islands, oilfield monitoring, and regions with extended rainy seasons. With PIR + AI human detection, 4G connectivity and cloud/local recording, SDL500 is a low‑maintenance node for remote security networks.

Quick overview — Key selling points

36X motorized optical zoom: long‑range targeting and evidence capture.
Foldable 20W monocrystalline solar panel (2 × 10W): saves shipping volume and provides flexible installation (integrated or separated).
Built‑in 20800mAh rechargeable battery (8×18650) with BMS for safe charging and discharging.
Ultra‑low standby: 0.003W standby power, 0.2s wake-up time. Under low-activity conditions, a conservative operational estimate can approach 360 days standby.

PIR + AI human‑shape detection, 7×24 continuous or event‑based dual recording controlled in the app.
Full‑color night mode (0.001 Lux) and combined IR/white light (80m).
4G support (multiple region versions), Android/iOS app, IP66 rating, two‑way audio (3W speaker + microphone).

Who the SDL500 is for
SDL500 is ideal when wiring or mains power is impractical and long autonomous operation is required:

Mid/small farms and ranches (livestock perimeter, gates, feed yards).
Reservoirs, levees and irrigation channels.
Aquaculture and fish farms.
Construction sites and temporary works.
Remote islands, oil/well pads, pipeline access roads.
Areas with seasonal or longterm low sunlight where maintenance visits need to be minimized.

36X motorized optical zoom — what “read at 3000 ft” actually means

Technical background: 36X refers to optical magnification range of the lens. A 3MP sensor (2560×1440) records detail, but readable license plates and faces at 3000 ft (≈914 m) require ideal conditions: stable mounting, good atmospheric clarity, correct focus/aim, slow or static targets, and minimal heat shimmer or fog.
Practical deployment tips:
- Use a rigid pole or fixed mount (reduce vibration) and lock PTZ presets on frequently monitored azimuths.
- Perform on‑site focus/calibration: take live snapshots at intended ranges during commissioning.
- Prefer morning/late‑afternoon checks to avoid midday heat shimmer.
- For continuous high‑accuracy recognition at extreme distances, consider multi‑camera overlap or higher resolution alternatives such as the SC‑PTZ‑5MP.
Realistic claim: In good visibility and with careful installation, SDL500’s optics + zoom can capture license plate and face level detail at long distances. Expect reduced performance in fog, heavy rain, dust, or heat haze.

Solar power & battery system: foldable 20W panel, 20800mAh battery & BMS

Foldable panel design: two 10W monocrystalline cells fold together for a smaller shipping footprint and easier installation. You can mount the panel integrated with the unit or separately where sunlight is best.
Nominal vs practical power: nominal 20W (2×10W). Under optimal tilt and clear sun, practical peak output is typically ~18W depending on sun angle and temperature.
Battery energy calculation (transparent example):
- Battery: 20800 mAh × 3.7 V ≈ 76.96 Wh.
- Idle theoretical time at 0.003 W standby: 76.96 Wh / 0.003 W ≈ 25,653 hours (~1,069 days). That number assumes no wake-ups and ideal energy accounting.
- Real‑world estimate: wake-ups (PIR events), 4G connectivity heartbeats, uploads and white light/IR events consume energy. Under a conservative low‑activity usage profile and solar recharge, SDL500 can achieve a practical long‑standby figure the manufacturer cites (up to ~360 days). Actual runtime will vary with trigger rate, upload frequency, night lighting use and local sunlight.
Recommendations for low-sun or rainy regions:
- Mount the solar panel where it receives the most unobstructed sun; adjust tilt seasonally if possible.
- For long rainy seasons or high-latitude installs, add extra panel area or a secondary battery pack, and set the device to “event‑only upload” mode to reduce data and power use.
- Schedule maintenance checks every 2–3 months in high-dust or heavy-rain environments.

Smart detection, recording modes & connectivity

PIR + AI human-shape detection: uses PIR to wake the device with minimal power draw; AI filters events to prioritize human/vehicle detections and reduce non‑action alerts.
Dual recording modes (set in app): 7×24 continuous recording or event‑triggered recording (dual-record mode lets you keep both local circular recording and cloud uploads for incidents).
Storage options:
- Local: TF card up to 128GB (loop overwrite).
- Cloud: alarm-triggered upload and remote retention; recommended for sites at risk of theft/vandalism (footage survives device loss).
Bandwidth & data: H.265 compression lowers bitrate and cloud costs. For heavy live streaming, plan your 4G data package accordingly; for event-only uploads, data usage is minimal.
App & remote: Android/iOS app provides live view, PTZ control, push notifications, timeline playback, and setting adjustments.

Imaging, night vision & audio

Dual 3MP lenses deliver wide-field view and telephoto capability for close inspection after zooming.
Night vision:
- Full-color night sensitivity: 0.001 Lux (full-color with white light).
- IR LED: 80m IR distance (black/white covert mode).
- White light LED: 80m (color mode, useful for forensic color detail; note this is visible).
Two-way audio: built-in microphone and 3W speaker; useful for warning intruders or communicating with onsite personnel. Voice monitoring effective up to ~20m depending on noise.

PTZ, coverage & environmental protection

PTZ movement: horizontal 355°, vertical 100°; horizontal speed ~55°/s, vertical ~40°/s for fast target acquisition.
Durable build: IP66 rated; operating temperature −20°C to +60°C; humidity 0–90% RH.
BMS (Battery Management System) protects battery charge/discharge cycles and increases service life.

Typical use cases & installation tips

Farms & ranches: place cameras high to cover fences and gates; set PIR sensitivity to avoid false triggers from small animals.
Reservoirs & levees: use presets to monitor access roads and shorelines; combine cloud backup for critical incident evidence.
Construction sites: install near entry/exit with PTZ presets for different shifts; pair with multiple SDL500s for full perimeter coverage.
Islands & oilfield pads: separate solar panel installation can be placed on clear, unshaded points; choose corrosion-resistant mounts on marine sites and consider protective coatings.
Low-sun areas: increase panel area and use event-only upload to minimize power drain.

FAQ

Q: Can SDL500 reliably read a license plate or face at 3000 ft?
A: Under ideal atmospheric and installation conditions (stable mount, clear air, correct focus, calm target), the 36X optical zoom with a 3MP sensor can provide readable detail at long distances. Performance drops in fog, heavy rain, heat shimmer or when targets move quickly. For guaranteed long‑range recognition under all conditions, consider higher-resolution PTZ (e.g., SC‑PTZ‑5MP) or multi‑camera setups.

Q: How does the foldable solar panel perform in rainy seasons?
A: The panel will produce less power in cloudy/rainy weather. For long rainy seasons, increase panel area, optimize tilt, or add a backup battery. Set the camera to event-only uploads to conserve energy.

Q: Is 360 days standby realistic?
A: 360 days is a conservative, low‑activity estimate based on the device’s ultra‑low standby draw and BMS. Real battery life depends on PIR triggers, uploads, night lighting, and local sunlight. We recommend a site energy assessment for critical deployments.

Q: Can I mount the solar panel separately from the camera?
A: Yes. SDL500 supports both integrated (all‑in‑one) and separated installation for maximum flexibility.
