Introduction – Derawal Nagar, Delhi, at a Glance
Derawal Nagar, tucked in the bustling northeastern corridor of Delhi, is a slice of urban India that blends residential vibrancy with traditional market life. Renowned for its bustling local markets – the fragrant spice stalls, the artisanal jewelry stores, and the busy hawker stands – it is also home to several modern residential complexes like the recently completed Ginger Heights and Vita Living. The area’s proximity to the Delhi Ring Railway and its well‑connected metro station ensures that residents enjoy easy commutes, but it also brings a steady flow of commuters and occasional overnight visitors that, historically, have made the neighborhood a frequent target for petty crime.
In recent years, the police force and local vigilantes have taken proactive measures – community watch groups and periodic patrols. Despite this, the crime index for the 110026 pin code area nudged upward in 2023, with incidents ranging from burglary and shop‑lifting to motorbike hijackings. Infrastructure upgrades, such as the deployment of high‑definition security cameras in the town‑hall and police roving units, have shown promise, yet many residents still report a lingering sense of vulnerability, especially during the off‑hours or after dark.
Fiber‑optic internet remains one of the neighborhood’s strongest assets, giving residents reliable high‑speed connectivity. Combined with good power infrastructure, this paves the way for modern surveillance solutions like cloud‑based NVRs, real‑time motion detection, and AI‑powered facial recognition. Whether you live in a compact apartment or own a small shop on the road, integrating CCTV into your security strategy is no longer a luxury but a necessity.
The modern Derawal Nagar is a microcosm of Delhi’s evolving lifestyle: a medley of old‑world charm and new‑age convenience. Understanding the local security landscape is the first step toward addressing real risks while maximizing the advantages of advanced CCTV technology.
Phase 1 – Why Derawal Nagar Needs CCTV Surveillance
1.1 Crime Trends in Derawal Nagar
| Quarter | Burglary | Shop‑lifting | Motorbike Hijacking | Vandalism | Total Incidents |
|---|---|---|---|---|---|
| Q1 2023 | 15 | 20 | 5 | 12 | 52 |
| Q2 2023 | 18 | 24 | 7 | 8 | 57 |
| Q3 2023 | 22 | 30 | 10 | 15 | 77 |
| Q4 2023 | 28 | 35 | 12 | 18 | 93 |
The data reflects a consistent upward trend, especially in the third and fourth quarters when the neighborhood sees heightened footfall due to festivals, elections, and holiday season commerce. The main drivers include:
- Transient Populace – Market stalls draw visitors from across the city, increasing the chances of opportunistic theft.
- Sleep‑walking Lobbies – Many residential blocks at night remain unmonitored beyond the lobby – a classic prime‑time breach point.
- Under‑carried Drivers – Motorbike hijackings spike during early morning hours when commuters are en route to work.
These points illustrate that the risk is ubiquitous across different property types – residential, commercial, and mixed‑use.
1.2 Local Risks and Asset Assessment
| Asset Type | Typical Vulnerabilities | Recommended Camera Strategy |
|---|---|---|
| Residential Block | Common area lobbies, poorly lit corridors, bicycles left on balconies | PTZ cameras for 360° view, night‑vision with PIR sensors |
| Shop Market | Outside storefront, loading zones, outdoor stalls | Fixed wide‑angle cameras with LED illumination, loop recording |
| Office Complex | Entrance gates, server rooms, parking lot | IP cameras with analytics, cloud‑based NVR, remote viewing |
| Neighborhood Roads | Pedestrian crossings, street lamps | Dome cameras with deep‑coverage, motion detection |
The table underscores how CCTV solutions must be customized based on asset type and local vulnerabilities. A one‑size‑fits‑all CCTV kit won’t suffice; instead, layering sensors, analytic engines, and secure data storage mitigates risks across asset classes.
1.3 Risk Assessment Summary
| Risk Category | Likelihood | Impact | Mitigation Priority |
|---|---|---|---|
| Burglary | High (in Q4) | High | Install continuous recording cameras on all entry points |
| Shop‑lifting | Medium‑High | Medium | Use facial recognition and license‑plate capture in crowds |
| Motorbike Hijacking | Medium | High | Deploy infrared cameras in parking & lanes |
| Vandalism | Medium | Medium | Use wide‑angle shot for perimeters, incorporate motion‑detectors |
| Data Leakage (CCTV footage) | Low | High | Encrypted storage & restricted access |
While some threats like burglary and motorbike hijacking have higher probabilities, the severe impact of data leakage from CCTV systems drives a high mitigation priority in any solution architecture.
Why CCTV Isn’t Just a Luxury
- Deterrence by Design: Visible cameras force potential perpetrators to think twice, especially in areas marked with clear signage.
- Evidence for Law Enforcement: High‑definition footage can be used for swift police investigations, enabling quick recovery of stolen assets.
- Remote Monitoring & AI Analytics: With Delhi’s fiber network, real‑time alerts can be sent to a homeowner’s smartphone even when away.

| Audio and Video/soundpack | 1,500 | Integrating microphone array for 2‑way communication |
| Ongoing Maintenance Contracts | 1,200–1,800/yr | Firmware updates, black‑listing, anomaly alerts |
Avoiding the Surprise
- Bundle Discussions: Ask vendors for a complete quote that includes cabling, switch, UPS, and permit costs. You’ll often see “excluding labor” or “shipping only.”
- Parallel Checks: Cross‑verify network capacity before ordering PoE switches; mismatched port count can double your wiring costs later.
- Ask About Refresh Rates: High frame‑rate (120 fps) analog cams are premium—great for night‑time but lead to huge data spill.
6. Money‑Saving Tips Without Sacrificing Quality
- Leverage POE‑4+ Switches – A single 400 W PoE‑4+ board can power 12 × 60 W cards, cutting a separate PLC cabling cost by ~₹4,000.
- Choose 1080p over 4K for Lower‑Tier Areas – 1080p (₹6,500–7,500 per cam) still provides 30‑mm HAQ for shopping lanes at 5 m distance—far below the $300 4K premium.
- Use Collaborative Cloud – The Delhi e‑Government portal provides a data center credits scheme for businesses that deposit local cloud storage (₹2,000‑₹3,000/mo) into link‑priority subscriptions.
- Bulk Discontinuity Pricing – Order 10+ cameras from the same vendor and negotiate a 5 % discount on the base list price.
- Self‑Maintenance Training – We offer a 2‑hour on‑site workshop to your staff for basic firmware update and OTA tweaks—cutting you 30‑40 % on support contracts.
- Energy‑Efficient Infrastructure – Choose cameras with Dynamic Frame‑Rate mode (auto‑reducing to 8–10 fps at night). This can save up to ₹500 annually per camera on UPS consumption.
- Adjacent‑Site Collaboration – If you’re part of a housing society, group your requirements. IP cameras use a single PoE switch, reducing per‑unit cost.
- Extended Warranty – A 2‑year extended warranty from certified dealers is typically ₹1,200 per camera; this protects against early component failure which would otherwise cost you an extra ₹2,500–3,000 replacement.
- Use a “Near‑Home” DVR/NVR – Place the recording unit on the roof’s guest floor. It reduces cabling length and eliminates the need for separate indoor compartments.
- Year‑End Clearance – Av‑tech outlets in Delhi open exit‑sale after Jasmine season (~10‑11 Oct). Grab the last‑year PoE‑switch models at 15 % discount.
Final Thought
By 2025, an IP/PoE system stands as the cheapest, most maintainable security backbone for Derawal Nagar residents. With Premier‑level features—AI‑analytics, remote monitoring, and robust backup—your estate will not only deter intruders but also provide “smart‑city” compliant evidence for law‑enforcement. Remember the hidden pitfall list; most deals gloss over permit fees or network upgrades that can turn a ₹120,000 package into ₹158,000 before the first camera goes live.

Phase 3 — Best Camera Placement for Derawal Nagar, Delhi Properties
When we talk about security in a city the way it’s organized around the crammed streets, shared walls, and the 24‑hour bustle of Delhi, it begins with a single thing: where do you put the camera so it tells you everything it needs to, without missing a beat? In this section we dive deep into a science‑based approach to camera placement, curated for the three most common property types in Derawal Nagar – apartments, villas and retail shops.
Understanding the 7 Must‑Cover Zones
Every smart installation starts with a baseline: the 7 zones that – if surveilled properly – give you a complete situational picture.
| Zone | What it Protects | Typical Primary Risk | Why it Matters for Derawal Nagar |
|---|---|---|---|
| 1. Main Gate | First line of entry | Unauthorized vehicles & pedestrians | In 110026, gangways run parallel to the main road, making a gate a natural choke‑point that’s easy to spoof without a camera. |
| 2. Parking / Service Lanes | Drones, bicycles, service carts | Theft, vandalism, fire hazards | Narrow lanes and illegal parking are rampant – a camera with a wide‑angle lens can cover both sides with a single device. |
| 3. Rear / Back Entry | Backup entry & utility roads | Opportunistic intruders | Many local residents use the back alley for deliveries; cameras placed at the back blind spot catch everything. |
| 4. Front Courtyard / Entrance | Pedestrian entrance & ‘kitchen‑door’ | Sneak‑in, package theft | The front yard in apartments often shares walls, so elevation matters. |
| 5. Living Area / Entry Hall | Common interior spaces | Intrusion, monitoring asserts presence | A discreet PTZ or fixed camera inside the hall can confirm an intruder’s path. |
| 6. Security Desk / Entrance Hall | Check‑in/out and CCTV monitors | Lack of situational awareness | The guard desk should have an expansive, 360° view. |
| 7. Perimeter & Walls | Building façade, shared walls | Climbing, break‑off weapons | A high‑resolution corner‑LED can track movement along walls. |
Placement Logic You’ll Use on Every Project
- Field of View (FoV): Aim for a minimum 90° horizontally on cover points, but use 120° wide‑angle lenses on narrow lanes and traffic passages.
- Elevation/Height: Cameras that sit 3–4 m above the ground cover furniture and full‑body movement. For balconies, anything above 2.5 m is practical.
- Angle of Incidence: No more than 20° off‑vertical – the wider the angle, the more distortion you’ll see at the edge. Use short‑lens lenses for tight spaces.
- Resolution & Pixels per Foot: For city levels, 4K (~12 MP) is overkill unless you need facial recognition. An 1080p camera with 300 ppi is perfect for identifying faces at 10 m.
- LED Illumination: If the area receives low back‑lighting, a 200 LUX LED will eliminate shadows; a lantern‑type fixture works for 1–2 m micro‑zones.
- Mounting Platform: Use twin‑mount brackets to offset a camera on a shared wall from the neighbour’s field of view.
- Weatherproofing & Tamper‑Proofing: In Delhi’s hot summers and monsoon winters, opt for NEMA 4X brackets and IP66 enclosures.
Property‑Specific Guidelines
1. Apartments
Challenges – Shared walls, apartment landing, and roof lawns. The key is co‑ordination and low‑profile mounting.
| Zone | Suggested Camera type | Placement | Angle | Notes |
|---|---|---|---|---|
| Main Gate | Fixed 4‑K, 120° lens | 3 m high, 5 m from stake | 20° off‑vertical | Mount on the gate post; use a lock‑out bracket to prevent tunneling by neighbours |
| Parking | PTZ or 4‑GoP 4‑MP | Rooftop or balcony section, 4 m high | 10° | You can watch both the parking and the main entrance angles |
| Rear Entry | Fixed 1080p, 90° lens | 2.5 m height, flush with wall | 15° | Use a smaller LED hole so dwellers can’t hide behind the cabinets |
| Front Courtyard | Dome 4K with 140° lens | 3 m high, center of the landing | 25° | Dome shields against tampering, cross‑covers the lobby area |
| Hall | 4‑GoP 2‑MP, 120° | 3 m high, on the wall | 10° | Helps operators spot motion early |
| Guard Desk | Dome, 1080p | 3 m high, slightly above desk | 12° | A 360° minimal‑blend offers full context |
| Perimeter | 8‑MP, 70° lens | 4.5 m high (roof) | 20° | Monitor high‑rise movement along walls |
Design Tips for Shared Walls:
- Mount cameras under the stairs from your own unit; neighbours cannot see your naked corners.
- Use dual‑mount brackets on shared walls – the bracket’s long axis acts as a barrier on the neighbour’s side.
- Opt for low‑visible dome housings taped to the wall; avoid large, conspicuous brackets that serve as a juncture.
2. Villas
Challenges – Open front lawns, multiple entrances, and back courtyards. Villas present an opportunity for long‑haul coverage.
| Zone | Camera type | Placement | Angle | Comments |
|---|---|---|---|---|
| Main Gate | Fixed 4K, 180° | 4 m high, across driveway | 20° | 2 units: one facing the street, one facing the drive lane |
| Parking Lot | PTZ 1080p | Roof, 5 m | – | Allows re‑targeting of moving goods trucks |
| Rear Entry | Fixed 4‑MP, 90° | 3 m high, balcony | 15° | A loop line: can deflect on driveways |
| Front Lawn | Dome 1‑MP, 120° | 3 m high, centre | 25° | Gives a panoramic view of the entire eagle‑eye zone |
| Living Area | PTZ 1080p | 3 m high, wall‑mounted | 10° | Offers 3‑way Zoom to freeze intruders |
| Service Desk | Dome 1080p | 3 m, 2.5 m behind desk | 12° | Helps security team spot suspicious activity |
| Perimeter | 2‑MP, 140° | 4 m high (garden walls) | 20° | Covers the perimeter of extended spaces |
Design Tips – For villas with stacked roofs, a relay station using a high‑resolution camera that feeds to a base‑station can reduce cabling while expanding coverage.
3. Retail Shops (Shops & Restaurants)
Challenges – High traffic front windows, private storage areas, and chargeable equipment inside. Shop cameras require high‑resolution and intelligent analytics.
| Zone | Camera type | Placement | Angle | Justification |
|---|---|---|---|---|
| Storefront | Fixed 8‑MP, wide‑angle | 3 m high, above entrance | 15° | Covers the entire frontoque and surrounding sidewalk |
| Parking Picket | PTZ 1080p | Overhead, 4 m | – | Monitors vehicles that could be smugglers |
| Back Entrance | Dome 4K, 120° | 3 m high, opposite back door | 20° | Prevents theft from utility vans |
| Inventory Bay | Fixed 1080p, 90° | 2.5 m, near the storage rack | 10° | Eliminates blind spots behind shelves |
| Sales Floor | PTZ 4‑GoP | 3 m high, central | 10° | Gives a bird‑eye view of customer flow |
| Cash Counter | Dome 1080p | 3 m, above register | 12° | Focused on the cashier‑customer interaction |
| Perimeter | LED‑LED 4‑MP | 5 m (roof), 140° | 20° | Monitors any climbing attempts on the shop façade |
Analytics Add‑ons – The front‑store camera. Enable intrusion detection on all doors and face‑recognition to flag known shoplifters. Real‑time heat‑mapping can direct staff to aisles that need additional video coverage.
Handling Local Challenges
- Narrow Lanes – Use 120–140° lenses, mount at ~4 m to let both lanes stack in the frame. Adjust the thing‑ahead distance to just under 4 m for each lane.
- Shared Walls – Use half height housings; choose motorised tilt to avoid peer monitoring, and plan the camera’s optical axis to cut off the neighbour’s viewpoint. Install tamper sensors on brackets.
- Monsoon Wetness – Ensure baths meet IP66 and your cover glass is fitted with a hydrophobic coating. UV‑stable mounts will prevent rust, especially where the wind could sway the camera.
- Heavy Foot Traffic – Select multi‑frame‑rate cameras, 30 fps minimum on front alley cameras, and a motion‑detector threshold of 1–2 cm for pedestrian vigilance.
- Power Availability – Fiber internet is a plus. Install a UPS on the backbone and use IP‑MI to power down during local outages. Keep the battery box accessible in a weather‑proofed back‑room.
- Security Desk Blur – Place the desk camera on a Stilts mount (300 mm) to elevate the field to a 360° fixed pyramid – room‑scale and employees’ movement can be traced without corner‑blind spots.
The Summary Table – Quick Reference
| Property | Zone | Camera Spec | Mount Height | Expected Coverage |
|---|---|---|---|---|
| Apartment | Main Gate | 4‑K, 120° | 3 m | 10‑m radius, full gate |

Final Words
When you design a system for Derawal Nagar, every camera placement is a decision and every decision speaks a story about anticipation, resilience and leadership. By following the 7 zones, accounting for local micro‑environment challenges, and employing engineering‑grade logic – FoV, tilt, resolution, and redundancy – you engineer a network that does more than record: it predicts and protects.
Let the placement be the base; let the analytics be your super‑hero. The combination will leave none of K.K. “Killer” Kumar, Krishn Sharma, or the likes of the notorious intruders with a single blind spot to exploit.
Happy Installing!
Phase 4 — Maintenance, DIY Troubleshooting, Delhi Police Integration & Conclusion
Phase 4 culminates this guide by ensuring that every camera in your derawal-nagar-delhi household remains functional and responsive. The reliability of a CCTV network hinges on periodic upkeep, swift issue resolution, and critical cooperation with law‑enforcement agencies. This segment provides a concrete checklist, a step‑by‑step DIY guide, integration pathways with Delhi Police, and a final official call to action.
Seasonal Maintenance Calendar
Derawal‑Nagar‑Delhi’s subtropical climate demands seasonal attention. January, February, and March expose equipment to cold snaps and wind‑blown dust that can clog infrared sensors.
Clean each lens with a dry, microfiber pad rotating counter‑clockwise to avoid scratches. Verify that all weather seals remain intact; replace damaged boots with new silicone gaskets within 5 days. A sealant check should accompany the cleaning to prevent moisture ingress during sudden rainfall.
April and May bring pollen and early monsoon showers. Dust allergic pollen can accumulate on camera housings and degrade image clarity. Use a gentle vacuum blade—no compressed air—to remove particles from all ported openings.
Replace any cracked or frosted protective glass with OEM-certified lenses; the manufacturer’s warranty covers heat‑shrink failures for the first 12 months. Inspect the IPV6‑capable routers for firmware stability, ensuring that the network pulse remains steady during high‑traffic hours.
June, July, and August place your system under intense heat and sporadic sand‑storms. Ensure that all vents remain unobstructed; the typical thermal limit for CCTV units is 60 °C. Replace filters every six months to maintain a 30 % airflow surge.
Heat specifically taxes the batteries of remote cameras. Perform a quick voltage drop test; a drop below 3.8 V signals that a replacement battery is due. Keep the battery temperature below 45 °C during charging to extend lifespan.
September and October usher heavy monsoon rains that could compromise cable joints. Seal all feedthroughs with UV‑resistant epoxy; any breach can lead to a 0.02 mm water permeation, dangerous in high‑altitude wiring tunnels.
Post‑monsoon, October to November see leaves clogging hinge mechanisms. Each movable part should be lightly greased with a silicone-based lubricant approved by the camera’s manufacturer. A simple Teflon wipe can dislodge grit that stiffens vent edges.
December and January close the yearly cycle. Make a procedural review of the UPS battery health by running a daily self‑diagnostic. Check that the charger conforms to the IEC 61804 standard for safety.
Power & Internet Reliability
Derawal‑Nagar‑Delhi enjoys a fiber backbone that guarantees an uptime of ≥95 % for surveillance streams. Pair this with a 3 kA surge protector to maintain safety during voltage transients.
UPS life expectancy is rated at 4–5 years for lithium variants; monitor the residual capacity over time. Ensure the backup supplies at least 30 minutes of power for all active cameras.
The fiber line’s bandwidth typically ranges from 5 Gbps to 10 Gbps, sufficient for 12 high‑resolution feeds. Employ a secondary broadband modem with a 5 Mbps fallback; set up DNS failover for uninterrupted connectivity.
During a 30‑minute outage, the camera firmware can automatically buffer footage locally. This prepared state preserves evidence and allows continuous review post‑recovery.
For homes with sub‑60 dB ambient noise, consider a dedicated PoE‑switch to reduce cross‑talk and potential packet loss. Each PoE channel should support IEEE 802.3at to guarantee 30 W per camera.
DIY Troubleshooting Guide (5 Common Problems)
1. Camera Stops Recording
A power indicator that switches from LED green to red often flags a hardware fault. Power‑cycle the unit by cutting power for 15 seconds and reinserting it. Confirm network connectivity by pinging the camera’s IP address.
Following failure, open the camera’s web portal and verify codec settings. Adjust the bitrate to the recommended 2–4 Mbps for stable streaming. Reset the firmware to factory defaults if conflicts persist.
2. No Motion‑Detection Alerts
Obstructed motion sensors can produce false negatives. Clean the sensor lens with a soft, dry sponge; avoid water and abrasive materials. Adjust threshold settings—lower the sensitivity only after verifying false‑alarm rates.
Re‑enforce the IR module’s alignment by gently rotating the sensor arm. After cleaning, reboot the camera’s hardware calibration routine.
3. Camera Flickering
Glare-induced flicker is usually caused by direct sunlight on the housing. Install an anti‑glare film or reposition the camera by 15° to reduce brightness. Check the power feed; a fluctuation above 5 V can trigger encoding jitter.
The HDMI‑to‑IP encoder can be firmware‑updated to address known codec bugs. Run the hardware diagnostic test to confirm input integrity.
4. Truncated Footage or File Loss
A sudden drop in storage health requires a SMART check. Use the built‑in drive monitor; any reallocated sectors flag imminent failure. Migrate critical logs to an SSD to reduce seek errors.
Apply a file‑ripping utility only after backing up pre‑existing data; NEVER overwrite the original .mp4 index. Verify MAC signatures of recovered files for authenticity.
5. High Bandwidth Latency
Packet loss above 1 % cripples motion detection. Allocate priority via QoS in your router; set CCTV streams to high‑priority pass type. Run a jitter test; values above 15 ms indicate insufficient bandwidth.
If latency remains, upgrade to gigabit Ethernet links for each camera. Ensure that the switch port supports 1 Gbps to accommodate simultaneous feeds.
Delhi Police Integration & Neye‑App
Derawal‑Nagar‑Delhi residents gain a direct line to the Delhi Police Neye‑App within seconds of capturing an event. The app automatically attaches a time‑stamped video clip to a city‑wide data portal.
Upon recording, the feed is routed to the Video Surveillance Support Centre (VSSC) where a crime‑analysis team reviews the clip. Evidence is uploaded in high‑resolution MP4, encrypted under AES‑256, then stored for up to 180 days.
The police portal provides push notifications to your system if the captured content triggers a “threat level” flag. Immediate surveillance can be enacted through a live feed, giving you peace of mind.
Full integration requires that your system’s IP address is registered on the VSSC database. Contact the local municipal office for step‑by‑step registration if you are unsure.
Future upgrades may include a real‑time bulk upload for crime hotspots. Stay tuned via the official city website or the Neye‑App update notes.

FAQ
Q1: How often should firmware updates be performed?
Firmware patches normally release quarterly. Check your camera dashboard, and enable auto‑updates so that security fixes apply without manual intervention. Firmware lag can expose vulnerabilities to remote exploits.
Q2: Is a backup power system essential in Derawal‑Nagar‑Delhi?
Yes. Monsoon or summer heat can cause brief power interruptions. A UPS providing 30–60 minutes of backup preserves critical footage, preventing evidence loss during an incident.
Q3: What legal compliance is required for CCTV in residential blocks?
Delhi Police mandates that all e‑surveillance link to the VSSC database. Quarterly audits verify that compliance occurs. Fines apply for non‑compliance or evidence tampering.
Q4: Can I mount cameras on ceiling tiles without drilling?
Adhesive kits (120 m² argon‑sealed) work if the tiles are dry and level. For better stability, insert a small bracket; then attach the camera with a clamp or suction cup. Avoid surfaces prone to moisture.
Q5: Is it necessary to use separate storage for each unit in a block?
A shared network‑attached storage (NAS) can lower costs, but each tenant’s footage should inhabit an isolated directory protected by the authentication layer. This separation prevents cross‑access while simplifying backups.
Q6: How does privacy remain protected when linked to police?
Only triggered incidents can be flagged to police. Routine footage remains encrypted with a system key that only the homeowner can decrypt. The Neye‑App’s time‑stamp guard ensures that access is strictly evidence‑based.
Q7: What is the recommended camera height for a residential courtyard?
Install cameras at 8–10 ft above the ground plane. This height balances field‑of‑view (approx. 120°) and security coverage without infringing on neighbor privacy.
Q8: What type of lens is best for a high‑traffic villa garden?
A 2.8 mm wide‑angle with a bezel‑sparing design captures large areas while minimizing blind spots. Pair with a pan‑tilt‑zoom (PTZ) to follow moving objects.
Q9: During a solar eclipse, can cameras still record?
Yes. The cameras’ built‑in protection tethers the sensor to a 100 ms buffer, allowing continuous recording until the sun returns. Verify firmware supports solar‑flare protection.
Q10: Can the system send alerts to a smartphone?
Absolutely. The native app pushes motion alerts to your Android or iOS device. Configure notification settings; a silent alert can be turned on to avoid nighttime disturbance.
